They break down less frequently, so they require fewer maintenance calls. Ink ribbons are much less expensive than toner cartridges. I have no way to confirm this, but if it’s true, DAMN! Costĭot matrix printers are cheaper to operate than laser printers. I even read that in outstations, the data is relayed from the airline to the gate via a 9600 baud phone modem because there are no cable or satellite connections to get information there any other way. These programs are written in computer languages that haven’t been used for decades, back when no one had even heard of a laser printer, USB, WiFi or “the cloud.” To make these legacy systems talk to laser printers would be amazingly challenging and labor-intensive.
The reservation systems and other systems that run the airport are controlled by programs written for mainframe computers. Here are some of the most common explanations: Technology I’ve found many instances of people asking this question online, but there doesn’t seem to be a single definitive answer.
This technology is decades old, so why do they still use it at the airport?
Well, unless the paper is misaligned and the sprockets miss the holes, but let us try to forget that if we can. Using a series of “pins” and an ink ribbon, you slowly but surely get your printed document. The printing is done by a head that moves across the page from one side to the other. After you’re done printing, you tear off these edges, leaving you with something looking like this. Paper is fed by a tractor system, meaning the pages’ sides have perforated edges that align with spokes that keep the paper moving. Way back before we all had laser printers, the majority of work was done with these ancient machines. I know there might be some of you reading this who have never seen one of these before. If you’ve ever been sitting or standing near an airport gate before a flight, there’s a good chance that you’ve heard a printer that’s spewing out seemingly infinite amounts of paper.
