I own a HP Color LaserJet 2600n which is plugged directly into my Mac Pro running Mac OS 10.6.8. It has worked fine for me for many years.
Last week I tried printing and the results were terrible - most all of the places where there would usually be colors printed mostly black instead (see attached).
I ran a self test on the printer and the colors came out perfect, so I've come to the conclusion that the problem is in the communications between my Mac and the printer.
The HP driver I'm using is 1.4.0 and the firmware is 20050610.
I went HP's site for downloading drivers and firmware (here) and saw that there is a firmware upgrade - 20120928. I downloaded this and have tried several times to get it to open, but I keep getting a dialog box that states "HP Firmware Upgrade Utility quit unexpectedly"
I assume that the upgrade utility is either fighting with another program or with the operating system itself. And, even if I get it installed correctly, I'm not sure that it will solve my printing problem.
Can you help me? Thank you!
Thanks so much for your reply. I'm happy to wait.
Yes, please - I still need help.
Are you using genuine HP cartridges? Or generic/refilled ones?
Please click the "Reply to expert" button below to let me know.Thank you.
Generic (although I've been using generic/refilled ones in this since I bought it).
Also - when I ran a self-printing test on the HP printer (using the printer's control panel), the test came back flawless.
No - sorry, I wasn't clear. All the cartridges in the printer are refilled ones. I've been replacing the cartridges with refilled ones since I bought the printer and replaced the original ones.
Here's a .pdf of a scanned test print I just performed (please let me know if you can't open it).
Yes - I upgraded from 10.5 to 10.6 at least 18 months ago without any subsequent change in the HP printer quality.
HP did have an upgrade for this printer for Mac OS 10.6 (click here).
I've downloaded it but when I go to install it, I receive this message (see below).
Thanks, XXXXX XXXXX will be great - I appreciate your help.
I'm not clear on the function of firmware - wouldn't it help the computer talk to the printer?
Anyway, thanks again.
Thank you for the suggestion but it did not work. I've even tried several different USB ports with no success.
I checked with Apple and see that HP updated their drivers recently (click here). I reinstalled the drivers and see from Apple's site (here) that I am running the correct one (1.4.0) for my printer. I then replicated the process you suggested above however I am still having the same problems.
Any other ideas?
John - great idea!
I have a MacBook Pro laptop and hooked it up to the HP Color Laserjet 2600n printer ang got the same results!!
The laptop is also running Mac OS 10.6.8 and used the 1.4.0 driver for the printer (the same OS and driver as the MacPro is using).
I was also able to get HP's firmware update to load through the laptop so the printer is now using the newer firmware.
Sounds like a driver problem?
I have an old Dell laptop running Windows XP. I hooked the 2600n up to it this morning and it printed beautifully.
So... seems to be a problem with the Macs?
