Paper mismatch

you have to load the printer driver for HP Deskjet 990c. This worked for me perfectly and I'm sitting here printing my wedding invites right now! Good luck!

Hi kingwa55,

I have an hp photosmart c4480 and was having the same problem printing wedding invitations. Same size 5.5"x8.5'. Im not sure if this will work on your printer, but this is what I had to do.

Click on Print, then Properties, then features.
About half way down there is a drop down box under sizing options.
Click on custom
Create a name, and put your width and height in.
Click Save and then OK
Completely X out of the print options.
Then Click
File, print, properties,features, click the drop down box under sizing options.
Click more and scroll to the bottom and it should be there.

If your options are different then mine, I'm sorry for wasting your time.

Yes!!! I have a HP C4480 also and I had the same problem with my wedding invitation cards but I follow the instructions from number #2 and guess what , I did it. My invitations were size 5.25 x 7.75, they looked great, So thank you for your help.

This is a definitive solution for such problems.
You have to select in printing options -> paper type -> OTHER

hp printer has the ability to detect the quality of the paper, and hp developped its own standards for envelops and cards I suppose to encourage users to buy their paper products.
