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.
Just using them is not a problem for them, because home printers are designed in such a way that they are fully intuitive and work perfectly with computers and laptops.
They are ordered wholesale and also consumed in bulk.For each order, the production costs are optimized, and the appropriate technique and type of printing is selected. Graphic designers, DTP operators and printers deal with this. They are responsible for the quality of the printout and as soon as something is wrong they are the first to be targeted by the dissatisfied boss.
Their work is quite hard and I have to admit that you have to really have a fuss to do it.
