My problem is that I need to print envelopes suitable for A4 content format. This is C4 envelope (229 x 324). I can see two ways of solving this problem: 1) printing on labels; 2) a printer for A4 extra paper size (235 x 322). When I addressed myself to computer shops, they just don't know how to solve any of these problems. They say that in order to buy a printer for labels, I'll have to go to a shop for in-store equipment. And they also say that their printers can't print A4 extra. But as a matter of fact, our suppliers have already solved this problem. Why can't I? Could you recommend me some models of printers?
