Can't detect a USB connected printer: windows 7

You're trying to connect via USB but whatever driver installation you use, the printer just wouldn't print.

STEP 1
The first thing you do is to check the device manager if it detects the USB connected printer. The printer must be turned on for it to be seen in device manager. Usually found under Imaging devices

Here's how to access the device manager in Win7.


If it is detected proceed to the next step

STEP 2
Download the Print Diagnostics Utility which can be found at the sidebar of our site. It's right there on the right side. For now it's under Troubleshooting tools. Run this application and it will tell you why you can't print. That's if the problem is with the computer settings.
A Re-installation of the Software and drivers might be required.

If this still does not work go to the next step.

STEP 3
Service the printer. The Square USB port at the back of it might already be faulty. The best way to find out is to connect it to a different computer and see if it works with it. If it does repeat step 2.
