Gee POSPerson I guess the device that View shows was built and sold just for “ships” and giggles.
Since you call yourself POSPerson it'd be nice to also understand how kitchens actually work and certainly as the kitchen staff are working on prep, earlier orders and clean up the sound of the printer tells them there is a new order and that is helpful.
I've been in thousands of kitchens and that is actually how it works. I’m not saying that the sound is "critical" just that all things being equal it’s a benefit, and that is the fact.
By the way for about ten years now it's been a sign of a complete and utter dufus* to have an AOL e-mail address, in my opinion. Perhaps you could try and not look like you're stuck in 1988.
Home users are not quite as pathetic, but someone who wants to portray themselves as a "tech person" really needs to have a clue, but on the other hand actually asking if the sound of an impact printer has any effect in a kitchen kind of rules you out as someone aware of the restaurant business in the first place so I suppose it doesn't matter.
Of course one would have to talk to a chef (or a thousand) to have a clue about what actually goes on in a restaurant. I have thought for years that learning the POS business takes time, but you need an understanding of the restaurant business first to best serve the industry.
