I just set up my laptop to print on my color laser printer
It's a Brother MFC-L3780CDW.
I used the local IP address like so:
socket://192.168.1.102:9100
And it just worked.
It also gave a deprecation warning.
I don't expect it to keep working.
Ah! #linux!
A #poem
But I was able to print tonight.
I now have a picture of my son.
With a cat.
He rounded out the edges with a scissors.
He's 9.
I am 47 or 48 or something.
I'm on Mastodon,

linux printer drivers!
@poleguy i have this snippet in one of our systems. It’s so dumb and so cool that it just works like that. No drivers!

You can thank Apple for that.
About 15 years ago, they strong-armed the printer manufacturers into implementing the server side of a standardized, open-source protocol stack in their printers.
Now macOS (and also other platforms like Linux) can drive any printer by implementing the client side of that protocol stack.
Apple calls it AirPrint. Everyone else calls it driverless printing.
@argv_minus_one @karlcswanson I had no idea. Very interesting.
I knew Apple was involved in some ways with CUPS. But whenever I hear AirPrint or AirDrop or whatever I think Apple and that generally doesn't apply to me.
Since I heard of Apple's approach, I've always preferred to stay away from the Apple walled garden model of computing. I'm a computer engineer now.
Staying away from walled gardens still feels like a valuable choice for me.
Wow... way off topic. Go to sleep Dietz.
Apple owns CUPS. They bought the company that made it. As far as I know, nobody else has made a from-scratch replacement for it.
OpenPrinting maintains a soft fork of CUPS https://openprinting.github.io/cups/ for use on non-Apple operating systems. Apple CUPS and OpenPrinting CUPS are both on GitHub, and their READMEs contain links to each other.
But I don't think there is any outright replacement for CUPS.
Although, now that printing is driverless and plug-and-play, the only remaining function of CUPS is print spooling and access control. So you could in theory replace it with an Apache reverse proxy or something, if you wanted to.
