Photoshop wont print

I have a 13" MacBook running 10.6.8. It has Adobe CS 5.1 installed and Photoshop will not print.

I have tested the printers and they will print test pages and from other applications.

I did try updating the driver but it didn't work.

It is not just one printer. None of them will print.

I checked for Adobe updates and there weren't any for Photoshop.

I CAN print from other Adobe applications.

I restarted the computer

I rest the PRAM

The person who uses this laptop said that she printed from photoshop last night and now its not working.

Any thoughts on how to fix this?

Thank you!
