A group of French enthusiasts presented the project open printer , aimed at creating a colored jet printer with an open hardware and software filling. The device is modular and built on the basis of typical replaced parts. The printer can be assembled as a constructor and, if necessary, independently upgrade, improve or repair. Project developments, including files with electronic and mechanical components, firmware, drivers and lists of components (BOM-Bill of Materials), it was decided to distribute under the Creative Commons by-NC-SA 4.0 license, prohibiting the use of commercial purposes.
can be used in the printer (US) and HP 302 (Europe), without DRM, bindings to the manufacturer and restrictions on the re -referery. It is allowed to install one black and white or one color cartridge, as well as both cartridges (black and white + color).
The seal is maintained both on 27-million rolling paper, and on individual sheets A4 and A3. In black and white mode, printing is provided with a resolution of 600 dpi, and in color 1200 dpi.
to manage the device, the Raspberry Pi Zero W with a 1.47-inch tft screen (172 x 320) and a rotating regulator and a microctroll is used to control the device. STM32. For interaction in external devices, support for USB Type-C (for connecting to computers), USB Type-A (for storage devices), Wi-Fi 802.11ac and Bluetooth 4.1.
