my printer (hp officejet pro L7590) has the same problem when printing in "draft" mode; my version of hplip is 3.9.8 on kubuntu 9.04 in my terminal the command hp-check -t returns HP Linux Imaging and Printing System (ver. 3.9.8) Dependency/Version Check Utility ver. 14.3 Copyright (c) 2001-9 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to distribute it under certain conditions. See COPYING file for more details. Note: hp-check can be run in three modes: 1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile HPLIP. 2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run. 3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).
