We had a roland without one when i started working here, when we started looking at 2nd printers i INSISTED on one with. we run with our take up on 90% of our jobs, i hated babysitting the roland and god help us if a customer came in mid print i had to talk to... nothing is more frustrating/ unprofessional then having to excuse yourself for a second to go check on your printer because everyone else is also busy.
I think for the added cost it has paid for itself many times over already.
