1. Pointillist is a simple instant camera to capture and print photos on the go, using your phone and a cheap Bluetooth thermal printer.
2. Try enabling image slicing and increase the buffer overflow delay in the app's printer settings.
3. A Bluetooth thermal printer that supports ESC/POS commands is required and must be paired first with your mobile device.
4. Ensure the pixel width (dots per line) setting matches the printer's specifications. 58mm printers are usually 384 dots, while 80mm printers are 576.
5. Also, look in the printer's computer drivers for a program that can increase the printer's Bluetooth baud (bandwidth) rate.
6. Most printers include PC software for configuring print speed, density, and other settings via a USB connection.
7. Disable image slicing and decrease the buffer overflow delay time.
8. Express yourself in striking black and white dots, on receipt paper! Dither like it's 1976.
9. Enable Bluetooth 4 if possible, and set the baud-rate to a higher speed.
10. Consult the printer's manual for more information.
11. Prints failing to finish or printing long strips of garbage text?
1. Well, if it's broken, I know this is the app where I should start when I get a new one! LolReally great app! I'm using it to print pictures for our students to stick in their journals, and it is just perfect for the job! Quick and easy to use, with lots of customisation options! Thank you for your work developing it!Great app, that does exactly what I was looking for when purchasing a thermal printer as a poor-mans polaroid camera.
2. I can't find a solution other than pairing again with the printer, but it always happen it again after one or two prints, I put 5 stars because it is simply speechless perfect in every aspect (not even ads)Very easy to use and it really works! I bought a mini thermal printer for my child and app which was recommended to use with it didn't work at all (UK market).
3. 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.It is unique and probably the best as a image thermal printer app, with different image dithering algorithms.
4. 5 stars would be given if pictures are also in color, not just black & white.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.
5. 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.
6. Therefore I tried to install all thermal printer app available via Play Store and this one is by far the easiest and best app to print little cute pictures.
7. I haven't come across ANY other apps for printing photos on a thermal printer that can compare to this one.
8. 10/10I'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.
9. 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.
10. Would be great if the rasterization options showed a preview, or could be changed more easily.Worked really well with the first printer in bought, but not the 2nd but I think that one is just defective.
11. The only issue is that after printing some images, the print goes wrong always starting with hundred of Chinese characters.
