I'm using Odoo 11 CE with Jposbox on Windows. I already activated the 'cashdrawer' & cash control in POS module. the cashdrawer would open if i print bill & receipt.

Problem:

1. I need to count money for opening & closing, how to open cashbox from the system? without printing

2. The 'open cashbox' button on payment screen also doesn't work

Anyone can solve this?
