Physical Checks
Ensure that both ends of the USB cable are firmly inserted. If the printer is networked then make sure the Ethernet cable is firmly inserted.
Try the end of the cable in multiple ports on your PC/laptop if available.
If you own another USB A-B cable then try this cable in conjunction with your printer and computer.
Set the Printer to “Online” Manually
Go to the Start icon on the bottom left of your screen then choose Control Panel and then Devices and Printers.
Right-click the printer in question and select “See what’s printing”.
From the window that pops up choose Printer from the bar at the top.
Select “Use Printer Online” from the drop-down menu.
Remove All Pending Print Jobs
From the “See what’s printing” menu mentioned previously right click and “Cancel” any print jobs present.
With the print jobs removed select “Use Printer Online” again.
If any suborn print jobs remain then try restarting both your PC and printer.
Removing and Reinstalling Your Printer
Right-click the printer from Devices and Printers and select “Remove device”.
Now add the printer again by selecting the Add a Printer option from Devices and Printers.
Removing Drivers and Packages
Make sure you are using windows as an Admin or sign-in as one.
Go to Start>All Programs>Accessories>Command Prompt.
With command prompt open type “printui /s /t2” including the spaces to open the Print Server Properties window.
Now remove the Driver and Package for the printer in question.
You can now add your printer again by selecting Add a Printer from Devices and Printers.
Your printer should now be showing as online and allow you to continue printing. If not there is likely to be an issue with the printer electronically and I would advise contacting the printers manufacturer or a printer technician.
