I (somehow) have been saddled with researching the next printer for one of our offices. Currently they've got an HP Deskjet F380 - it seems like a nice machine, with a scanner and photocopier, but I suspect it's designed for home use rather than office use; it uses cartridges at a horrific rate. Can anyone recommend any alternatives? I need one which still has a photocopying function - paying more isn't an issue, as long as it's economical with ink and can cope with high volume usage. Chars.
