Can't print the Schlock hotel key card.

Schlock hotel key card can't print brakes,

This problem may be due to whether your credit card device is a bit ineffective and how long it has been used. If it is a long time, it is likely that the credit card module is not sensitive.

You can check and rule out first. If it still doesn't work, try to reconfigure the business card printing program. Maybe it's a packet loss or something.
