I’ve got a prototype of my hardcopy simulator going. I’m typing on the keyboard and the “display” goes to the printer:

https://movq.de/v/56feb53912/s.png

https://movq.de/v/235c1eabac/MVI_8810.MOV.mp4

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see what’s currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth … it’s not ideal.

I got that idea of moving back/forth from Drew DeVault, who – as it turned out – did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)

But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. 😍

(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. 🤪 And ls insisted on using colors …)

@bender@twtxt.net That is a noble goal. We can talk about that – as long as it doesn’t mean giving up essential freedoms like choosing which software you can run on your device (without having to ask someone for permission).

@prologic@twtxt.net I’m not smart enough to answer that question. 😅 Certainly feels like unregulated capitalism. Governments being too slow and/or unwilling to intervene … It’s a mess.

@thecanine@twtxt.net I sure hope there’s going to be push back. Is it going to happen, realistically? I don’t know.

@prologic@twtxt.net Yes, this is another instance of restricting “personal” computing. You won’t be able to install arbitrary software anymore (“sideloading”, as they call it).

It’s not unique, it’s not new. Boiling the frog alive.

We’re heading towards this: https://www.gnu.org/philosophy/right-to-read.html

Since nobody is going to push back on this (I don’t even know if that would be possible), this is going to be a reality on every platform sooner or later.

I’d guess in 20, 30 years, there won’t be “PCs” anymore. No more home computing, no more “I just write my own software”. You won’t own devices anymore, it’ll all be rented and the landlord will tell you what you can do with it.

I hope that I’m wrong, but given where we are today, I don’t think that I will be.

@prologic@twtxt.net Anything above a couple hundred Euros. 😅 The current Epson LX-350 appears to be not that pricey, though. 🤔

I mean, what do you want to do with it? If you want to use this as an actual printer for daily use, I’d get a laser printer instead, because they’re very reliable and the print quality is top notch.

I got my dot matrix printer mostly for experiments and nostalgia, so I wouldn’t want to pay something like 300-400€ for it.

@prologic@twtxt.net It’s quite similar to how escape sequences work in a terminal. ASCII text is printed as ASCII text and then an escape sequence can make it bold or underline and so on. Other escape sequences allow you to say “the following $n bytes are part of a bitmap image”, and then this gets printed at whatever the current position is (somewhat similar to SIXEL in a terminal).

It’s just that the units are a bit weird, because this is all done in bloody inch. 😅

@prologic@twtxt.net Here’s one: https://github.com/vmykh/printer_labs/blob/master/escp2ref.pdf

@prologic@twtxt.net Yeah, those POS thingies are similar. There’s “ESC/POS” as a variant of “ESC/P”, if I’m not mistaken.

All I can say is, when I go to big stores like Amazon, then I have trouble finding “traditional” dot matrix printers for use at home. 😅 Epson still sells them, but they’re more expensive than my laser printer was. So yeah, they still exist, just expensive, by the looks of it.

@thecanine@twtxt.net That’s cute. 😃 (Why Clippy, though? 😅)

@prologic@twtxt.net Hmm, good question. I haven’t checked the market, I got mine from someone I know. But to be honest, I’d suspect that buying a used one is actually your best shot, because there is virtually no market for these devices anymore, meaning new ones are very, very expensive. 🫤

FWIW, I have an OKI Microline 3390eco. Good thing is, you can still buy new cartridges for it.

If you want to buy a new device, check if it supports the “ESC/P” standard. That’s very widely supported.

Should I go on a tour with these hot air balloons some day? Not sure if it’s scary as hell. 😂

https://movq.de/v/3e26ec9a71/IMG_8800-edit.jpg

This is why I love tech from that era.

Write bytes to a parallel port and stuff happens. If it’s just ASCII bytes, then it will print ASCII text. Even the simplest programs can use a printer this way.

With a little bit of ESC/P, you can print images and other fancy stuff. That’s what I did this morning – never worked with ESC/P before, now I can print images. It’s not that hard.

Hayes-compatible modems are similar: Write some AT commands to the serial port and the modem does things. This isn’t even arcane knowledge, it’s explained in the printed manual.

Maybe I’m wearing rose-tinted glasses here, but I think with all this old stuff, you get useful results very quickly and the manuals are usually actually helpful. It’s so much easier to get started and to use this hardware to the full extent. Much less complexity than what we have today, not a ton of libraries and dependencies and SDKs and cloud services and what not.

@lyse@lyse.isobeef.org Aww, yeah. 😍 (Reminds me, I haven’t paid attention to the sunset in quite a while …)

@lyse@lyse.isobeef.org When/if I can pull it off, there will be videos! 😅

I never used hardcopy terminals, either. We did have a dotmatrix printer, but that was just used as a regular printer.

