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. By using the parallel interface for the receipt printer you then open up the serial and USB ports for other devices. According to one study, the printer ink cartridge business is responsible for $21 billion (US) per year in sales.
In most cases, they send the printer off for repair and never get beyond the simple repairs that can be done locally. Which is similar to HP printers for sale most of the time. Concerned about the burgeoning cost of printers ink, the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have established testing standards for printers. Parallel printer connections are newer technology than serial interfaces.
Even in the best of situations you should expect to have hours of downtime if a replacement printer is needed. This means that anyone who refills a Lexmark cartridge for reuse could face charges and legal action. Parallel printer signals are not good for long distances.
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. Tonik also offers an unconditional guarantee on its Tonik brand of compatible ink cartridges, as well as selling original manufacturer product for all leading ink and toner printers at low prices. Usually this is the exact opposite of Canon printers for sale. This helps greatly with receipt printers as it keeps the printer cable securely in place and difficult to accidentally come loose.
Downtime is reduced from hours or days to a matter of minutes. Not all point of sale software uses parallel printers. Your customers are not inconvenienced by not receiving a receipt, guest check or by having their food come out of the kitchen slow because the kitchen printer is down.
