The problem could be because of ONE out of FIVE problems listed below. Try the steps recommended and it should fix the problem.

• Cable Issue: It could be a possible issue with the cable. Try replacing the USB cable.
• Drivers Issue: Try uninstalling the printer drivers using the utility http://ftp.us.dell.com/printer/R166248.zip .Then install the drivers from the support website. Use the link: http://support.dell.com/support/downloads/driverslist.aspx?c=us&cs=19&l=en&s=dhs&os=WW1&osl=en&catid=&impid=&SystemID=PRN_ALL_A924. Also DO NOT forget to update your computer's chipset drivers before this.
  
• UAC issue: If you are using Windows Vista or Windows 7, a feature called User Access Control (UAC) would block the printer communication. Disable it, and it should work. Use the link http://www.petri.co.il/disable_uac_in_windows_vista.htm for tips on how to disable UAC.
• Print Spooler Service Error: Either the service is stopped or not started correctly. Try restarting the printer spooler services on your computer. For tips on how to restart the Print Spooler service, use the link: http://www.ehow.com/how_2319117_restart-print-spooler-xp.html

Found on another forum. For 926 this worked great.
1. Go to Control Panel - Printers : Delete 926 printer
2. Go to Control Panel - Programs and Features : Uninstall All Dell 926 related software. There should be 3 programs. (When prompted to restart, respond to wait.
3. Rename Folder C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32x86 to W32X86OLD
4. Now restart your computer
5. Reinstall 926 Software.
This worked terrific for me.

I have seen that in most of the cases (with lexmark and dell printers) it is fixed by reinstalling the printer software. Be sure that you completely remove the older drivers using the cd or using add/remove programs.
