Printing problems after applying the Acrobat 9.4.2 update? There’s a fix
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 the OK button in the Print dialog. For example, no progress bar appears and nothing is printed.
