About Thermal Printer Camera

<b>Pointillist</b> turns your phone into a simple instant camera for Bluetooth receipt printers. Take a photo, choose an image from your library, and print it as bold black-and-white dot art on inexpensive thermal paper. No ink, no cartridges, and no complicated editing. Just pair a compatible printer, frame your image, and print. Dither like it’s 1976. <b>Important compatibility requirement</b> Pointillist is designed specifically for Bluetooth thermal printers that support standard <b>ESC/POS commands</b>. <ul> <li>You must already own a Bluetooth ESC/POS printer.</li> <li>The printer must be paired with your phone before printing.</li> <li><b>Paperang, PeriPage, and other printers that require proprietary manufacturer apps are not supported.</b></li> <li>This app does not add Bluetooth support to USB-only printers.</li> </ul> If you are unsure whether your printer supports ESC/POS, check its manual or product listing before installing. <b>Features</b> <ul> <li>Take photos directly in the app</li> <li>Print images from your photo library</li> <li>Convert photos into distinctive black-and-white dithered prints</li> <li>Adjust image size, print width, slicing, density, and transmission delay</li> <li>Support for common 58 mm and 80 mm ESC/POS printers</li> </ul> <b>Printer setup and troubleshooting</b> <ul> <li><b>Print stops early or produces long strips of random text:</b> Enable image slicing and increase the buffer-overflow delay in the printer settings.</li> <li><b>Print contains many horizontal white lines:</b> Disable image slicing or reduce the buffer-overflow delay.</li> <li><b>Print is garbled, compressed, or too narrow:</b> Confirm that the configured pixel width matches your printer. Many 58 mm printers use 384 dots per line, while many 80 mm printers use 576 dots.</li> <li><b>Printing is slow or unreliable:</b> Use the printer manufacturer’s computer utility, when available, to adjust Bluetooth baud rate, print speed, and density. Enable Bluetooth 4 mode if supported.</li> </ul> Printer hardware varies considerably, so some models may require experimentation with the slicing, width, and delay settings. <b>Questions, suggestions, or problems?</b> Send an email to the support address listed below. Pointillist is a free project developed in my spare time, so responses may not be immediate, but I will do my best to help.
