You would never want your point of sale system to be down because you ran out of paper. Receipt and remote printers are the parts of your point of sale system most prone to failure. We are not suggesting that you have a warehouse full of backup printers, but we are suggesting that you can almost eliminate your downtime by having a single backup printer for your business. This is also true for printers for sale. Using the standard parallel printer connection for your receipt printer gives you the option to utilize the serial and USB connections for other peripheral devices that will not work on a parallel interface. Before you buy that bargain basement brand-name printer, be sure to look into the cost of ink cartridges.

In more and more situations, this means that the dealer that you bought the equipment from is not the person who is repairing the broken hardware. Which is similar to HP printers for sale most of the time. In Japan, Epson won a case with the result that the sale of re-manufactured cartridges is banned. Parallel printer connections are newer technology than serial interfaces.

For this reason, if you only bought a single backup printer for a point of sale system that had both thermal and dot matrix printers it would probably be a dot matrix printer. Those who fail to return them are breaking the law and could face legal action if they refill a cartridge, send it to a third-party refiller or simply do not return it to Lexmark. Another reason that parallel cables are not good for long runs is the thickness of the cable and the cost.

You keep other supplies in your operation and you should consider keeping a backup printer as well. Those buying printer ink cartridges in the UK and elsewhere are advised to investigate the policies surrounding the reuse or refill of these indispensable items before engaging in this practice. Usually this is the exact opposite of Canon printers for sale. These same connectors are perfect for receipt printers because they lock into place.

Note that I said most, as there are some printers that do have multiple interfaces. Not all point of sale software uses parallel printers. You are not as stressed by having your point of sale system be crippled by a down printer.
