Thermal Printer Camera

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.
