WHITE PAPER—Inkjet versus Laser BLI Test Methodology The information contained in this report was obtained from independent testing conducted in Buyers Laboratory’s 10,000-square-foot US test facility in Hackensack, NJ, and its 3,000-square-foot UK test lab in Wokingham, UK. The unique evaluations, hundreds of which are conducted every year, cover all the important aspects of performance and take about two months to complete. The comprehensive battery of tests includes an extensive reliability test during which printers and multifunction printers are run for half of their manufacturer-rated maximum monthly duty cycle over the course of 15 days. The volume output each eight-hour workday varies, and includes a mix of short, moderate and long run lengths, and on/off cycles, to simulate real-world usage. For MFPs, 25 percent of the test volume consists of copy jobs and 75 percent consists of print jobs. Half the output is in simplex mode and half is in duplex mode. Roughly 70 percent of the test volume is produced on virgin paper, and 30 percent is produced on recycled media (comprised of 30%, 50% and 100% recycled paper). To eliminate performance issues that could be paper related, BLI uses a few standard paper sources. In the US lab, papers used are Georgia-Pacific Spectrum Multi-Use 20-lb. virgin bond, Boise X-9 20-lb. virgin bond and Boise Aspen recycled paper. Image quality is tested using Georgia-Pacific Printing Paper with ColorLok (96 brightness, 22-lb. bond). Papers used in the UK lab are UPM 80gsm multi-purpose paper and m-real Evolve 100% recycled media. Image quality is tested using UPM 100gsm color laser paper. All products are powered by dedicated circuits that are protected by ESP (Electronic Systems Protection, Inc.) surge protectors to prevent transient power and communication disturbances from affecting equipment under test. They are installed on BLI’s dedicated test network, which consists of Windows 2003 and Microsoft Exchange servers, Windows 7 workstations, 10BaseT/100BaseTX network switches and CAT5 cabling. Temperature and humidity are maintained at levels typical of an office environment and conditions are monitored by an Extech RH S20 Digital RH/Temperature Recorder and Honeywell Model 61 Seven-Day Temperature/Relative Humidity Chart Recorder. In addition to a number of proprietary test documents, BLI uses an industry-standard KATUN test original for evaluating black image quality and a proprietary suite of BLI- developed test targets to evaluate color image quality. Trained technicians perform a visual observation of all output under a Graphiclite D5000 Standard Viewer; color print quality is tested using a color test target, which is read using the X-Rite Eye-One/iO Color Spectrophotometer, and samples are analyzed using the CIE XY Chromaticity Diagram. Density of black and color output is measured using an X-Rite 500 Series Densitometer. Electricity is automatically regulated to
WHITE PAPER—Inkjet versus Laser Brief History and Evolution of Inkjet Technology Since the emergence of the first desktop inkjets in the 1980s, the technology has not only undergone a number of significant changes and improvements, but has also been through cycles of being loved and hated by business users. As the technology evolved, the printers themselves became so affordable that, it seemed, nearly every user could have his own desktop inkjet printer with almost no investment or management approvals necessary. In fact, computer companies sometimes gave inkjet printers as free gifts with PC purchases. When it came time to replace the ink, however, it became apparent just how expensive it could be to maintain this “cheap” technology. In the past few years, though, vendors began veering away from the marketing model of practically giving away the hardware and selling the ink at inflated prices. Business-class inkjets gained favor in the office as entry-level devices. These desktop machines offered a low upfront cost, acceptable quality on plain paper and, in most cases, a better cost per page than sub-$500 color laser models. But they were very slow, generally maxing out at about 10 ppm in the real world, making them suitable for only low-volume usage. Speed was even more of an issue for documents that needed better quality; in the units’ best- quality mode, they slowed down even more and cost per page increased because of the higher page coverage, resulting in greater ink consumption. While some printer companies have exited the office inkjet market, others have created a new breed of devices. While only a handful of products exist in this new category, the industry is seeing a major revitalization and reinventing of inkjet technology in products like the 60-ppm Memjet C6010, 100-ppm monochrome-only Brother HL-S700DN and, most important, because of HP’s dominance in the industry, the HP Officejet Pro X Series. In this report, BLI’s lab team and analysts wanted to dig deeper and provide further insight on this new trend in business inkjet, focusing specifically on the recently tested HP Officejet Pro X576dw MFP, to provide analysis of both print and copy functionality using this technology. HP’s PageWide Inkjet Technology With the announcement of its new inkjet technology, HP says it is delivering the quality, speed and affordability of a workgroup laser device, with the low power consumption, easy maintenance and low waste of an inkjet device. But can this technology really compete in the mostly laser-centric business environment? BLI has put the technology to the test, analyzed the data and crunched the numbers (using our lab test data from the recently introduced Officejet Pro X576dw), to help you determine in what cases ink can truly rival laser technology and if it is ultimately the right choice for your business.

