Dell Printer IO942 not communicating with laptop

You've tried to uninstall and reinstall the printer driver of your printer. But still no luck. The printer still won't print. Or it would say printing but it won't finish printing.

You can try these steps:

1.Check if the firewall is blocking any printer services

2.Check what port the printer is using (reenable the bi-directional support) and if it's on online mode

3.Disable all the firewalls

4.Uninstall the printer driver and software

5.Delete any items under the ff keys:
HKLM\System\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers\Version-2

HKLM\System\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers\Version-3

HKLM\System\CurrentControlSet001\Control\Print\Environments\Windows NT x86\Drivers\Version-2

HKLM\System\CurrentControlSet001\Control\Print\Environments\Windows NT x86\Drivers\Version-3

Optional***
6.Delete any non default items under the ff keys:
Note: ONLY THE NON DEFAULT ITEMS SHOULD BE DELETED

Hello there ! 

Do you have its installation software? pls  install it again make sure the printer is not on .

After the  software installation is over  the  software will search for the added printer so the printer should be on at this time . 

If found the printer will be installed and ready to use 

If  no change  the printer registry (circuit board ) might be faulty 

good luck 

Try to reinstall the driver or change the USB cable.In worst case there is a problem in logic board assembly in your printer
