With an A3 printer, you can also print larger documents. An A3 print is 2 times the size of an A4 print. Flyers, posters, brochures, and other prints, for example. Want to scan and copy as well? Choose an all-in-one A3 printer. With some printers, you can also print in A3+ size. This leaves space for cutting marks for prints. You can choose from HP A3 printers, Epson A3 printers, Brother A3 printers, and Canon A3 printers.
