http://www.linuxquestions.org – I have 75 iterations of the same job and want to get rid om them. I used to be able to find a printer queue sub-windsw but can't find it now. Have tried with Kubuntu 12.04, 12.10,and 13.10. Printer HPLJ 3330. I don't think it's the LJ--I left it unplugged from house current for two days and nothing went away. (HowTos)
