A black and white laser printer, an HP LaserJet 4250tn printer from around 2006.
The printer has two paper trays each holding 500 A4 sheets and is reasonably fast printing over 40 pages a minute when producing multiple copies of the same page.
Has a network port, USB type B port and centronics port.
The printer had sat unused for a few years but I have given it a clean and printed some test pages although the print path could do with some further cleaning. One picture shows large text that has been printed to demonstrate that cleaning is needed.

Dimensions: 40cm (width), 44cm (depth), 48cm (height)
It weighs about 30kg.
