Cause 1:  The print queue has multiple print jobs stuck in it and must be cleared out.

Remedy 1A:  Open your Windows Control Panel and go to Devices and Printers.

For Windows 7:  Click Start, Control Panel, Devices and Printers

For Windows 8/10:  Click the start button and just start typing Control Panel. The search will return the result. Select Control Panel and then go to Devices and Printers. (If you just see categories, change the view in the upper right to small icons.)

Right click the printer you are attempting to send reports to and select "See what's printing'.  

This will bring up a window with your current print jobs in the print queue.  If you see multiple entries, left click them once to select and then right click and select Cancel.  If this does not clear the print queue, follow Remedy 1B.

Remedy 1B:  Close Kennel Connection and all other programs, unplug the printer USB cable and then restart the computer.  Once the computer is restarted, plug the USB plugs back in and Windows should re-detect the printer.  Open KC and try printing again.

Please note:  If you use multiple computers and this is your server/main computer where the database is, you will need to close KC on all computers prior to restarting the server.

Remedy 2:  Click the Ctrl, Alt, Del buttons on your keyboard to open the Task Manager.  Or, right click on the Start button and click on Task Manager.

Click on the Services tab.

Click on Open Services.

Scroll down to Print Spooler.  Right click on it and select Restart from the menu.  Once the service shows in a Running state once more, try printing again.
