Make it a permission rather than a rule. In MISAll, price overrides, discounts, voids and refunds are per-user rights, and a cashier can be given a maximum round-down amount so small change is handled without opening the door to arbitrary edits.
Telling staff not to discount does not survive a busy Saturday. The useful control is that the button either does nothing for that account or is capped at an amount you chose.
The round-down cap is the setting most owners want and do not know to ask for. Cashiers legitimately need to knock a few cents off to avoid handling coins nobody carries. Set a ceiling on that and the behaviour stays convenient without becoming a hole.
Permissions only tell you what someone is allowed to do. To see what actually happened you want the other half: sales by cashier, and the system log of who edited which document and when. Owners who catch problems usually catch them in the log, not in the permission screen.
This sits in the POS. Licensing is covered on pricing, and the rest of the questions are in Answers.

Yes. In MISAll the interface language is a property of the user account, not of the installation, so the back-office machine can run in Chinese while the front counter runs in English, Spanish, Arabic, Khmer or Indonesian at the same time.
Because the printer is being asked to render characters that are not in its built-in font table. The fix is to stop sending text and send the receipt as a rendered image instead — MISAll can print in graphic mode, which is why non-Latin scripts come out readable.
MISAll switches to offline mode automatically and keeps taking sales; the transactions sync once the connection returns. You do not have to notice the outage or press anything.
