+title: Add a remote shared printer with a couple of shell commands
+tags: [printer, CUPS, share]

+description: How to add a remote shared printer within CUPS using a couple of shell commands
+---
+
+If you happen to have a USB printer without WiFi and a computer that will
+act as server, then you can use [CUPS](https://www.cups.org/) to share it.
+
+Once you setup CUPS to allow non-localhost connections, on port 631, you can
+use the web interface for the configuration. At the time, I tried to add the
+printer from a client computer using the web interface and selecting the
+driver, just like I did on the server. I got a `Filter failed` error.
+Basically, I think that the problem was that the file got through the printer
+filters twice (see `$ man 7 filter`). To avoid this, the printer needs to be
+added as *raw* from a CLI shell:
+
+```shell
+local_printer_name="Printer"
+server_hostname="192.168.0.1"
+
+# This must be the exact same name
+# as the one reported on the server.
+remote_printer_name="Remote_printer"
+
+description="Remote printer"
+location="Connected to the server"
+
+lpadmin -p ${local_printer_name} -v \
+ipps://${server_hostname}:631/printers/${remote_printer_name} \
+-D "${description}" -L "${location}" -E
+```
+
+Please note that `lpadmin` needs root privileges.
+
+The only thing to do is to edit the variables appropriately and then do a printer test. 
+
+Recently I experienced encryption certificate problems using `ipps://` but
+everything worked fine using the plain `ipp://` protocol. If you are
+in a trusted network this shouldn't be a problem.
+
+You can now set the new printer as the default system one:
+
+```shell
+lpoptions -E -d ${local_printer_name}
+```
+
+Just like `lpadmin`, `lpoptions` also needs root privileges.
+
+In case you need to remove the printer you have to run the following:
+
+```shell
+lpadmin -r ${local_printer_name}
+```
+
+See `$ man 8 lpadmin` and `$ man 1 lpoptions` for all possible parameters.
+
+That's it...
