Dear Aaron

I did as you suggested and downloaded all the other Laserjet 4350 drivers (4350, 4350n, 4350tn, 4350dtn and the 4350dtnsl) but the download files are identical, even though HP make you go through the rigmarole of 'selecting' your correct model. I'll make enquiries as to whether any other HP model drivers would be compatible, but, this being HP, I don't hold out much hope.

Thank you for your suggestion, though, and I envy you your trouble-free printers!
