Having problems printing to envelopes. Using Windows 7 Pro on a desktop PC,
MS Office Word 2007. Printer HP Photosmart 7520
(Can print labels but not envelopes)
1) Opening MS Word document, click on Mailings
2) Envelopes, shows mailing address (from document) or I add it in and also return address
4)Envelope Options- Standard #10 envelope (4 1/8 x 9 1/2 inches), Fonts Auto, Face Up, Automatically select feed, clockwise rotation (Had reset Options prior to above)
5) Click Print... and can here printer working and envelope fed (or using a test blank paper to see if it prints), but nothing is printed.

Any help will be appreciated,

Thanks Sy
