21.4.3  Setting up Printer Server Using <CUPS> Program

 

After the installation of the <CUPS> program is complete, you need to configure the printer server installed by the <CUPS> program so that it actually works properly, and can connect to the actual printer to be printed on.

 

First, you need to grant administrator privileges for the printer to a specific user account. Here, we will grant the administration privilege to the "pi" account. Use "usermod" command as follows. This is granting user group "lpadmin" to "pi" account additionally.

 

pi@raspberrypi ~ $ sudo usermod –a –G lpadmin pi

 

<CUPS> program provides a way to configure necessary works using a web browser. To do this, open the web browser and connect printer server using default port 631 on the local host. Then it connects the configuration screen of <CUPS> program as follows.
