To print on a Unix machine, you can use the command lpr at the Unix command line. For example, to print the file myfile.ps in duplex on dilbert, simply type lpr -P< printername >   -Zduplex myfile.ps. < printername >   is the name of the printer (e.g. gc332csiplpr). For more information, type man lpr at the Unix command line, or check out the survival guide. Note, there are problems printing postscript and PDF files from UNIX. Hopefully, this will be fixed after the move to Centergy.
