CAN'T PRINT A9 ENVELOPES ON HP OFFICEJET PRO 8720

[LYNN18]

How do I print size A9 envelopes on my printer?  This is a very common size for greeting cards.

Hi @LYNN18,

Welcome to the HP Forums!

Thank you for posting your query on this forum, it's a great place to find answers.

I reviewed your post and I understand that you are having issues printing A9 envelopes.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you create a custom size envelope to print the A9 envelopes. Follow the steps in the below article to create a custom paper size.

Using the Hallmark software you will need to change the envelope size to Single-Fold 162mm x 229mm C5.  You may have to adjust where you type the "send to" address but it will pull it through the feeder and print it.  I moved the address down just a little and it worked.  If you don't get it right the first time make another adjustment and try again.  It looks like we have to change it each time we print an envelope but I can do that until I figure out something in the set-up.  I'm just tickled that it's printing because I send a lot of cards.  

I contacted Hallmark and they asked me if the error message was on the computer or the printer.  It read paper mismatch on the printer so they said it wasn't a software problem.  Earlier HP told me it was an app (Hallmark) problem.

If its a driver issue I wish HP would provide a driver for the single-fold A9 envelope for the HP 8720.
