Have you ever tried to print an 11' x 17" document at the library only to have it come out like this? To print 11"x17", you have to choose the OG-ML-Copier. What??? You say that printer is not in your default printers? If not, you can add it by the following method:
Go to Start - Devices and Printers - Add a printer
Click on "Add a network printer"
Click on "The printer that I want isn't listed" (don't you hate that?)
With the radio button clicked for "Select a shared printer by name", type "\\ps\" and you will see a list of printers. Scroll down and click on \\ps\OG-ML-COPIER.
If this makes your head spin, head on over to the Reference desk and they will be glad to do it for you!