WHITE PAPER—Inkjet versus Laser PageWide Array: What It Is and What It Does… The Officejet Pro X series printers and MFPs (pictured above) borrow the robust body and paper drawers from HP’s LaserJet family of products, but inside, they are inkjet machines. At time of publication, the Officejet Pro X series consists of six models: the Officejet Pro X451dn/X451dw and sister MFPs, Officejet Pro X476dn/X476dw (with a default mode speed of 36 ppm and as fast as 55 ppm in General Office Mode), and the Officejet Pro X551dw and sister MFP, Officejet Pro X576dw (with a default mode speed of 42 ppm and as fast as 70 ppm in General Office Mode). PageWide technology is so named because the series of staggered, overlapping clusters of nozzles it uses span the width of an 8-1/2" page. That’s in contrast to the couple of inches covered by the printheads of most typical business inkjet products. Rather than travelling back and forth on a carriage to deliver ink droplets across the page, the new HP printhead is stationary; the page moves under it during the imaging process. The most obvious advantage of a stationary printhead is, of course, speed, since only the page needs to move through the printer while the printing element is fixed in one position (much in the way a page moves through a laser printer). Another key advantage is image quality. In traditional inkjet printers, the printhead moves back and forth and the faster the printhead moves, the more likely output will exhibit banding from the back and forth motion.

WHITE PAPER—Inkjet versus Laser While traditional inkjet technology (pictured top) uses printheads mounted on a carriage that moves back and forth on a track to print the page, HP’s PageWide array (pictured bottom) uses a single wider printhead with 10 dies (clusters of nozzles, with a total of 42,400 nozzles) to span the width of the 8-1/2" page. The Officejet X series uses four pigmented inks, rather than dye-based, which, according to HP, deliver brighter, more saturated color. MODELS FOR COMPARISON According to HP, the new Pro X models compete against small workgroup devices that are roughly in the same price range. While there are print-only and MFP versions of the series, BLI chose the Pro X576dw MFP as the subject of this report in order to provide the most comprehensive comparison, including copy functionality. BLI’s test results on this model were compared against those of 10 tested laser/LED models that fall into this category. But, because of the HP unit’s higher speeds, BLI also chose 10 mid-size workgroup laser models that offer similar rated speeds as the X576dw. BLI focused on the aspects of performance that can be affected by technology, including, speed, image quality, energy consumption, cost of ownership and waste generation. And because reliability is the most important aspect of any product, we also compared reliability.

