I have a Hewlett Packard Photosmart (model number unknown) which prints, photocopies and scans. I think it's wireless too. I mean we can print to it from laptops anywhere in the house. Very handy. Works well.
Something I check is the cost of new ink cartridges when deciding on a printer. I had one previously which would take the cheaper ink cartridges but it did not show the level of ink remaining which was a real pain as we often ran out mid print job. If I remember correctly, like Anne, if one colour ink was low it just wouldn't print at all. I hated that printer with a passion.
I also like the various options like 'economical' which I think must use less ink.
My cartridges cost around AUD $16 each and I buy the HP ones. My children both need decent quality prints for their graphics based studies and I find the ink pretty reliable. Cartridges don't last long but we are pretty heavy on ink usage.
