If you cannot print first check to see if the printer that you are printing has a ready light.
The ready light should be a steady green light not blinking green. If it is blinking or not on then try turning the power off then on again.
If printer is ready
Go to your Computer Screen then click Start (bottom left corner of the widows screen) or type printer for windows 10
Click “settings” “printer and fax” or click printer and fax if you see it. Select your printer for windows 10
Now you are in the printer control panel. Check the printer name that you are printing to see if it has your print job. Usually it shows the number and name of jobs in the printer.
Double click on the printer and delete all the print job below the first one on top.
Leave the top job (job number 1) last.
If you are using the usb cable to connect to the printer them unplug it from the back of the printer then plug it back in.
Try to print again.
If you are using the network printer you need to turn off the printer and wait 20 second and turn on again.
If you have a print server (box that printer connected too) turn off, wait 20 seconds, then turn on again.
If all attempts failed please submit a trouble ticket here.
