If you cannot print from Revit but you can print from other Autodesk applications like AutoCAD the reason is because Revit prints using the default window printer. Do the following to verify its not an issue with Revit:
Within Revit print to a PDF. Revit doesn't come with a PDF driver so you will either have to use the Adobe PDF driver or one that is known to work well with Revit is the CutePDF driver.
If you can print a PDF then you will need your IT personnel to log into your machine as administrator to remove your network print driver and install the printers window driver. For example if your printer is an HP KIP driver then you will need to find the HP KIP window driver.
