Assuming you have installed the software for the printer properly (you may NOT have)....
You probably have more than one printer listed in Control Panel - Printers and the wrong one is set as the default printer - Word is choosing the default printer.
(If you don't see Printers in Control Panel, on the right side of the Control Panel Screen, choose Small icons or Large icons, rather than Category.)
If more than one printer listed is for the same model, you don't need more than one.
You DO NOT need to use Add a printer there to install a printer if it's detected by Plug-n-Play (all printers connected by a USB connection are). . Installing the software for the printer the PROPER way will automatically make the printer's model appear in Printers, although it takes a short while to appear when you initially install the software for the printer.
When a printing job fails, there is a printer icon still there in your Taskbar. You must click on that and clear any failed printing jobs before you can print successfully.
If the above info does not help, it is very common for people to install the software for a printer the WRONG way !
Follow the installation directions !
You DO NOT need to use Add a printer in Control Panel - Printers to install a printer when it's connected via a USB cable !
When you initially install the printer, usually you DO NOT connect the USB cable until you have installed the software for the printer - you may be prompted to plug in the USB cable after some of the software has been installed, or after the software has been installed and you have Restarted the computer.
Unless the instructions for installing a device tell you otherwise......
(this ALWAYS applies to printer software.....) .
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
The same applies no matter when Windows finds New Hardware !
(The following also applies if you want to re-install the software)
If you DID install drivers that way, go to Control Panel - Classic View - Programs and Features and Un-install the software you installed, reboot, DO NOT install drivers while booting.
Continue on to the desktop screen, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
If you have problems with Windows detecting the printer properly when you have plugged in it's USB cable, see this:
Troubleshooting USB device problems including for flash drives, external drives, memory cards.
See Response 1:
Check that out first.
Rarely, not all the ports on the back of a desktop case may be able to supply 500ma each.
(A printer does not require 500ma, but the following info may be helpful)
If you have a desktop computer, Note that I answered a Topic on this site where a guy had an external drive, which does require the full 500ma, connected to a port on the back of a desktop case - it would not work properly when a webcam was in the port next to it, but it worked fine when the webcam was unplugged. Ports on the back of a desktop case often have two ports connected to the same USB controller module that are ports one above the other - you could try connecting the cable to one of those and leaving the other un-used.
