Linux - Wireless Printing Instructions:

To print wirelessly, the document to be printed must be saved in PDF format.

PDF Creation Instructions for Linux:

Most Linux software allows you to print to a PostScript file and save that file as a PDF:
If you run "ps2pdf", (which is included in most distributions, but can be obtained from here)
then print to a PostScript file and save as a PDF file.

Alternately, create a PDF file from your PostScript file by using the web form at ps2pdf.com.

Upload your saved PDF to the printer of your choosing at the wireless printing page.
