These printers also have an expansion network card.

A decade ago I worked on a project to deploy a couple hundred of these to a restaurant chain as part of a POC for an online ordering program for pickup orders. The requirement for each franchisee was to acquire a static IP and configure one of these printers to bind that static address using a network card that replaced the serial connection. The online interface from the vendor was configured with that static address and sent text over TCP to print the incoming orders. The printer than just printed whatever it received.

The project was initially deployed without any whitelisting or authentication (at the vendors behest) so for a couple months these printers were printing a mixture of garbage and scan attempts from random devices connecting. It was quite humorous at the time but scares the hell out of me given the other things that were on that internal network. The project failed for other reasons, but it looks like that particular vendor is still around.

They are quite fast (200mm/s). If you send a malicious job you have 12m of paper sticking out of the printer within a minute :D

Fujitsu fp-2200 can print 400mm/s, it's quite mind boggling how fast the paper comes out :)

Also if you hold feed while power on you get a interactive menu, printed on paper. Probably works on Epson printers also
