Thermal Printer Camera

Aptition

About this app

Pointillist is a simple instant camera to capture and print photos on the go, using your phone and a cheap Bluetooth thermal printer. Express yourself in striking black and white dots, on receipt paper! Dither like it's 1976.

Printing Tips:

• A Bluetooth thermal printer that supports ESC/POS commands is required and must be paired first with your mobile device. Paperang or PeriPage are not supported, unfortunately, because they are proprietary to their manufacturer.


• Prints failing to finish or printing long strips of garbage text? Try enabling image slicing and increase the buffer overflow delay in the app's printer settings.


• Many white horizontal lines? Disable image slicing and decrease the buffer overflow delay time. Also, look in the printer's computer drivers for a program that can increase the printer's Bluetooth baud (bandwidth) rate.


• Garbled or narrow prints? Ensure the pixel width (dots per line) setting matches the printer's specifications. 58mm printers are usually 384 dots, while 80mm printers are 576.


• Most printers include PC software for configuring print speed, density, and other settings via a USB connection. Enable Bluetooth 4 if possible, and set the baud-rate to a higher speed. Consult the printer's manual for more information.

Ratings and reviews

Really awesome. Thank you so much for taking the time to develop and publish this app! Being able to configure settings for print delay and image slicing is so useful, and I'm pretty sure this is the only app on the entire play store that allows you to choose from all the major dithering algorithms and bothers to list their names. I haven't come across ANY other apps for printing photos on a thermal printer that can compare to this one. It's free, NO ads, works great. Exactly what I need. 10/10

I can finally print a picture with my Temu purchased Mini thermal printer! Yay! This was the 3rd app I found named in reviews for the non-working app in the device instructions. Thank you for creating this super easy to setup ans use app! I had just about given up and trashed the cute little bear (or is it a dog??) printer. Oh no... it just fell off the table. Well, if it's broken, I know this is the app where I should start when I get a new one! Lol

I've installed no less than 10 different apps trying to find one that could do the simple job of printing a photo with good quality, without annoying ads or extra messages and easy to use. Neither of the 10+ apps did the job except for RawBT (more or less), until I found this one. Thank you for creating this app, it is just PERFECT, I love the possibility to change brightness and contrast and seeing the results in real time.
