Uncle Henry’s, the iconic magazine of Maine classified ads, may stop print publication after this week because its printer is closing.

The customer service department of the weekly magazine, which is based in Augusta, said in an email Monday that its printer has decided to close this month and that the staff are in the midst of trying to figure out a replacement printer.

“Our hope is that we can connect with a new printer and continue to print Uncle Henry’s, although it may be in a slightly different format to accommodate what the printer can produce,” the email said.

The magazine said it has one more book coming out this week in print and will continue to run its online site while searching for a new printer.

In business since 1970, Uncle Henry’s includes two print publications, a classified website and numerous mobile apps. It describes itself on its website as “THE destination for buying, selling and swapping just about anything.”

The magazine also posted Monday on Facebook that it may be ceasing print publication. More than a dozen people commented on the post within a half-hour of the post being made.

“You guys have been a Maine staple,” one person wrote. “A time-tested, long-lasting, hellofa, awesome run. Many people’s lives you have been a part of here in Maine. Thank you for all your hard work, perseverance, and support from the north to south of Maine.”

“Thank you for continuing this great tradition!” wrote another. “I have some family members that call it the Bible.”

A person who answered the phone at Trumbull Printing in Trumbull, Connecticut, on Monday evening said that the company prints Uncle Henry’s and confirmed it is closing but said that for any further information, a reporter would have to call back Tuesday.

The company’s vice president and general manager did not respond Monday night to an email seeking more information, including the reason for the closure and whether any other Maine publications would be impacted.

The decline of the printing industry, including magazines and classifieds like Uncle Henry’s, as well as news media, has been well documented across the United States. Many newspapers no longer offer a print edition seven days per week, as they’ve shifted their emphasis to digital publication. And print advertising is also in decline.

Uncle Henry’s did not respond to an email Monday night seeking additional details on its search for a printer, and no one answered the phone number listed on its Facebook page.

The popular magazine was also the subject of a reality TV series, “Down East Dickering,” that launched in 2014 on the History network and ran for two seasons. The show followed the exploits of penny-pinching readers as they scoured the guide and then dickered with other frugal New Englanders for a tractor part, a hunk of scrap metal, a cow or a bicycle.
