We need a new printer

Claire
I need to print in colour, but I don’t mind if it is not fast. What kind of printer should I buy?

-I think you should buy an inkjet printer, because this is cheaper than a laser printer and it can print in colour.

Marshall
I need to print really fast. I’m not going to use colour or images. Shall I buy an inkjet printer?

-I think you shouldn't buy an inkjet printer, because the laser printer is the fastest and it is cheaper than a mono laser printer.
