I cant print on a envelope

Does the envelop go through and come out blank? Does the envelope jam? Does it just sit in the manual feed tray forever while the printer does nothing?

Unless it was the print driver you updated, the problem is most likely in the application that is trying to print to the printer. You should always keep track of what you update. If you don't know what you're updating, how is anyone else supposed to know. There are ways to determine what was last installed, but it's an effort.

When printing envelopes, it is sometime difficult to know which way to feed the envelope. Check the print settings. If the printer does nothing, check your cable connections.
