Comment 10 for bug 994924

First I do not own a printer requiring a plug-in so I can not test anything here. Also the plug-in is not part of hplip and thus not officially supported, but maybe we can find the problem. Can you please attach the output of hp-check.

Can you try to install the plug-in manually without hp-setup by downloading it from http://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/ and check if the manual installation succeeds.
