I am running Ubuntu 12.04 on an LTSP network.
I have attached a printer to the server via USB.
The printer is an HP LaserJet Pro P1102 with driver Foomatic/foo2zjs-z2 (recommended).
Often the printer goes to sleep, and then jobs submitted do not get printed. Even when the printer is turned on to force waking.
How can I wake up the printer so the print jobs will be executed?
