Print margin problems in Ubuntu 12.10
Printer is HP 5515, paper size A4. Using the hpcups 3.12.6 driver, the printing is misaligned
at the top of the page; the margins are not set correctly. On earlier versions of Linux I was able to switch to the hpijs driver, and it worked correctly.
Now the hpijs driver doesn't work at all; it prints "Unable to open the initial device, quitting.".
Both these problems seem to have been around for some years, judging by queries on the net...
A solution to either problem would be welcome.
