Do you intend to use different sizes and types of paper?

A lot of printers have trouble with handling paper with a highly textured surface, pre-printed stationery, linen faced paper and some coated papers. Consider the paper handling specifications of the printer to see if it will be able to process the sizes, weights and types of paper and other media you generally use. Consider extra trays for letterhead, cheques, coloured paper, A5, or plain A4.
