I have Samsung ML-1915 laser printer. It works with Samsung's "universal printer driver". Some applications allow to set "printer language" option in printer settings (PDF or postscript). When "pdf" (default) is selected the printer doesn't print in landscape orientation (all prints are portrait - doesn't matter what is set in printer options; some parts of print are out of paper). When "PostScript" is set - the printer works properly with both paper orientations. Unfortunately some applications (e.g. Firefox) do not allow to set this option (it isn't present in dialog window). Where can I set printer language for all application as default setting?
