Any laser printer that doesn't support a sensible set of printing protocols (postscript, for example) does not belong in an office. It's fairly hard to find one, but if you're looking for something that will be absolutely no use to anyone, look no further than the Epson Acculaser C900 [epson.co.uk]. One of our clients bought one of these for their accounts office, where they have a high printload. Once they realise how much it would cost them, they sent it into the MD's office (which does very little) and replaced it with one of these [hp.com]. Since then, the Epson has broken down twice.

Kindly recommend to your boss that any money saved by buying cheap GDI printers is lost very quickly in maintenance and consumables.
