Xerox’s announcement on September 24^th, 2007, may have some customers taking a look at Solid Ink technology for their color business printing requirements. We hope customers take a close look at the technology, and the history of Solid Ink vs. Color Laser or business-focused inkjet devices and make an informed decision about which technologies are the best.

It’s important to consider that Xerox acquired Solid Ink technology when they purchased Tektronix in January of 2000. In the 1980’s, Solid Ink printers had captured an early niche in the graphics departments as proofing devices. Graphic artists liked the 11”X17” format and glossy, vibrant colors that solid ink offered. And, at the time, the nascent inkjet technology business was just emerging. Inkjet was delivering only 180 dpi on special paper. Color laser printers were not commercially feasible back then. We dreamed of someday selling a Color LaserJet printer for $1,000. Today, of course, the technology is much less expensive—HP Color LaserJet printers start at just $299.

But as the technology matured and color printing spread into other parts of the office, color laser became the dominant technology of choice. There were significant differences in the needs of the office users vs. the graphics department. (hp also has strong offerings for the Graphic Arts). Office users needed permanent output that could be handled, copied, annotated and archived. Permanence was especially important in contracts, legal documents, purchase agreements, proposals, etc. Solid Ink technology could not match color laser/dry toner technology in these areas. Also, color laser technology was able to deliver sharper text quality which was also critical in high-value business documents.

General office users also needed fast output. Again, Solid Ink technology had some drawbacks compared to color laser, many of which are documented in this side by side comparison. If a Solid Ink device is turned off, or if nozzles clog, there is up to a 12.5 minute delay to cycle the printer. A color laser printer can be power cycled in less than two minutes. This was another key advantage for color laser.

I’m always fascinated by how some printer manufacturers try to reduce their device performance to specifications produced in some sort of test laboratory. Like automobile MPG (miles per gallon specs). When you get on the road, you can never get the gas mileage rating that was specified for your car. Printer specifications can also be difficult to compare because actual print speed and “rated” print speed are not always the same thing. You know the auto industry clause--“your mileage may vary”.

The printer spec.s of choice for printer vendors include dots per inch (dpi), cost per page (cpp, based on x% page coverage) and pages per minute (ppm). While this can help in device comparisons prior to purchase, the important numbers are really those you experience when you actually are using the devices on the job. Here is a little industry secret--most vendors don’t want you to ask questions about that, let alone benchmark or compare their PQ or performance with other vendors. They shudder at the thought! Let me tell you why.

I’ve blogged on the realities around Laser print quality (dpi) in “Laser Printer Print Quality: The Real Story” and how to better understand printer operating costs in “HP LaserJet Printers and Cost of Ownership.” Now, I want to turn the discussion to understanding actual print speeds in printing real documents on the job--which is more realistic than just looking at ppm. The analogy is similar to cars once again (we even call ppm, “engine speed”). Cubic inches and horsepower will get you part of the way to telling the car's potential for speed and performance. But the real speed spec is 0-60 mph. When I looked for my car, I compared several brands. Although the engines were the same size (3.5L), their acceleration performance varied widely.

Here are some factoids about typical office printing. The typical print job is up to 4 pages long, with about 60% of jobs being 5 pages or less. As you might have guessed, most print jobs (90%) are done in the 10 hour period between 8am and 6pm. 60% of laser printing devices print about 10 jobs, spaced pretty evenly throughout the work-day. Given this typical pattern, chances are that your print jobs are initiated from your devices in stand-by (or sleep) mode—for HP LaserJets this is called “powersave mode.”

From powersave mode, the first page from an HP LaserJet P2015 prints in about 9 seconds, which is over twice as fast as from competing products from Kyocera, Lexmark, Dell or Samsung. This holds true for the second, third, fourth, and fifth pages—so the total realized print times are actually 2X faster for the HP LaserJet than those claiming similar ppm. In fact, you can get your typical job (5 pages) out and finished before some other devices even get started. You can see similar results for other HP LaserJet models in this independent print speed study by QualityLogic.

These faster “typical job” print times are delivered by HP Instant-on Technology. Essentially, “Instant-on” is delivered by cutting-edge fuser technology which you can explore in greater detail in this video. In addition, the HP powersave mode actually saves energy costs. For example, the HP LaserJet P2015 uses less than half as much electricity to operate than comparable Lexmark, Brother, Samsung or Dell models.

While you’ll draw your own conclusions on speed and costs, one thing to consider is that, the faster and more “green” your printing devices, the more satisfied your users and facility managers will be. And you’ll likely get fewer calls to the Help Desk from users trying to print jobs out on a deadline. If you have any stories in this regard, feel free to include them in a comment to me below . . .
