Cost per printed page

[AnotherDayInParadiseLost]

How do you charge for printing stuff on your printer? I've been freelancing for about a year but I've just had to print out my first substantial quantity (250 pages).

Any idea?

Would depend massively on the type of printer and the ink coverage if an inkjet.

It costs me about 3.5p for an A3 full colour print + paper.

Thought I might have to do a Boring Sum ...
