Windows 10: USB POS Printer Sudden Disconnections

If you are facing issues with your USB Point-of-Sale (POS) printer suddenly disconnecting while using it with a Windows 10 PC, you are not alone. This article provides a detailed explanation of the possible reasons behind this problem and offers solutions to resolve it.

Context

A USB POS printer usually connects to a Windows 10 PC through a USB cable, and the printer's driver allows the PC to access and send print jobs to the printer. However, in some cases, the printer suddenly becomes unavailable due to various reasons.

Possible Reasons for the Disconnections

Some possible reasons for the sudden disconnections of USB POS printers from Windows 10 PCs include:

Outdated or incorrect printer drivers
Power management issues causing the USB port to shut off
Hardware or cable issues
Interference from other USB devices

Solutions

Solution 1: Update the Printer Drivers

Outdated or incorrect printer drivers might cause sudden disconnections. Follow these steps to update the printer drivers:

Press Windows + X and select Device Manager.
Expand the Print Queues category.
Right-click on your POS printer and select Update Driver.
Select Search automatically for updated driver software and wait for Windows to finish updating the driver.

Solution 2: Change Power Management Settings

The USB ports might shut off due to Windows' default power management settings. Follow these steps to change the settings:

Press Windows + X and select Device Manager.
Expand the Universal Serial Bus controllers category.
Right-click on each USB Root Hub and select Properties.
On the Power Management tab, uncheck Allow the computer to turn off this device to save power and click OK.

Solution 3: Check Hardware and Cables

Damaged cables or bad connections can cause sudden disconnections. Inspect the cables, USB ports, and the printer's USB interface for any visible issues, and if needed, replace any damaged parts.

Solution 4: Disconnect or Change the USB Devices

Interference from other USB devices might cause the disconnections. Disconnect other USB devices and check if the printer still disconnects. If so, consider changing the printer's USB port or using an external USB hub.