WHITE PAPER—Inkjet versus Laser SUMMARY OF FINDINGS BLI’s testing revealed the Officejet Pro X576dw to be a very strong performer in many areas evaluated, making it an excellent choice for many business users. While it may not be the best choice in environments with monthly volumes greater than 5,000 pages (at these volumes, some higher-end laser models become more cost effective), the HP Officejet Pro X576dw is an ideal replacement for laser devices in low- to mid-volume business environments that need affordable color output. Its greatest strengths are its fast speeds, low power consumption and minimal waste generation. Print quality and reliability are on par with or slightly better than some of the laser models in the test group (both small workgroup and mid-size workgroup devices), falling short only in printed halftone output and in copy output, especially in the area of copied text, with black density readings that were lower than that of the laser model with the lowest density readings. When compared with the small workgroup laser models tested, the Officejet Pro X576dw is a force to be reckoned with. Indeed, in its default mode, it was the fastest in 18 out of 20 productivity tests, including for printing or copying a single page in color and black (this is especially significant, since many typical print jobs are one to three pages in length), and also when printing or copying sets of single- and double-sided documents in color and black. In fact, in some of the single-page tests, it was twice as fast as the average. When printing BLI’s job stream test, however, in which nine typical office documents of various file types are released to the printer at once, the inkjet unit paused between jobs and was slower than the average for the laser models. The job stream test is a good gauge of productivity in busy offices because it simulates multi-user traffic in a workgroup at busy times during the day. While it may be unlikely that a small workgroup (with three to five users, for example) will generate the kind of traffic simulated by BLI’s job stream, this performance could be a limiting factor to larger workgroups (10 or more users). Note that HP recommends the model for up to 10 users. The mid-size workgroup laser models proved to be stiffer competition for the X576dw, which, when compared against this group, was the fastest in only two tests in default mode, though, notably, it was still faster than average in about half of the tests. Again, job stream results were slower than average—outputting the pages at less than half the average laser speed in black mode. In its fastest mode (General Office Mode, rated speed of 70 ppm), in which it produces output that is acceptable for text or internal documents and for proofing purposes, the Officejet Pro X576dw was the fastest of the mid-size workgroup model group when printing sets of a document, whether single- or double-sided, in black or in color. But readers might be surprised to learn that in copy mode its performance in its fastest mode was not much faster than in the default mode (these results are due in part to the speeds at which the document feeder can scan originals). BLI’s tested copy speeds were faster than average in color and black when making single- or double-sided copies from single-sided originals, but slower than the average when making double-sided copies from double- sided originals. Because of its inkjet technology, it’s not surprising that, based on BLI’s energy consumption testing, the X576dw’s projected annual energy consumption is lower than that of all the BuyersLab.com Reproduced with the written permission of Buyers Laboratory LLC.

WHITE PAPER—Inkjet versus Laser laser models tested in both groups. In fact, its energy consumption is about half that of the laser model with the lowest energy consumption in both the small workgroup and mid-size workgroup categories. In addition, BLI calculates cartridge waste to be the lowest compared to small workgroup models and among the lowest compared to mid-size workgroup models. Its cost per page for supplies is lower than any of the of the small workgroup laser models. While it’s also lower than the average for the mid-size workgroup models, it is nearly 3 cents higher than that of the mid-size workgroup laser model with the lowest cost per page (note, however, that the laser model would require a service contract, which would add to its lifecycle cost; a service contract is not required for the HP model). Finally, when calculating cost of ownership over three years—including the purchase price and all supplies required—BLI found the HP X576dw to be the most affordable choice compared to both groups when printing up to 5,000 pages per month. In conclusion, BLI believes the HP Officejet Pro X576dw will be not only a viable replacement, but in many cases a better choice, than laser models in environments with up to 10 users and monthly volumes up to 5,000 pages. For users with higher monthly volumes, a high proportion of copy output, or where output will often be produced on recycled paper or require the finest lines, laser models will likely be a better choice.

WHITE PAPER—Inkjet versus Laser TEST DATA RELIABILITY PERFORMANCE In terms of reliability, BLI’s testing found that the Officejet Pro X576dw held its own not only against the small workgroup models that HP cites as its chief competitors (based on price), but also against some of the more robust, mid-size workgroup laser models in the same speed range, completing a 37,500-impression durability test with no misfeeds or malfunctions. While a handful of the laser models from both groups experienced one to three misfeeds each in BLI’s testing, most devices completed testing with none.

WHITE PAPER—Inkjet versus Laser A LOOK AT THE HP OFFICEJET PRO X576DW’S THREE MODES: How They Affect Image Quality and Speed The HP Officejet Pro X576dw has three modes, ranging in speed up to 70 ppm in speed, with image quality varying accordingly. Before comparing the unit’s output in default mode to that of laser devices, let’s take a look at how the output differs in each of these modes. IMAGE QUALITY IN HP’S DIFFERENT MODES • In general, as speed increases, quality decreases and vice versa. The default mode of the Officejet Pro X576dw is Professional Mode, which has a rated speed of 42 ppm and is suitable for general business output because it offers mid-range quality at a relatively high speed. The fastest mode, General Office (rated speed, 70 ppm), is the equivalent of a draft mode, however, the quality is much better than would be expected from “draft mode,” as shown in the images below. Presentation Mode (for which HP doesn’t specify the rated speed) is the unit’s best quality mode and the decrease in speed is quite dramatic, though quality improves greatly over the other two modes. Because with inkjet technology, ink is absorbed by the paper used for printing, smoother/glossy papers results in improved output; alternately, rougher papers (such as recycled media) will result in diminished image quality.

