I emerged cups-1.1.18, gimp-print-4.2.4 and gimp-print-cups-4.3.5. I have an HP DeskJet 845C USB printer and it wasn't recognised, even after reboot. I used the CUPS web interface and KDE Print Manager, using first USB printer port. In both cases the test print failed to materialise. Even my already configured hpijs setup failed to print. I have now unmerged them all and remerged cups-1.1017_pre20021025 and gimp-print-cups-4.3.0-r2 and I can print again
have u re-emerged ghostview after cups as i wrote?
As you wrote where? I can't see that in your mail message. No, I didn't re-emerge ghostview - I'll try again later.
OK, I remerged and saw the message about ghostscript at the end of the cups emerge - it's easy to miss that when you're emerging multiple packages - perhaps a message at the start of cups emerge with user aknowledgement required would be better? After ghostview is emerged it all works fine.
