I have a G5 running 10.5.8. MacBook Pro running 10.6.7 which I also ran Software Update on yesterday morning. I can boot the MBP to Win XP as well. I have an EPSON Stylus Photo 1270 hooked to a USB hub. I have been happily printing from the G5 and the MBP from Mac or Win happily for two years.
Suddenly I can no longer print from the MBP from either Mac or Win. When attempting from Mac the job goes to the print cue and then tosses the error "On Hold (Authentication Required). I have searched and searched. I have deleted and added the printer on both systems. I have updated Bonjour on Win XP. I have reset sharing settings, I have unplugged the printer, I have access the CUPS utility at localhost:631 and tried to customize the settings, I ran Software Update on the G5.
Through all of this, absolutely nothing has improved.
I have scoured the Apple discussions and tried everything I can find there as well.
Can anyone assist in conquering this beast? Most importantly, Invoicing and payment is now at a standstill as I cannot print from the MBP Win where Quickbooks is running.
