can't add a printer in Print & Fax preference
I was having trouble with my printer resource for my HP Laserjet 6MP, which had been working fine until this week. In print preferences, I deleted the printer, and another one for good measure. When I went to add new printer, there were no printers to choose from. I reset the printer resource (many times!) restarted the computer (many times!) turned off and on the printer a few times, tried everything again, but still no printers to choose from.
I downloaded the printer resource from this website, http://support.apple.com/kb/DL907and tried everything again, all the steps I tried before. Still no luck.
I think the Print & Fax preference might be trashed. How do I replace that?
I should add that I am not using the printer on a network, but directly from my USB. I am networked only through wifi to my internet modem. I know 10.6.8 sometimes has network connectivity issues with printers, but I'm not sure that's the cause of this, as I have been on 10.6.8 for awhile.
Thanks in advance for any advice. You rock!
