Reasons Behind mPOP Printer Not Detected or Cash Drawer Not Detected

The solution to Fix QuickBooks mPOP Printer Not Detected / Cash Drawer Not Detected Issue

However, there are multiple ways to get rid of such printing issues. Below are a few reliable solution steps that may help you overcome this issue with ease.

Let’s execute one by one:

Solution 1: Purge the printer’s memory 

  • Start with turning off the printer 
  • Turn the printer back on while pressing and holding the feed button 
  • Release the feed button when the printer starts its self-test 
  • Once the test is finished, try printing from within Point of Sale once more.

Solution 2: Make sure the printer is powered up.

Check to see if the printer’s power cord is attached and if there is a power light on when it is turned on. Connecting the receipt printer to a USB hub will not provide enough power for the printer to function properly.

Solution 3: Confirm if the printer is on or off.

  • Choose the Control Panel from the Windows Logo button
  • Then double-click the receipt printer under Devices & Printers 
  • Choose Printer >>> Cancel All Documents after selecting X documents from the queue 
  • Confirm the action by clicking the “Yes” button
  • If Pause Printing is checked, click Pause Printing on the Printer menu once more 
  • Close this window and run a test on the cash drawer. Proceed to the next solution if it fails.

Solution 4: Bypass the spooling process for printing

  • Right-click the receipt printer in the Devices and Printers box 
  • Then select Printer Properties from the Control Panel 
  • Next, go to the Advanced tab and then Print to the printer directly 
  • Test the cash drawer function by clicking OK. Continue to the next step if it fails.

Solution 5: Remove the printer and reinstall it.

  • Right-click the receipt printer in the Devices & Printers box, then select Remove device  
  • To confirm the action, click “Yes”
  • Repeat this procedure for any additional printer copies that may be installed  
  • The receipt printer will be reinstalled
  • The cash drawer should now function properly.
