Aren't most network printers connected to office networks with public internet access? I sounds like this printer was making outgoing connections, and I doubt many people/companies go through the trouble of specially blocking those from printers.
You'd have to be especially security conscious and paranoid (especially 20 years ago!), to be operating under the assumption that your own equipment is working against you.
- lostlogin 5y agoIt doesn’t take long as a system administrator to become certain that printers are working against you. By and large they have user hostile hardware and software.

- christkv 5y agoI’ve found this is true for everything but brother printers. I’ll never buy another brand again.
- jaywalk 5y agoThe Brother color laser printer I purchased 7-8 years ago was the best printer purchase I ever made. I barely print, and the toner doesn't dry up the way inkjet ink does. It just sits there, ready for the occasional print job. No BS software required.
- lostlogin 5y agoThank you and the parent. I’ll try this path in the future.
- throwawayboise 5y ago20 years ago I would have expected that most printers were connected to a parallel or serial port on a PC and any network printing functions would be handled by the PC. But then I think, wait, that was the year 2002 (which seems like yesterday when I say it) so maybe printers with direct network connections were pretty common then. My sense of the passage of time has really gotten compressed as I get older.
