Question: I am wondering what type of printer I could use to print 36 inch to 42 inches in width posters, banners, or outdoor signs and the like?

There are many companies that produce large format printers, but I can’t really tell you which ones are going to fit your needs as I don’t know what your end game is, and we also aren’t allowed to promote brand names of printers, other than to say, do your homework and try to find companies using the machine you’re interested in and interview them if at all possible.
