A lot of consumers own printers, and not many know the specifications of their printers. Specifically, the inkk cartridges their printer takes. The easiest way of finding out which cartridge is right is to check the ones already in the printer. However, most consumers don't do this before blindly entering a store to buy new ones.
A simple website where a user can enter the make and model of their printer, returning the cartridge(s) that their printer takes. This saves them a few minutes of Googling, sure, but the real use is for retail employees. With the website saved to store-owned PDTs, workers can find the cartridges for customers with ease.
