What’s a cheap but ok thermal printer? The brand mentioned in this repo? I wanted to setup https://www.colonnes.com but their recommendations were quite expensive.

I bought a Zapos ZA-E200L in South-Africa for $65 [0]

It was configured with a fixed IP/subnet/gateway and no DHCP, which took an hour or two to debug and reconfigure. Been a dream since then: prints really fast and cuts properly. OP's project works well to print todo's.

The TL;DR is that it's a physical kanban board mixed with a time clock. I place them on a ticket rack hanging on the wall above my monitor. It like the ones you see at restaurants... extruded aluminum... filled with marbles... slot on the bottom. If my board is full, I can't (or at least shouldn't) accept more work. It also is an immediate reminder of what needs to be done. The physical process of marking a ticket do…

In that case... how much is 14 feet of this ticket rack? ;-)

According to https://www.amazon.com/American-Metalcraft-Silver-Aluminum-3... about $180

I actually use my printers thank you very much. Even bought one of those bank teller slip printer things and a few boxes check-sized slips. I use them for time tracking and todo list. I didn't go totally crazy, though, and stopped before getting too deep into "...and then OCR them using the check scanner" because I remembered I was already keeping track of start/stop times in a database when printing the slips.

Can you share more about this workflow? I have only recently started to appreciate how my special blend of adhd can work best with there's a physical component to actually _seeing_ the work to be done vs stashed away in a jira, exclusively.

Also... the way I work with it is pretty simple... just three perl scripts... tsta, tpau, and tend. They take a single argument... just a single string I call a tag. Usually something like a jira ticket id, but it could be something more descriptive. Keeps track of it in a sqlite database. The end part moves the record to the archive table, prefixing the start date and time to the tag so I can reuse tags for routine work tasks and that it's also more obvious when I run a report.

Fun fact... the original implementation was in OpenQM, that is, a PICK-style system.

Sorry, could you link me to the printer you're using? Does it work with CUPS? I like this idea.

(Thank you)

It’s funny, after all the work that was done to decouple content from presentation, 90% of the markup I’ve seen in every codebase this decade is using Styled Components anyway, which commingles them in the source code anyway.

Oh man... the popularity of the tailwind css framework. I have big-o Opinions on that, but screw it, if it helps people get things done quickly, then I'm all for it. The semantic xml/html dweebs set us back a solid decade.

Indeed, I can't think of anybody who prefers to

The main slip printers I use are the Addmaster 7100 and 7200... they're the same printer but use different cartridges. You can find them cheap on ebay, or at least you could. They speak their own little dialect that as far as I know isn't supported by cups as shipped. Even then, cups wouldn't be a good choice since there's a little more back-and-forth than just blasting out data to the printer. Same goes for other printers that support ESC/POS... it's not entirely the same as ESC/P and when you get into slip/validation printing you have to do a little more work on the software side.

would be cool if it supported basic html/css

That's the approach I used for my thermal printer based project. Render HTML/CSS to B/W Image and then print it on the thermal printer. https://sales-and-dungeons.app/

Incredible project! Thanks for sharing

I think this further proves that the hypothesis of decoupling content from presentation is flawed. The question is how many more data points do we need before we admit that?

Yes, iirc the concept wasn't to decouple content and presentation but to decouple semantics from presentation in order to re-present content in different media in that medium's native representation of a particular semantic. However, many things are not much different in different media, a headline is a headline. And other things like "emphasis" can have cultural differences even within the same media, like being bol…

I suppose to a limited extent, that being “articles” in the typical sense, the strategy might be said to have some modicum of success. I’m sure many CMSs store articles as mostly “plain” HTML and regurgitate the same, directly into a part of the final HTML document, with actual normal CSS rules styling that.

I... thought dot matrix printers were some of the worst for releasing particulate matter into the air? Especially ultra fine particles?

I can't find any information regarding this.

Thanks, you're right, a quick google shows nothing... I could've sworn reading about how they're very bad... perhaps I was misremembering with standard printers?
