I had trouble printing PDFs with evince (fixed by Evince does not show printers) and in the meantime used lpr successfully to do things.
I found several options in the man page (page-ranges, number-up) but none to specify the paper source. In the print dialog I can chose between Tray 1 and Multipurpose Feeder.
Is it possible (and if so, how?) to choose the paper source when printing from the command line with lpr?
