Printing
From CollabLandWiki
Here's how to make the RCDC Color Laser printers automagically duplex (print on both sides of the page) for you:
1 - In the print options box, choose the Color Laser as your printer and
hit the 'Properties' button
2 - Click on the 'Printing Shortcuts' tab and select 'Two-sided (Duplex)
Printing'. Click the 'OK' button.
3 - Release your print job from the GoPrint station. All done!
If it doesn't work, it means that I need to manually enable the duplexing
on that machine's print driver - so let me know which machine is cranky.
