    Why does my old HP 6L print images better than my newer HP laserjets?

    Yes, it is possible. "Diffusion Dither" is the Floyd-Steinberg one. There are 3 other built-in methods, or you can create a custom one:

    Why does my old HP 6L print images better than my newer HP laserjets?

    Your HP 6L appears to be printing halftones using the Floyd-Steinberg dithering algorithm (https://en.wikipedia.org/wiki/Floyd–Steinberg_dithering), which is arguably the best one for the job. HP M28w, however, uses a generic dotted halftones pattern. The difference is caused by the printer...

    Best place to buy QY6-0084 print head for Canon Pro 100

    The answer is simple enough: it has happened to me. Keep in mind that there are many aftermarket inks, and not all of them are equal; some are worse than others in that regard.

    Best place to buy QY6-0084 print head for Canon Pro 100

    That may sound counterintuitive, but Craigslist would be the best place. A lightly used Pixma Pro-100 sells for US$150, plus or minus, often with carts and even some extra paper. Anything significantly more is a rip off. Just get a whole thing, but insist on testing it first, even if you just...

    Salvaging Canon Pixma Pro-100 - which parts to keep?

    That's the main problem for me at this point--to know how to take it apart :) Could not find any info online.

    Salvaging Canon Pixma Pro-100 - which parts to keep?

    The printer is practically new, yet pretty much dead and out of warranty. I got another working one, the same model. Want to get rid of the dead one, although I would like to know which parts are worth saving. The carts, the printhead, what else? Thanks!

    Click Bait Messages Via Private Messaging

    Just an idea: You may want to start thinking about how to prevent the ongoing data harvesting on your site. To clarify, I received a sex spam PM immediately when I logged in after some weeks of absence. That meant that some bot was monitoring the user activity on this site, and there was no...

    Pixma Pro-100 - error 5100 on startup

    No. The strip is immaculate. Plus, some dirt/grease on it would not cause such behavior. It is like the strip is not being read at all.

    Pixma Pro-100 - error 5100 on startup

    Thank you, but you're stating the obvious. It is no longer under warranty, and it broke before my very eyes: it printed fine and then suddenly quit. The behavior is the same, if I remove the carts completely.

    Pixma Pro-100 - error 5100 on startup

    The printer fails to position the printhead, causing a 5100 error. The timing strip is pristine and has been wiped with isopropyl alcohol as a precaution, yet that did not help. The behavior is the same if the carts are removed. The printer is practically new, with less than 50 printouts and...
