Oddo 14, custom_receipts_for_pos, screen OK but print?!

[marcogaio]

I'm using your module to deploy a little PoS for a winter/Christmas kiosk, for beneficial purpose: il chiosco dei Babbi Natale (the Santa's Kiosk).

I need to modify the PoS recipe, and found your marvelous module: with my little HTML and CSS knowledge i've done what i need. But modify recipe work in preview, NOT in printing. I've tried to read docs and (i know little or no python) the code, but i've not found a way to enable print, or something like that.

I'm using for printing old POSBox (PyWebDriver, indeed) but i've tried also IoTBox and the result is the same.

What i'm missing? Thanks.
