The Epson T1631 Black XL ink cartridge is most at home in a high volume office environment when high quality text documents are needed regularly. This cartridge fits a number of Epson’s Workforce printers, most of which are multifunction options that can print, scan and copy. This XL version is the same size as the T1621 Black but it contains more than double the amount of ink which means it can print far more before it runs dry and requires replacement. If you print less frequently the standard sized cartridge may well be the better option but most people will save money in the long run by choosing the XL.
