Officejet Pro K550 text prints grey instead of black

Try updating the printer driver. If that fails, then this problem may be mechanical in nature.

I also have the OfficeJet 6500 and had the same problem. The black text was printing using a mix of colored inks instead of the black ink, resulting in a grey, fuzzy text. I finally found a solution. In each application under Page Setup, there is an option called "Format for". Mine had been set to "Any Printer". I changed that to "Officejet 6500 E709n [830E4A]" and now it prints the black just fine. I have a Mac running 10.4.11. Hope this helps.

Try to replace the the black print head.

this sounds like, for this model, more like an os issue....try to remove and then reinstall the printer...

you have to check the ink levels in your cartridge. if they ae low then replace the color cartridges.

You could try using these drivers on the Hp.com. These drivers were from March of 2007.

This was listed at Officejet K550. They didn't have a Pro Printer listed. If there are any letters after the model number you should go to that page instead.
