Acrobat 9.4.2 Update Causes Printing Problems

After updating to Acrobat 9.4.2, one of the following occurs when you print to a printer from Acrobat:

• Error: "Before you can perform print-related tasks such as page setup or printing a document, you need to install a printer."
• Nothing happens when you click OK in the Print dialog box. For example, no progress bar appears and nothing is printed.

Adobe has released a files called "AcrobatPatchApplication.exe" to fix the issue. You may download and run from here.
