Yes—ask general print shops rather than photo labs. What you want is a poster printed on standard matte paper (around 100–130gsm was mentioned), using large-format inkjet or color laser printing, not a photographic print process.

From the answers, Staples was one option for inexpensive poster-size printing, with color laser up to A3 and inkjet plotters up to A1, and a choice of papers. Quality was described as acceptable rather than exceptional.

A key limitation is that traditional litho poster printing is usually economical only for large runs, so it’s hard to find true mass-market-style posters as one-offs. For short runs, modern digital print shops are the better route.

If you want better results than office-store printing, contact local commercial printers and ask specifically for:

• short-run digital poster printing
• matte poster paper (not photo paper)
• rolled output

Another practical approach is to look at posters you like in public spaces and check whether the printer is credited, or ask the advertiser/promoter who printed them.
