HI
there can be several reasons in my opinion:
Configuration problems: Check the POS configuration settings and make sure they are set correctly. Make sure that the tax printer is configured correctly and that the correct settings are in place.
Network problems: Ensure that the network connection is stable and that there are no problems that could cause the system to lose connection to the tax printer or database.
Software Bugs: It is possible that the problems you are experiencing are caused by software bugs. Check whether updates or patches are available for the POS system in use.
Product names: If product and ingredient names are long, the fiscal printer may have problems printing receipts. Try shortening the names to see if the problem is resolved.
Hardware problems: You may have hardware problems with your fiscal printer or other POS equipment. Check that all equipment is working properly.
User error: It is possible that a user error is causing the problems. Check that all employees have been instructed in the correct use of the POS system.
