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. The same is true with regard to not have a supply of ribbons to use when your existing ribbon gets too light to read. This is also true for printers for sale. For the most part, scanners, cash drawers and pole displays will not work with a parallel interface. Follow the money.
What this means for you is less cost of repairs but a longer down time. Which is similar to best laser printers for sale most of the time. Virtually every major printer manufacturer has been involved in lawsuits regarding the sale and use of re-manufactured inkjet or laser printer ink cartridges. A parallel connection is a wide 25-pin female connector.
Even in the best of situations you should expect to have hours of downtime if a replacement printer is needed. In 2005, Lexmark won a suit that gives the company the authority under patent and contract law to enforce the “single use only” policy that’s written on the boxes in which their cartridges are packaged. That makes them difficult to use as remote printers since those runs require distances of 100′ – 300′ feet from the connection point.
Even if you have a mixture of thermal printers and dot matrix printers in your point of sale system, you should consider having a simple dot matrix printer as a backup. 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 cheap printers for sale. USB cables do not lock into place and can come loose with repeated movement of the printer.
Note that I said most, as there are some printers that do have multiple interfaces. Be sure to consult your owner’s manual or your software provider for more details. Don’t be caught without a backup printer for your operation.
