Hello,

I am facing one issue. I have an android POS with an inbuild USB Printer and Cash Drawer RJ 11 Port. I want to open the cash drawer without using any printer utilities. Is there any solution for that.

this is beyond software. to open the drawer you need a 12V pulse , usually phones etc support use 5v
