HP2600N Using Too Much Toner

For some reason, my printouts look extremely dark. Especially when compared to MS Window's printouts.

When I use Linux, the printouts look as if the printer is just dumping toner.

I've played with several settings, but the only setting that helps is setting the "Print Quality" to "Draft Mode" instead of using "Normal Mode". It is so bad, "Normal Mode" creates printouts with bleeding colors.

"Draft Mode" seems better, but lacks color saturation. Blues look really black. "Normal Mode" provides some color with blues, but it's a really dark blue.

(Using the latest download and deleted the existing cups printer entries and then let cups recreate the printer entries for kicks.)

Also, setting to Bits Per Plane to "1 BPP" instead of "2 BPP" for color helps. Using "2 BPP" for color, creates printouts with bleeding colors also.

(*Note: colors look extremely similar, if not the same when using 1BPP or 2BPP now... quite an improvement.)

So. Two things.

1) Set to Print Quality to "Draft Mode" for both Monochrome & Color printer profiles.

2) Set Bits Per Plane for Color to "1 BPP". (Monochrome only printouts seem to be just fine when using "2 BPP" -- no bleeding of the toner through the paper when only monochrome.)

Only use "1-bpp" for color, the default. "2-bpp" is uncorrected. Unless you have read "CUSTOM ICC/ICM COLOR PRINTER PROFILE" in the INSTALL file.

Thanks for confirming. I don't know much about ICC(, but do realize they're necessary for printing photographs, etc).

I do have to use quality=draft mode for printing also for preventing my hp2600n from using *way* too much toner for both monochrome & color. (It's almost as if the printer thinks it's trying to print "photo quality" with the amount of toner it's using.)

One minor note, a comparison between WindowsXP and Linux/CUPS (using default ICM) printout shows the WindowsXP printout with much lighter colors then the Linux/CUPS printout. I'm assuming this minor issue is pretty much already known.
