Help!! HP DeskJet 6980 NOT printing all fonts

[princessbucki]

Hi
One of my printers has stopped printing some of its fonts, for example if I do a document and include the following fonts: Times New Roman, Calibri, Tahoma, Arial, Gill Sans MT and Bradley, only Times New Roman, Tahoma and Arial will print out. I've been tearing my hair about over this problem for the last week and have done many searches but haven't managed to find a solution.

Has anyone else come across this? Any help/advice would be very gratefully received.

Cheers
Kirsty
