Raspberry Pi and HP LaserJet 1020 Printer

I would like to create google cloud printer using my HP LJ 1020 Printer and Raspberry Pi. But I struggle to get the CUPS working with this printer. Finally I got it working with following instruction.

Setup Local Printer

1. Install CUPS (refer to this: http://www.howtogeek.com/169679/how-to-add-a-printer-to-your-raspberry-pi-or-other-linux-computer/)
2. Add printer, select "HP LaserJet 1020 Foomatic/foo2zjs-z1 (recommended)"
3. Although printer is added but is not working. Need to install reinstall foo2zjs from official site (http://foo2zjs.rkkda.com/). Following the instruction there.
4. Reboot Raspberry Pi
5. Try print test page from the web interface to make sure you are able to print without issue.

Setup google cloud print

1. install cloudprint service (run with sudo): http://davesteele.github.io/cloudprint-service/ppa.html

How do I change the default runlevel?

systemd uses symlinks to point to the default runlevel. You have to delete the existing symlink first before creating a new one rm /etc/systemd/system/default.target



Switch to runlevel 3 by default ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target



Switch to runlevel 5 by default ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
