I have a printer connected to one PC running slackware. The printer is set up to be shared through Samba and I can print to it from my Windows laptop.
I would however like to use that printer from another Linux machine (running Ubuntu).

Do I need to go through Samba to do this or is there a better way with it being linux-linux?

Everything I've found on google relates to going from Linux to Windows unfortunately.

There is a better way. On the second machine ( client ) install cups. In cups add the printer. On my network, linux boxes find the cups share, I don't have to do anything. Could not be easier.

I believe you need the print driver on the client though.

Do I have to do anything special in the setup on the machine which has the printer installed on it?

No, as long as the printer prints locally, you are good to go. Like any network program, I would suggest you have an updated /etc/hosts file. But beyond that, nothing. Just in case you are not familiar with /etc/hosts file, here is a sample.

You list each systems IP address, followed by the hostname, and alias host name. If you are using samba, it will work much better with this up to date as well.

I found an article on the Arch wiki that describes how to share a printer on a Linux host to another Linux printer.

Hi -

You'd usually set up a printer (any printer) using CUPS on the Linux side. And, since CUPS is network-aware, you probably don't need to do anything more to share two printers Linux::Linux:

STRONG SUGGESTION:

Try CUPS first.

But don't hesitate to fall back on CUPS::Samba if you need to. And feel free to go back and try CUPS-only once you get CUPS::Samba working.

Because (as you've already noticed), it's the more common scenario. Consequently, you're likelier to get help with the CUPS::Samba scenario than with CUPS::CUPS.
