My printer, Brother HL-2040, does not accept print-jobs out of a C-program. It works, however, perfectly on the lpr-command, with office applications and emacs. System: openSuse Linux 13.1 Compiler: GNU C-compiler 4.8-2.1.2 Driver: Brother HL-2060-CUPS+Gutenprint v5.2.9 Options: Locale, Remote, Use as Default, Accept Print jobs, Enable printing The printer can be opened as a file, but it does not react on the "putc" command nor on fprintf. Printer status: ready, printing que emty; What can be done? Best regards J. Bucher
