Print speed and durability matter differently here than on a receipt printer. A label printer used for daily pricing runs needs to keep pace with batch printing, often dozens or hundreds of labels at once ahead of a restock or price change, rather than the one receipt at a time pattern a checkout counter produces. A printer sized for occasional use will slow down noticeably under that kind of batch load.
A label printer does a very different job from a receipt printer, even though both use thermal technology. A receipt printer prints one long strip per transaction. A label printer prints individual labels, often for pricing, product identification, or shipping, and it needs to handle a completely different volume pattern across a working day.
A kitchen display system, usually shortened to KDS, replaces the paper ticket rail that has run restaurant kitchens for decades. Instead of a cook grabbing and marking up a paper slip, orders appear on a screen mounted in the kitchen the moment they are placed at the counter or table, and the cook marks each item complete on the screen instead of crossing it out by hand.
Cost comparison is not as simple as it looks on paper either. A basic cash register costs less upfront, but a business that outgrows it ends up paying twice, once for the register and again for the POS system it should have started with. A POS terminal built for the transaction volume a business actually expects avoids that repeat cost.
For most retail and food service businesses handling more than a small handful of product lines, the reporting and inventory tracking a POS system provides outweighs the simplicity of a traditional register.

Kitchens that benefit most tend to be the ones running multiple order sources at once, such as a counter, a drive through, and online orders all landing in the same kitchen. Keeping all three organized on paper gets messy fast, while a screen based system keeps every order visible in one place regardless of where it came from.
