"Printing anything larger than A4 can cost a lot of money. Large format
printers start at around £1,000 and rise steeply from there. There is an
intermediary path though. If but don't need A2 or bigger and only want to go
up to A3+ - A3 prints with full bleed then Epson's Stylus Photo R2400 is a
versatile medium format machine. It can handle sheet, roll and thick media
of up to 1.3mm, which makes it suitable for small signage."
