Firstly, I have no parallel port on my tiny motherboard. Then my System identifies the printer after "sudo lsusb" as Lexmark Optra E312, which could be correct. And indeed I remember that before smashing CUPS I sometimes had the same problem. the .ps files are printed via command-line. furthermore, as I am not exactly a proper device-tester, I changed the "driver" from *PCL-5 Printer CUPS+Gutenprint* to a *PCL-5 Printer Foomatic* both provided by the OS itself. And it appears running better. I want to go on printing a bit more before crowing. What do You think? could the origin of the mistakes be in one of these "drivers"? Has anyone the same or similar printer?
