C6380 - How do I print 4 photos on an A4 page (so each is 6x4)?

Hello,

I am using Ubuntu 9.04 with HPLIP 3.9.2 (the one that comes with 9.04) and an HP Photosmart C6380.

We have been printing to 6x4 paper without much difficulty (although admittedly more than printing from the HP software for Windows).

We are trying to print four (roughly 6x4) photos per A4 page - we bought the A4 pages because it is much cheaper than buying the pre-cut 6x4 paper. I cannot figure out any settings that make it do this. Even if I set the "N-up" setting to do 4 per page, it sends the four photos to the printer as four separate jobs and prints each on its own page. They don't seem to be taking up the full A4 page, but they are more like 2/3s than a quarter.

I would have thought this was a fairly common thing to want to do with a photo printer.

Any help would be appreciated, I am really impressed by HP's Gnu/Linux support (it is why we bought an HP)!
