You can configure your STM device with ethernet.

Then, you can periodically make connections to your known IP for your printer.

You can use TCP requests as a CLIENT to your printer which is SERVER.

Data he returns you back (print counter and so on) you parse easily and display on LCD.

This library should help you a lot for ethernet using TCP client:

You can check the page html source code when you access printer with browser.

The page contain a request for printer data (counter...).

Form the STM device you must send this http request (post or get to the printer) and decode the printer reply

With firefox browser the traffic request/reply can be easily view with firebug addon

But also wireshark can be used for traffic analysis
