This is insanely cute! But please strongly consider not buying one. Especially if you have kids, or are planing to have kids.
This printer uses thermal paper, which uses BPA or BPS to develop the print, which rubs off easily [1]. BPA and BPS are absorbed into the body through the skin [2]. The amount used is 250-1000x the amount found in plastic bottles [3]. BPA and BPS are endocrine disruptors, and prolonged exposure to even low levels can result in severe endocrine and reproductive health issues (including birth defects); high levels are associated with a huge range of health issues [4].
Lobbying has clouded this issue in public perception [5]. But it's telling that supermarket cashiers have elevated levels of BPA in their systems, and the associated markers of health damage [6].
Because it was bullshit - manufacturers simply switched to BPS or other alternatives that hadn't specifically been tested yet, but were the same or worse. It turns out BPA is very hard to find a safe alternative for. And people started to realise it was bullshit.

This is quite a tangent on label printing in general, but what I really want is a computerised label printer that does mechanical punched labels, like the classic Dymos and knock-offs.
I still have and use one, basically because I don't use it enough that I need an electronic one, it'd just be handy, but I can't quite shake the appeal of the ~85% fully formed raised lettering.
I dream on an OSHW laser printer, engineered to be cheap, durable and easy to repair, with none of the bullshit manufacturers have been pushing on people for decades.
I find that giant office printers have given me a lot fewer headaches than "consumer" printers. I have a fifteen year old HP that I bought used on Craigslist for like $100, and it just magically worked upon plugging it into my router. I just use the generic Postscript driver on Macos.
I don't think that driver is open source, but I suspect that you could fairly easily get a generic Postscript printer working with CUPS.
LOL. The amount of shit I've bought off eBay and Craigslist that hasn't been wiped is significant. And that's without being totally bogus and actually putting any effort into data recovery which would surely work on most devices.
I've purchased used laptops that weren't wiped, and found fairly elaborate tax documents and other identifiable info on there that I could easily have abused.
I'm not a douchebag, so I just wiped the disk and didn't do anything with it, but I suspect that there must be an entire industry of people buying used computers or hard drives on Ebay and stealing data off there.
I just want to definitively confirm that such an industry exists. For some time, there were people buying used phones, recovering sexts, and extorting the sellers (whose name, email, phone, and address they now had courtesy of eBay).
I don’t know about repair but the $99 Brother laser printer doesn’t require any malware. You can print wirelessly from Windows/Mac/iOS without installing anything
I recently became much less enamored with my $99 Brother. There are certain paper types that it has issues pulling from the paper tray, but it can use it from the manual feed. However, the manual feed will not pull it straight and everything comes out at an angle.
If you get a cheap printer you have to buy expensive paper.
I have the worst time printing in my house because the relative humidity level is very high in the summer. In the summer when my hair is curling and curling and curling from the humidity I have prints curling and trying to come off the walls. (In the winter I complain that static electricity is making my hair stand up on end.)
You can't save money by buying 20 reams of paper on discount from Staples because the paper will soak up water and misbehave when you try to use it.
I've had my brother laser for just about 10 years now, it's been awesome, regular paper, 80# cardstock and shipping labels being no problem from tray or feed.
Labels of various types that have specific places to print on the page is the issue for me.
There's a test page that can be printed that shows alignment. The docs say to try something if it comes out skewed, but if that doesn't work then to take it to a certified place blah blah. It's clearly out of warranty, so that's a no go.
I recently upgraded capabilities as doing more than could honestly be expected of a $99 printer. It has been well worth the expense of a higher model printer.
Outside of that, I still love my $99 Brother B&W laser with scanner for anything not specialty labels. I look at it like not getting upset that a 1980s Yugo doesn't get nearly the same lap times as a 2000s model supercar
$99 Australian dollars for second hand brother MFC-9330CDW colour wifi laser printer / scanner, needed new drums ($100 for the set of four) and one toner cartridge ($15), others are low but ok.
Retails new for AU$550.
