Odoo 11 PoS Arabic printing posboxless and user restriction per pos

Greetings I have installed odoo 11 with enterprise theme with Pos module for resturant on my server I face the problem that I can't print arabic through bosbox and as well can't access directly ip printers what I need is the following - Arabic Receipt printing - posboxless printing directly to ip printers with cashdrawer control - as well to be able to print kitchen orders through ip printer once the order is placed - Restrict access to each PoS to specific users anotherthing away from PoS module - to get stock increased once invoice is posted without extra mocements you may communicate for further details I prefer if you have your own server to test before installing on my server thanks
