Samsung's cheap ML-1510 USB Laser Printer cannot print with the default ghostscript installation (ghostscript-gnu) but can with the ghostscript-esp implementation. The printing using the gnu implementation appears to work but the output does not appear on the printer ; no errors are reported ; the printer does not wake up if it is in sleep mode. Reproducible : 100% (also reported with ML-1210) Fix : emerge -C ghostscript-gnu ; emerge ghostscript-esp Information: This is from the CUPS error log with debugging set to info. I *suspect* the cause of the problem is the -sDevice=gdi line, though this is not reported as an error. gdi is not listed as a possible device on the help information for foomatic-gswrapper for ghostscript-gnu, but is for ghostscript-esp. I presume this failure is sending the rendered output into a data black hole.

Please use ghostscript-gpl or gs-esp. gs-gnu is lacking behind a lot.
ghostscript-gpl doesn't work with foomatic drivers, i still say that cups should require ghostscript-esp... AFAIR, most drivers are GDI based.
