I followed the directions from the site below to a "T" and the printer still gives the "wrong paper size error message and prints nothing. I even made sure that Envelope # 10 was selected in the control panel printer preferences and in Word and still no luck. Help. Thanks

Re: Printing single envelopes on an Officejet Pro 8600

Today, I had occasion to print an envelope for the first time on my new Officejet Pro 8600 Plus. It's a classic tale, where the hero struggles but comes out OK in the end.
For the first time, I noticed there's no manual feed.
So my procedure (Windows Vista) is this:
1. Replace tray paper with one envelope.
2. Adjust vertical and horizontal paper sizer-holder sliders in tray. (I missed the longitudinal slider the first time, which created a wrong-size error.)
3. Change printer settings! Go to Printer preferences -> Paper/Quality tab -> Paper size, and choose the appropriate setting. (E.g. Envelope #10)
4. And then print using MS Word's envelope wizard.
More hoops than I expected. But the print was pretty good, with only mild envelope bending
