Just read Mobius Strip's 9th December post and thread 1889763 on the subject of greyed out paper types but only after two days of faffing around in frustration myself. I am on Snow Leopard and have just replaced a printer with an HP CC335 (also known as a C309a). Same problem. I get a full range of papers in Pages application but in Photshop CS4 there are only a couple of inkjet and photo papers and all the other media types and sub menus are greyed. I did not initally install any drivers from HP or the printer's CD as I had read the HP warning at:

A short time after setting up the printer there was a driver update to 2.3 which happened through the Apple software auto update although I still see v 2.2.1 when I loook in 'about this mac.' Someone on Apple's forum noted that HP had released v2.3 drivers a couple of days ago so I downloaded and installed them from HP yesterday. I still only see v2.2.1 and of course none of this has cured the problem.
As the printer is only a couple of weeks old I will have return it unless there is a solution. If it would work I'd keep it as it duplexes and faxes as well as scan and print.
Is there a solution?
If not, can anyone recommend a good all-in-one that will function properly with photoshop?
