A lot of internet-connected receipt printers print spam, namely the Antiwork manifesto, encouraging people to talk to colleagues about their salaries and putting pressure on employers.
The Vice Motherboard talks about printing of strange checks. In recent days, complaints about hacking of receipt printers have been actively received via Reddit and social networks (1, 2, 3, 4, 5).
There are many similar posts on the r / Antiwork subreddit, some of which contain the same manifest. Other posts focus on worker empowerment, but they all invite the post’s reader to go to the subreddit and jump into action.

Some have even suggested that spam on receipt printers is just a fake, designed to give the impression that the r / Antiwork subreddit is responsible for something illegal. However, Andrew Morris, founder of information security firm GreyNoise, told reporters that his specialists are observing how real network traffic goes to unsecured receipt printers around the world. It looks like several people are sending such messages to print all over the Internet indiscriminately.
