Please try the newest version of HPLIP (1.7.3) from upstream: http://hplip.sourceforge.net/
There is a completely automatic installer avaiolable (self-extracting archive) which automatically installs everything needed from the internet and afterwards uninstalls your old HPLIP and replaces it by the current version. HP has tested it on many distributions including Dapper. After that remove and recreate your print queues. Does this help? ** Changed in: hplip (Ubuntu) Target: None => dapper-updates ** Summary changed: - CUPS 1.2.0 disabled by ServerName in client.conf + Dapper needs Fax-capable HPLIP version -- Dapper needs Fax-capable HPLIP version https://launchpad.net/bugs/48387 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
