From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I just did a test with my Brother printer on Windows. I saw one port opened for the print protocol and four or five for various name service protocols (because I have a homelab and have screwed around with DNS a little too much, apparently). If you're opening half of all possible TCP and UDP ports to get the printing protocol to work, you're doing something wrong.
I said "for all print protocols", as in all the ones network printers have to support to get all possible clients to work.
