I'm installing a new USB printer HP LaserJet Pro M126Nw on a laptop. The printer is installed but when I print a document it's getting stopped.

Uninstall the printer you just installed. Confirm you have the packages hplip and hplip-gui installed. If not install them from a terminal:
sudo apt install hplip hplip-gui
Then from a terminal run:
sudo hp-setup -i
Follow the setup instructions and your printer should then be set up.
