Don’t try this with your printer today, if you own a printer. These Epson printers were from another era and will be around long after everyone has left Earth. Dot Matrix Forever…

🖨️ It took over a year and lots of help from Claude Code but I have now been able to create a real dot matrix printer on the web that prints from Windows 3.11 in your browser: Here's the test page: I couldn't get the LPT1 port to work but COM2 did work (the dial up model already uses COM1), the JS receives the COM2 serial data (just raw print data) and then prints it Next is to make the dot matrix printer better looking (kinda 3d like on pieter dot com) and have the paper also flowing in 3d out of the printer and integrate it on the page My idea was that it might work because we also capture the COM1 data (from the dial up modem) and send it to a Websocket as a dial up connection, so we should be able to capture the COM2 traffic too but I didn't know how, but now I do IT WORKS!! 😊

🖨️ Little progress: I generated a dot matrix printer with GPT Image 2 and then some Photopea'ing to make the paper go through And I got COM1 to work for dial up internet to (my ISP) while COM2 still works for the printer (that was a challenge) Which means I can now print anything from the internet, like Hacker News! Some todo fixes: - page should scroll out not already be there - we need some perspective so the paper slowly goes into distance - integrate it into pieter .com page fully - add a local print command so you can actually IRL print your printed dot matrix print You can try it the current WIP here:

🖨️ Got printing working on pieter (dot) com I can now print from Windows 3.11 (in 1994) to my IRL printer (in 2025) It still prints out a lot of PostScript garbage but it works Here's Hacker News live today printed via gopher:// via its dial up modem on pieter (dot) com Next would be cool to have a virtual printer on the site everyone can print to but as always I have no clue how, I guess we need to emulate a LPT1 printer port with WebSockets like we do with the COM1 port for the dial up modem

There are very few things that have higher nostalgic value than the memory of The Print Shop (Broderbund, 1984). If you had a dot-matrix printer in the 80s, chances are you used this incredible publishing program. It allowed users to easily create signs, greeting cards, banners, posters, and letterheads using its built-in clip art, fonts, and templates. And if you were the curious type, I’m sure you printed an entire page in black just to see what would happen. In case you never did, let me tell you: it was both a nerve-wracking sound and a totally drenched, soggy piece of paper in the end. (Totally worth it!) Originally launched for the Apple II and later ported to the Commodore 64, IBM PC, and other platforms, it worked with any common dot-matrix printer. Its simple interface meant even 9-year-old me could figure it out. I made covers for virtually anything, from my father's toolbox to my mother's kitchen drawers. It sold over a million copies, and became one of the most popular titles of the era.