$30 second hand monochrome laser printer at work I put by my workbench in a metal fabrication workshop, outside is filthy now, have run about 3000 pages through it, so about three toner cartridges, and a new. No issues.
The software seems to be fine, light enough, unobtrusive.
I'd love to print to a Cat Printer from an iOS device via AirPrint. I see a ton of AirPlay to CUPS projects on Github, but I'm not quite sure how CUPS would be configured to simply call the Cat Printer python script. Any pointers on how to leverage CUPS or should I simply focus on an AirPrint server that directly calls Cat Printer?
It’s pretty easy to add backends to CUPS. They are just shell scripts. I’ve written a few ruby ones. Here’s an example of one I adapted for my own purposes:
I just bought a Phomemo D30 thermal label printer to label my electronics component boxes last week, and I was wondering if I can hack things to send it images from my PC instead of the phone app it comes with.
I found this repo, but I don't know if that's compatible with the D30 (the chassis pictured is of a different printer): https://github.com/vivier/phomemo-tools
Someone in Issues asked the same question, but the author wasn't able to answer for lack of hardware. I guess I need to try and/or contribute!
The "Print master" phone app is uploaded under a different brand name (QUIN LLC), and other brands also seem to sell a D30 printer. I didn't really do the work of finding out where these truly come from. Perhaps someone's got a repo up under a different name.
I've done 0 comparisons to other models in practice, but FWIW it does what I wanted it to do very well. All my stuff is obsessively well-labeled now. In fact, I labeled the printer in a mad-with-power move ... https://eikehein.com/stuff/label_printer.png
I actually just picked up the exact same printer but hadn't yet had time to see what OSS libraries were available yet. I had a previous project where I printed photos on a low res thermal printer. The images sucked, but people loved it.
I would love to learn more about the reverse engineering process for a bluetooth device like this. It's too bad there is no link to a blog or additional documentation in the repo.
You can decompile android apps, which will give mostly the original Java Classes / functions with anonymized names (class A, function b, etc...). Framework classes and methods usually stay pretty much the same.
The repo states that they reverse engineered the Android app. So potentially 0% BLE specific reverse engineering and 100% of android Java. In some cases reverse engineering java code, which decompiles relatively well, can be easier than trying to sniff bluetooth packets, potentially dealing with standard bluetooth encryption and guessing what the raw bytes do.
Can confirm, reverse engineering Android apps is decently easy if you aren't afraid of manually parsing Java bytecode (it's not that bad). I tried to reverse engineer the encryption/decryption mechanism for a digital book app (it was garbage, and I just wanted to read my books in a nice app :( ) and was almost successful.
Still a lot of work though, if it's anything like LED signs I've reverse engineered. Trying to figure out if it's length encoded payloads or delimited payloads, what obscure checksums it might use, weird encoding of images, etc. And experimenting often hangs the device, or changes it's behavior significantly.
Not reverse engineering, but I'd used free iOS/macOS apps that could inspect the traffic content. I also had access to the spec sheet from the manufacturer ("smart" BLE scale) that had where in the long payload digits were the weight, body fat, and water content, etc. Kinda fun and frustrating at the same time. If you truly wanted to punish yourself, you'd be doing this while trying to write a React Native app that communicated with the scale over BLE. :)
I bought one of these because it was advertised as usb, but it being Bluetooth-with-special-(mobile-only!)app-only meant that I returned it. Nice to see someone jailbroke it :)
Most emulators are able to export a PNG that you could then print with something like this project! They don't support using a webcam with the ROM for the Game Boy Camera though.
If you buy the real thing, there are lots of projects for extracting and printing the pictures though.
That might be fun then; have the emulator write to a thermal printer, relive a bit of nostalgia I have for the awful printouts of Pokemon characters I used to have (and might still have in a box somewhere actually).
Does anyone know how the printhead elements are able to heat and cool rapidly enough? Is it just a very thin amount of a particular alloy and a precise amount and duration of voltage? Especially the cooling off part seems like it would require a really specific material. Unless all of the heat is someone removed as the paper scrolls.
