Such a shame that macOS lost all its built-in postscript support including Preview.app in recent versions :(

I didn't know that! Is it announced somewhere, even buried deep in release notes, or just one of those things that they silently decided to enshittify?
Minus the colors, they worked and look pretty good.

People must really love PostScript!

I really liked developing in PostScript within NeWS... had quite a lispy interactive feeling to it.
It was perfectly usable on a early '90s Sun Workstation so I'd love to know what performance would be like on the vastly faster machines we have now.

The printer's jammed, give them some time.
Meanwhile, more about PostScript:
John Warnock's "linguistic motherboard" and Owen Densmore's "class.ps" smalltalk-like object oriented PostScript programming system, which NeWS and The NeWS toolkit used.
Owen Densmore's work with Bill Atkinson and John Warnock on the Mac printing system, and his "linguistic motherboard" email and "Swiss Army NeWS: A Programmable Network Facility" white paper:
Check out Don Lancaster’s tinaja archive, if it’s still around. He was quite enamored with NeXT style universal postscript and wrote at length about it.

I have always been a huge fan of Don Lancaster's wizardly writing about PostScript, who not only regularly published in Computer Shopper, but also generously ran a free PostScript help line at his own personal phone number. But Woody Baker was by far his biggest most enthusiastic fan of all (and highly eccentric in personality and coding style), and he would regularly extol and evangelize Don Lancaster's virtues and ideas on comp.lang.postscript.
Once around March 4 1990, I gave Woody Baker some feedback on his comp.lang.postscript faq, including the suggesting that he might consider leaving Don Lancaster's personal phone number out of it, but he replied:
>Again, I want to thank you for your contributions. You and D. Cortesi have been most helpful. The two of you gave me very in depth feedback. I have moved almost all the editorializing to the end. I have moved the style stuff to the end. As for DON LANCASTER, I left his phone number in. Don publishes it regularly in the computer shopper, as a free PostScript help line. He is self-employed, and a widely published Author, for TAB books among other things. He says he averages 80 helpline calls a day. He also sells programs and books that he is self publishing. I can assure you, he won't mind at all.
Woody loved to talk in depth about how amazing and inspirational Don Lancaster was, and defend his well deserved honor and reputation whenever anybody criticized his work.
>True. Don lives in an APPLE II world. You are wrong, however in certain statements. He has (unfortunatly) mentioned what FLXPROC does. It happens to be critical to certain things, that several consultants are working on here and there. He knows enough not to blab some things, and jerk work out from under individuals (at least some of the time). Don has dug pretty deeply into certain areas of PS, and I have dug deeply into other areas of PS. Don is first and formost a writer. He's self employed, and extremely intellegent. I am first and formost a software engineer, and secondly a writer. I tend to write, however for clients. I'm confident that I know what FLXPROC does, and what it is good for. And I'm sure Don does also. I more or less told him about FLXPROC and he more or less told me what it does. After first quarter 1990, some things will be essentially worthless as consulting info, and will rapidly become public knowlege. I don't applogize for keeping the lid on some things. I'm a bit of a mercenary in a way. I like consulting.

Lo and behold, the instant conversion of any toner image to real ink in stunning colors!

My boss, many years ago, talked about the time he programmed a printer to act as a web server using Postscript. I never asked what happened to other print requests while it was running.

They were silently sent to the client browsers... ;-)

They were routed to the integrated time machine in PS, and sent to the year 2026 when they would be rendered in mobile phones, then the bitmaps would be sent back in time to your boss's printer.

This is pretty sweet. I wonder if this is better than running pdf.js.
I just recently needed jbig2 image support in my web app and using pdf.js wasn't gonna work and be too slow and the wrong interface anyway, so I took the source code for the jbig2 decoder and vibe coded a converter that outputs 1 bit pngs. After some manual culling of code I got the wasm module down to 27kb with no glue.

Dropped a .ps in there, it's just stuck "rendering".

postscript hacks are fun! the encryption on Type 1 fonts in 1987 was broken by Harvey Grosser, an ex-IBM System 360 coder, in Palo Alto. NeWS was bad NeWS to many, with a minuscule user base at its peak. Meanwhile, every print publication in existence was faced with "do or die" in digital production. Many ended with the latter, many years later.

Sun NeWS in the browser would be cool as well.
