If the first time you can use it, then the problem may not be the compatible problem. How about installing the latest USB printer controller or checking the anti-virus software on your computers? How about the drivers of your printer on your computer?

The first time after install it, only print test page has printed once.

I tried these steps yesterday
- I removed the printer software completely
- restart computer
- disable antivirus
- reinstall updated printer drivers

And the printer doesn' work at all.

After thart, I tried to uninstall the tp-link usb printing software, and reinstall the printer software again, to connect the print directly to the computer

But the printer still not work....

En.....The computer connect directly to the printer, the printer also does not work? This could be the printer driver problem on your computer. Connect the printer directly to the computer does not require the TP-LINK software but the software from HP.

Sorry, but I need to disagree

I have 4 computers in my house, and only 2 I have installed TP-LINK USB router.

The others 2 computers are working perfectly.

The 2 computers where I have installed TP-LINK USB router stop to print at all, even after I fully remove the TP-LINK software, all printer drivers, and reinstall HP Printer drivers again.

This software appears to be bad developed and probably damaged my Win7

Several wireless routers include a feature that allows you to plug your printer directly into the router to share it over your wireless network. While this should work without trouble most of the time, you may occasionally run into problems stemming from a configuration issue.
