If you don't have a manual, download one from
https://archive.org/details/printermanual-hp-laserjet-2100-service-manual
and read chapters 3 (printer) and 6 (comms troubleshooting).
The other page that's useful is
http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-bpj05678
Before you reset anything, get it to print the current configuration
that your colleagues may be relying on. Make sure you've got the page-
count: were you to hold the Job Cancel button *too* long when you do
your factory reset, you would clear this number. There's also a
separate network configuration page.
The reason I mentioned printing is that the web page above mentions
holding a button (Test in this instance) for anything up to 30
seconds. On your printer, that *would* clear your page count.
Then do your reset and see whether, when you switch it on and connect
it to the router, it automatically finds out what network it's on and
what it's address is. Assuming the network card has reset, it *could*
come up as 192.0.0.192 (but it shouldn't: DHCP should work).
Cheers,
David.
