HP currently make over 50 different printer types for the UK market, ranging from the basic printers, going on up to printer scanner copiers and upto some really detailed higher priced printer both for home and business use.

It is well known that HP probably make the most ink efficent home printers at this moment in time.

HP made it easy for people to find the ink they need for their printers, they simply put numbers on them all.

Usually numbering from 1 to 999, it is the simplest of all the manufacturers to find the ink that you need. On the ink cartridge that comes with your printer should be a number, that's the one you need to buy when replacing it.

 A few years ago you needed to take your printer make / model and sometimes serial number to replace the ink.
