Printer as hosting for a light site?

Question

FTP

Good day. There is a printer that has a static IP on our local network. He has pretty good hardware for the tasks I need. And the task is very simple: upload a one-page via FTP (ordering meals for employees) that can be opened by anyone from the local network at xx.xx.xx.xx/eatme.html.
What we have:
An HP LaserJet Pro network printer with FTP support and, apparently, Telnet.
The printer's admin panel, which obviously runs on the printer's embedded web server.
The absence of an extra server and IP addresses, and it’s not worth buying a new one if there are a dozen printers that occupy addresses that, well, need to be used for other needs of simple information pages that are unlikely to create a load on the printer.
What we don't have:
The login and password on FTP, since the manufacturer did not indicate this at all, was found empirically.
Descriptions of the system on which the printer works, which is most likely a stripped-down Linux, is understandable.
The question is how to get the password, well, or perhaps one of you has come across similar things and will suggest a solution. Thank you.

Answer 1

If you already have a server inside the network, then why don't you put the page for ordering lunches in a separate subdirectory on the server: companyname.local/eatme/
This will also not take an "extra" ip in your internal network, and your employees will not have to remember xx.xx.xx.xx (and if you are going to convert several printers into a web server, you will have to raise your local dns as well).
