I am using SuSE 10.2 and an HP Officejet 5510 printer.

The printer prints but it prints faded!

I installed new toners so the toners are not the problem, it prints fine when I boot it up in windows.

I've searched up and down trying to figure out it's the driver, or an application but I can't find any clues.

If anyone that has seen this prooblem before and can point me in the right direction I'll greatly appreciate it.

It's probably in the printer setup (the ppd file in /etc/cups/ppd). You may have a line that reads "DefaultResolution 300dpi'. Change it to 600dpi.

Or, use the cups printer setup tool to go through the settings and set the resolution. 300dpi is draft mode; 600dpi is quality mode.

Hint: you can use that printer setup tool to define several logical printers for one physical printer. Set up print quality (draft, quality, photo, greyscale, color, portrait, landscape, etc) for printing tasks you typically run. It saves time by not having to go into printer setup for each print job by having pre-defined printers to choose from for the task at hand.

Thank you, sensei, it worked!!!!!

I used the web interface http://localhost:631 of CUPS to change the "DefaultResolution" and changed the resolution to 600dpi on both color and black cartridges. I didnt know I could create my own configs on a logical printer so I could just pick a printer on the fly instead of manually changing the configuration for every scenario. Thanks for the help, it's a neat trick!!
