Printers come in all sizes. Printers do different kinds of printing. Most are general, commercial printers, rather than specialty shops. Lots of consumers assume that all printers do the same thing. It's not that simple.
Different presses mean different capabilities and different run lengths.
Printing prices vary from shop to shop. Always ask for prices before you hand over your job to a printer. Select your paper carefully with the printer's help. In fact, if you're quoted a price that is too high for your budget, ask your printer to suggest some alternatives. Determine your quantities wisely.