WHITE PAPER—Inkjet versus Laser HP Officejet Pro X576dw Output on 22-Lb. Bond GENERAL OFFICE MODE General Office Mode (fastest mode) produced output that was slightly lighter than that produced in the other modes, though fine lines were thicker and showed some jaggedness. PROFESSIONAL MODE Professional Mode (default mode) produced good-quality output, suitable for most business users. PRESENTATION MODE Presentation Mode (best quality mode) showed smoother ink coverage, more realistic skin tones, and more detailed highlights and shadows in images than output produced in the default mode.

WHITE PAPER—Inkjet versus Laser MAGNIFIED FINE LINES • One of the most noticeable improvements when moving up the scale in image quality modes (from General Office to Professional to Presentation) was in the area of fine lines, as depicted in the example below. Lines produced in the fastest mode were thicker and showed some jaggedness. In the default mode, lines were finer and smoother, though they still showed some jittering. In the best quality mode, lines were much smoother, with only slight jittering visible.

WHITE PAPER—Inkjet versus Laser SPEED PERFORMANCE IN HP’S DIFFERENT MODES • Because inkjet technology relies on ejecting more ink through the nozzles in the printhead to print the image and improved quality is a result of laying more ink on the page, speed decreases as quality improves. While copy speeds for outputting one set of a 10-page document are generally the same in General Office Mode and Professional Mode (this is a limitation of the document feeder speed), speeds in Presentation Mode drop significantly. In print mode, there is a much clearer delineation in tested speeds for each mode, as the document feeder is not involved in the process. Tested Color Copy Speed in HP’s Three Modes (1 Set of 10 Pages; In PPM) Color copy speed is tested using a 10-page color document in simplex, 1:2 duplex and 2:2 duplex modes. Timing begins when the start key is pressed and ends when the last page of the document set completely exits the device into the output tray. Tested Color Print Speed in HP’s Three Modes (1 Set of 10 Pages; In PPM) Color print speed is tested using a 10-page color document in simplex and duplex modes. Timing begins when the print button is pressed and ends when the last page of the document set completely exits the device into the output tray.

WHITE PAPER—Inkjet versus Laser HP PRINT QUALITY VS. SMALL WORKGROUP LASER MODELS BLI’s image quality assessment is based on samples output with devices in default mode, using Georgia-Pacific Printing Paper with ColorLok (96 brightness, 22-lb. bond). In addition to a visual observation under a Graphiclite D5000 Standard Viewer, density of black and color output is measured using an X-Rite 500 Series Densitometer. To show the differences in output quality produced by the Officejet Pro X576dw, some samples were also output in the fastest (text) and slowest (images) modes. BLI chose samples from at least two different laser models for each comparison to demonstrate the range of laser output for the class of device. Images shown from tested laser models generally represent typical quality for the competitive class of device. In some cases, additional images were chosen to represent defects found in output for the class (such as the fine lines on dark backgrounds shown on page 22) . • When printed color images were compared, BLI technicians noted that the X576dw produced output in its default Professional Mode that was as good as, if not better than, that of small workgroup laser models tested. Despite lower than average density readings for cyan and magenta, as can be seen in the images on page 21, output from the X576dw showed bright, saturated colors and an above average amount of detail. In Presentation Mode, output from the X576dw was marked by even brighter colors and greater contrast, putting it on par with or, in some cases, even better than, output from many of the laser models. • Fine lines on dark backgrounds and circular lines produced in Professional and Presentation Modes were cleaner and more consistent than those produced by many laser devices tested. However, some laser devices were better at differentiating thicker versus thinner lines. • When printed black text was viewed under magnification, BLI technicians noted that, in spite of lower than average black density readings recorded by BLI’s test instruments, text from the Officejet Pro X576dw’s default Professional Mode nevertheless appeared dark and cleanly formed. Density readings of solid black output printed in Presentation Mode were on par with the average for laser models tested, though density readings for the fastest mode were lower than those for all laser models in the group. • Not surprisingly, color text produced by color laser models was cleaner and smoother than that produced by the Officejet Pro X576dw.

