Hi Pascal, thanks for your help. I tried printing from an installed kubuntu dapper. Following your instructions, this is what I've tested so far:
Scenario 1a): Using the recommended HL-5150D Foomatic/Postscript driver with "Double-Sided Printing" set to "Long Edge (Standard)" via the system settings. Scenario 1b): Using the recommended HL-5150D Foomatic/Postscript driver with "Double-Sided Printing" set to "Off" via the system settings. Scenario 2a): Using the Brother HL-5150D BR-Script3 driver with "Duplex" set to "DuplexNoTumble" via the system settings. Scenario 2b): Using the Brother HL-5150D BR-Script3 driver with "Duplex" set to "None" via the system settings. Test results: CUPS Printer Test Page: 1a) -> OK 1b) -> OK 2a) -> OK 2b) -> OK Printing of a pdf file (2 pages): kpdf with "Duplex: long side" 1a) -> printer error 1b) -> printer error 2a) -> printer error 2b) -> printer error kpdf with "Duplex: short side" 1a) -> printer error 1b) -> printer error 2a) -> printer error 2b) -> printer error kpdf with "Duplex: off" 1a) -> printer error 1b) -> printer error 2a) -> prints, but no duplex 2b) -> prints, but no duplex xpdf: "Print" -> "Print with command: lpr" 1a) -> printer error 1b) -> prints, but no duplex 2a) -> printer error 2b) -> prints, but no duplex gv: "Print all" -> "Print command: lpr" 1a) -> perfect duplex printout 1b) -> perfect duplex printout 2a) -> perfect duplex printout 2b) -> perfect duplex printout "lp -o sides=two-sided-long-edge cups-test2.pdf" 1a) -> printer error 1b) -> printer error 2a) -> printer error 2b) -> printer error "lp -o Duplex=DuplexNoTumble cups-test2.pdf" 1a) -> printer error 1b) -> printer error 2a) -> printer error 2b) -> printer error "lpr cups-test2.pdf" 1a) -> printer error 1b) -> prints, but no duplex 2a) -> printer error 2b) -> prints, but no duplex Printing of a html page (2 pages): firefox: No duplex option available 1a) -> printer error 1b) -> prints, but no duplex 2a) -> prints "ERROR NAME; undefinde COMMAND; unable OPERAND STACK;" 2b) -> prints "ERROR NAME; undefinde COMMAND; unable OPERAND STACK;" konquerer with "Duplex: long side" 1a) -> perfect duplex printout 1b) -> prints, but no duplex 2a) -> perfect duplex printout 2b) -> prints, but no duplex Every time the printing fails, the printer indicates a paper-related error via blinking LEDs.
