Custom size papers HP 8850
Would somebody please tell me how to get custom paper sizes (not types of paper) into the HP 8850? I seem to have tried everything under the sun, though I suppose I must be doing something wrong! Sometimes a size that I choose somehow gets into the list; sometimes it doesn't; sometimes it even disappears! Sometimes I see it in one the lists but not on the Automatisation Proprint list. I'm using Photoshop 7.
ps HP doesn't give much information, I feel, except the obvious!
