Hi You not say what windows version you are using, got a XP driver for you.

You can download a driver Software from my website then you can use the driver to set your printer up.
Just click on this link and it will download for you, and it is best to save it on your desktop so you can find it easy.
This is for the HP-Photosmart-7450-XP-32Bit

I don't have a solution; I have exactly the same problem, only print from a Mac (Snow Leopard) to Photosmart C4580 on Avery name tents (8 1/2 x 11 stock).
Prints find on plain paper - lines up perfectly. Insert name tent stock, make no adjustment to print settings, and suddenly the text is printing in a different location on the page.
