My printer is HP laser jet pro p1102. It is a share printer. When I try to print this error message pops up

Unable to connect to CIFS host

Try this:

Remove printer added via ---- System Settings--- Printers

Open a terminal. (Ctrl+Alt+T).

Run it:

$ sudo -i
# apt-get update
# apt-get install --reinstall cups cups-browsed cups-bsd cups-client printer-driver-hpcups printer-driver-hpijs hplip sane-utils xsane libcups2  cups-client python3-dbus python3-notify2 python3-imaging python3-pyqt4 gtk2-engines-pixbuf  python3-lxml libsane 
# usermod -a -G lp $USER
# hp-setup

Select the printer connection type.

Select the Printer to be Configured, setup tool will display printers detected.

Select the PPD file or driver to be Used for Your Printer, usually you will want to select the recommended.