Inkjets, I don’t know. They were pretty fascinating and cool when they came out. A lot faster than dotmatrix and obviously quiter. They never gave me much trouble, actually. But I switched to a laser printer long before crap like DRM’ed ink cartridges became a thing.

Here’s an interesting thought/angle on this topic:

gemini://gemini.conman.org/boston/2025/08/21.1

A further check showed that all the network blocks are owned by one organization—Tencent [4]. I’m seriously thinking that the CCP (Chinese Communist Party) encourage this with maybe the hope of externalizing the cost of the Great Firewall [5] to the rest of the world.

Sooooooooo, things happened, and I now have a dot matrix printer again. 😍😂

(One of the end goals is to simulate a hardcopy terminal on my old box. I’m waiting for another cable to arrive, I don’t have USB there. And then use ed(1) like it was meant to be used! 😅)

@lyse@lyse.isobeef.org @prologic@twtxt.net It’s too real, isn’t it? 🤣

The GPG signatures of my software tarballs have been wrong for years (because I’ve been using rsync wrong, funny enough, it wasn’t a GPG issue) and nobody ever noticed. (They still are wrong at the moment, because I haven’t pushed the fix, yet.)

This confirms that this is just a total waste of time. Nobody ever checks this. Maybe this matters if you’re a distro, but why even bother as a single person …

@thecanine@twtxt.net Wow. I’m not an artist in any way, but I have tried to make icons for programs or fonts every now and then. Making something that is still recognizable at so few pixels is hard. Hats off!

@kat@yarn.girlonthemoon.xyz If you’re willing to ignore that it’s proprietary software, then Windows used to be pretty good. Like, 25 years ago. After Windows 2000 (or maybe XP) it went downhill fast. Kind of makes me sad, actually. 😂

Ah, so apparently they don’t like writing manpages anymore and instead use XML:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/apt.8.xml

And then they use XSLT on top and what not:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/manpage-style.xsl.cmake.in

It’s not even explicitly blue:

Abstractions upon abstractions upon abstractions.

@kat@yarn.girlonthemoon.xyz Oh no. 😨 Backups! We need more backups!

You can explicitly use colors in manpages. I saw this in the apt manpage of Ubuntu recently, which, for some reason, uses blue text in one place:

https://movq.de/v/de5ab72016/s.png

Makes little sense to me. I’m glad that most manpages don’t do this. I wouldn’t want unicorn vomit all over the place.

Using colors can be done using the low level commands \m and \M:

.TH foo_program 3
\m[blue]I'm blue\m[], da ba dee.
\m[red]\M[yellow]I'm red on yellow.\m[]\M[]
This is quite horrible.

@bender@twtxt.net This should be a core feature, no configuration required. 🤔

@kat@yarn.girlonthemoon.xyz On the one hand, all these programs have a very long history and the technology behind manpages is actually very powerful – you can use it to write books:

https://www.troff.org/pubs.html

I have two books from that list, for example “The UNIX programming environment”:

https://movq.de/v/c3dab75c97/upe.jpg

It’s a bit older, of course, but it looks and feels like a normal book, and it uses the same tech as manpages – which I think is really cool. 😎

It’s comparable to LaTeX (just harder/different to use) but much faster than LaTeX. You can also do stuff like render manpages as a PDF (man -Tpdf cp >cp.pdf) or as an HTML file (man -Thtml cp >cp.html). I think I once made slides for a talk this way.

On the other hand, traditional manpages (i.e., ones that are not written in mandoc) do not use semantic markup. They literally say, “this text is bold, that text over here is italics”, and so on.

So when you run man foo, it has no other choice but to show it in black, white, bold, underline – showing it in color would be wrong, because that’s not what the source code of that manpage says.

Colorizing them is a hack, to be honest. You’re not meant to do this. (The devs actually broke this by accident recently. They themselves aren’t really aware that people use colors.)

If mandoc and semantic markup was more commonly used, I think it would be easier to convince the devs to add proper customizable colors.

Problem is, hardly anybody knows this, because you configure this by … drumroll … overwriting TERMCAP entries of less in your ~/.bashrc:

export LESS_TERMCAP_md=$'\e[38;5;3m'      # Bold
    export LESS_TERMCAP_me=$'\e[0m'           # End Bold
export LESS_TERMCAP_us=$'\e[4;38;5;6m'    # Underline
    export LESS_TERMCAP_ue=$'\e[0m'           # End Underline
export GROFF_NO_SGR=1                     # Needed since groff 1.23

Speaking of manpages:

“Man pages are great, man readers are the problem”

https://whynothugo.nl/journal/2025/04/09/man-pages-are-great-man-readers-are-the-problem/

mandoc is nicer to read/write than the man macro package and, most importantly, it’s semantic markup.

HTML output is a bit broken in GNU groff, though (OpenBSD on the left, GNU on the right):

🤔

Still, I’m inclined to convert my manpages to mandoc.
