Raspberry Pi: Schedule Print Job

After having a couple sets of ink cartridges dry up on me after extended non-use, I learned that I’d need to print something regularly to keep my cheap inkjet printer working. After ignoring a few of my own reminders to print a test page manually, I decided to create an automated solution using a cron job on a Raspberry Pi I already have running on my home network.

To send the file to the printer, I used CUPS (documentation here or here). I followed the tutorial here to get it installed and activate the web interface.

With the printer added, I ran lpstat -p -d to get the exact name of the printer, then lp -d <printer> <file> to send a file to the printer.

To add the weekly cron job, I ran crontab -e and added the following line to get it to print weekly at noon on Sundays:
