We've got a Dell something or other at home. Which isn't the same since Southampton left there. The manufacturers say you have to get ink cartridges through them only. Except that they don't sell them.
At work, we've got a Xerox Docutech X12. It looks like a photocopier (well, it is one), and prints up to 1200dpi on SRA3 400gsm paper. Quality. And all the consumables (colour toner, cleaner etc) are free.
