When printing from Acrobat 9 Pro to a LaserJet 4250 using the Postscript driver, the printer waits several minutes on "Processing Job". This is a two page scanned document that someone used the Typerwriter feature to mark up. I power cycled the printer, installed the latest PS driver, no dice. I switched to the PCL driver, and the document printed immediately.
In the interest of convenience for the user, I didn't test print other documents with the PS driver, but I am able to print this document to another PS printer - a Savin C4540.
Why is the PS driver hanging up? How can I fix it?
