This is because such sets include not only the printers themselves, but also photocopying paper and additional printing accessories that can be used in everyday work while making prints.
Therefore, both small printers with an additional scanner and large scanning devices go on sale.They work perfectly in offices, schools, in the back of the shop or at universities. Therefore, it is not uncommon to sell printers with a scanner, and then you can order almost any number of such devices and they will be delivered almost instantly to the delivery address.
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.
