I don't see any problems in the error_log. This could be a problem with the parallel port, does the command dmesg give any errors related to lp0 after trying to print?
You could try the following basic test: 1) Create a test.pnm image with e.g. the GIMP. 2) Run the following command (as root): $ sudo -i # pnm2ppa -v 712 -B 2 -t 10 -b 150 -l 10 -r 10 -x 160 -y 50 -i test.pnm -o - > /dev/lp0 Does this print the image? -- Hp 712c does not physically print https://launchpad.net/bugs/57801 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
