I am having the EXACT same problem....anyone with some ideas?

Hi ramarelo,

If the ‘Internal error - incomplete session by timeout’ message appears, there may be an issue with your printer drivers. Please follow the instructions below to correct it:

(1) Reinstall the printer driver first.

(2) If the problem persists, Remove the drivers completely and then download the latest driver. Please use the link below to download drivers:

I hope you find this helpful.

Hi, I have done exactly what you suggested (removing the driver and reinstalling) and still having the same issue.

Hi, I also took the same method apply what you recommended But my problem is still now, So kindly resolve this issue anyone.

Thanks

Troubleshooting offline printer problems in Windows

Check to make sure the printer is turned on and connected to the same Wi-Fi network as your device. 
Unplug and restart your printer. 
Set your printer as the default printer. 
Clear the print queue. 
Reset the service that manages the printing queue.

Hello everyone.
I have almost the same problem.
PWG ERROR: Incomplete session by time out
POSITION : 0x3elc (15900)
SYSTEM : h6fw/os_hook
LINE: 1430
VERSION: SPL 5.58.01 06-27-2012

I have uninstalled the printer,
I have reinstalled it,
download the drivers from the dell website
I have deleted the controllers manually one by one, and I have repeated everything twice and I still have the same problem.
