How to resume printing receipts and labels if the printer has stopped printing: the USB or IP port has changed

 The video covers typical situations: after a Windows update, a USB port change, or an IP address change, the printer stops printing and the program no longer detects the device.

It explains how to check whether the printer is working properly using a self-test, identify the correct USB port in the system, and reinstall the driver. It also shows how to disable delayed printing and USB power saving, which often cause loss of connection with the equipment.

It also covers how network printers work: how to bind an IP address using a MAC address, configure a stable TCP/IP port, and avoid problems related to WSD.
