In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.
The first commercial printers generally used mechanisms from electric typewriters and Teletype machines.
In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output.The plotter was used for those requiring high quality line art like blueprints.Źródło: https://en.wikipedia.org/wiki/Printer_(computing)
Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers.
Printed roll, solvent, water, anhydrous - long to exchange.The quality of such printouts is higher, which entails the obvious higher costs of printing itself.
Of course, large outlays are still cheaper, but this difference is not as big as a few years ago. The potential market for low-cost prints is small, local companies producing small quantities of goods.Recently also a lot of home brewers begin to label their own beers, of course not for trade, but for example for contests.
