Unable to print envelope from rear slot

"Here is the problem:

Printer paper type (Printer's native envelope setting) must match Printee paper type (Microsoft Word). The unfortunate design of Microsoft Word's print envelop feature does not set this correctly.

What I would do (unfortunately) is add an extra step.

Print the envelop to XPS format or PDF format (I use cutePDF).

(set these as your default printer).

Then when you print from the XPS or PDF, set the paper type and tray type. You will then print without that annoying error.

At least this worked for me. Good Luck."

Neither of the above solutions helped me but finding out it was a problem in the WORD envelope settings gave me an idea. I created a regular WORD doc with the paper size, margins etc that I wanted for my envelope and then printed it using the XP 15000 envelope settings. I was only doing return adresses so every envelope was the same. Interestingly I did labels yesterday with no problem at all once I found out from anoter internet search to override the cd/dvd settings in the Page Setup on the print menu. Maybe mail merge doesn’t have the problem.

After choosing "Envelope" as Paper Type, go back to that menu and choose the last item, "More Paper Sizes..." That will bring up a new dialog box, and you'll see that for some reason, Word sets the paper source for the first page of envelopes to CD/DVD Tray. Change it to Rear Paper Feed Slot, and you should be good to go.
