Printing on a Paper Roll with the Pagewide P57750dw

[Markus36]

I would like to print on a continuous paper roll with the HP Pagewide P57750dw

This was possible on other printers just by choosing "continuous roll" in the paper format selection, here it doesn't appear. And when I try to create a custom page format it only accepts 55 cm max, or almost 22 inches, but no infinite roll option.
Maybe this could work with some custom firmware??

P57750dw doesn't support printing on a roll, sheets only.

I want to do something similar to this:

Here they modified the Hp OfficeJet X551 to print paper rolls, even though it also doesn't inherently support paper rolls.
