Setup RPI print server with CUPS


CUPS (Common Unix Printing System) is a tool there is allowing you Raspberry Pi to act as a network printer, and the tool will of course work on other systems aswell. You can manage Classes, ques, filter and so much more with CUPS and is going t make your life a lot easier if you only has a USB printer!

Step 1. Pre-requisites

You are going to need the following items
1. Raspberry pi (Model doesn’t matter)
2. At least one printer with USB connection

Step 2. Install and Configure CUPS

The first thing we are going to do is to install cups.

Then we are going to add our existing user named pi to the usergroup lpadmin created by CUPS.

And that was it. Theoretical you have a print server now, but we need to make a few changes in the configuration to make it work. I am going to use VIM as my text editor but if you prefer another text editor such as Nano then go change vim in the command with your favorite text editor.

And go to line 6. and change localhost:631 to make it listen on all interfaces.

Go to line 32. as you can see this is where you can restrict the access to the server, go ahead and insert Allow @local right under Order allow,deny. if you are going to run into trouble later the replace Allow @local with Allow all

To be able to access the configuration files then insert Allow @local right under Order allow,deny. And again if you are going to run into trouble and see a message in the web gui then replace Allow @local with Allow all

Exit and save the configuration file. And the restart CUPS to make it load the new configuration.

Step 3. Add a printer

So close the terminal and head over to your browser and type you_RPI's_IP:631 and then you should see something similar to this
This is the CUPS WEBGUI where you easily can add and configure the server if you don’t feel too familiar with the terminal.

Well. lets get to it. so click og add printer

I am installing a USB printer as most of you guys probably are. So choose your printer under Local Printers and click continue

Fill out the needed information and make sure to check Sharing. Make sure to select the right model for the printer! if your printer aren’t listed there then you should try to see if you can find a PPD file for it instead.

And that is it! you should have a running and fully working print server now. The nex thing will be to add a network printer on you computer.
