Imagine that we buy a monitor and its input does not match our video card, even though it has the same type.
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.
Their prices are becoming more affordable and operating costs lower.
Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc. But still, such home printers are far behind the professional equipment used in professional printers.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. .
