Hi!

I'm still new to odoo. Just got my odoo 14 CE set up and going. 

One thing I'm struggling with is receipt size on my POS...

I have 57mm thermal printer and anything I print right side is cut off...

Seems like default size is 80mm?

I know I have to edit css and xml files but I don't know where the files are exactly located or what to change...

I googled a lot but most of the versions were older and file/folder names were not same anymore... :(

Can anybody please help me in detail so very noob like me can understand?

Thank you so much in advance!