HP COPY QUALITY VS. SMALL WORKGROUP LASER • When copied black text was viewed under magnification, BLI technicians noted that most laser models produced darker output than the HP model’s default mode. Further, copied text from the X576dw had some areas of incomplete fill in the central portion of letters and the edges of text appeared more jagged than output from most laser models when magnified. In addition, density readings in default mode were lower than all laser models in the group. As a result, copied text from most of the laser models appeared darker and cleaner than HP’s text when viewed by the unaided eye. • Color images in copy mode from the X576dw default mode were on par with or better than copied images from laser models tested. Ink coverage was smooth, color saturation was competitive and fine detail was better than average when compared to the group.

WHITE PAPER—Inkjet versus Laser PRODUCTIVITY DEFAULT MODE VS. SMALL WORKGROUP COLOR LASER MFPS In BLI’s productivity testing, the HP Officejet Pro X576dw, as tested in its default Professional Mode, had a great advantage against small workgroup laser models in most tests performed; this is to be expected due to the unit’s higher rated speed (42 ppm compared with an average of 25 ppm for small workgroup devices). PRINT PRODUCTIVITY VS. SMALL WORKGROUP MFPS • When compared with small workgroup models tested, default mode first-print times for the Officejet Pro X576dw were the fastest of the group for all file types tested from ready mode, though the X576dw was slower than average from overnight sleep mode. • When printing multiple sets of a 10-page test document using the default Professional Mode, the Officejet Pro X576dw was again the fastest of the group in all black and color modes tested (simplex and duplex). • When printing BLI’s 19-page job stream test suite, which simulates multi-user traffic in a busy office, the Officejet Pro X576dw was slower than the average for small workgroup laser models tested in black and color. In fact, the X576dw was the slowest of the group in black mode. BLI technicians attribute this in part to the way in which the inkjet unit processes the stream of mixed files; the unit stops and starts between individual files in the test suite.

WHITE PAPER—Inkjet versus Laser TESTED INK/TONER YIELDS VS. SMALL WORKGROUP LASER MFPS • BLI’s yield testing showed that, compared with small workgroup laser models tested, ink yields for the Officejet Pro X576dw were higher than average for all four colors tested. And, in fact, BLI’s tested yield for the black cartridge was the highest of the group by about 1,300 pages. BLI’s Tested Yields vs. Small Workgroup Laser MFPs BLI’s tested yields are based on an average of two cartridges per color, printed from the PCL driver in default mode, using the ISO 24712 toner yield test original.

WHITE PAPER—Inkjet versus Laser USER MAINTENANCE INTERVENTIONS/CONSUMABLE REPLACEMENTS • BLI also evaluated the number of consumables that would need to be installed or changed over the course of printing 60,000 pages on each device. Based on BLI’s yield testing for ink and toner, and the manufacturers’ rated yields for other consumables, we calculate that the Officejet Pro X576dw would require the fewest number of consumables/ interventions when compared to small workgroup laser devices. User Interventions vs. Small Workgroup Laser User interventions calculated based on BLI’s yield tests for ink and toner (based on an average of two cartridges per color, using the ISO 24712 toner yield test original), as well as manufacturer rated yields for other consumable items (drums, developer units, waste containers, etc.). BLI calculated the total number of supply and maintenance items that would be required to output 60,000 pages. Each individual cartridge or maintenance item was counted as one intervention, so the cyan, magenta, yellow and black cartridges each being replaced once would count as four interventions.

WHITE PAPER—Inkjet versus Laser POWER CONSUMPTION VS. SMALL WORKGROUP LASER MFPS • BLI used its proprietary test methods to determine approximate annual power consumption and found, as would be expected of inkjet technology, that the Officejet Pro X576dw consumed significantly less power than the laser models tested. The calculations shown below are based on printing approximately 2,500 impressions per month. The power savings is also translated into estimated CO2 emissions and annual power cost to show the significant environmental and financial advantages of the technology. Power Consumption/CO2 Emissions vs. Small Workgroup Laser MFPs The figures in the graph above represent projected annual energy consumption based on conducting BLI’s Job Stream Matrix test once daily five times per week for an entire year. Included in the projection is the power for the device while in sleep mode, weekdays and over the weekend. Based on 30,096 impressions per year—actual usage may vary. *CO2 emissions are based on the U.S. Environmental Protection Agency’s Climate Change Action Plan emission factor for 2009.
