	tl;dr: OpenPrinter is an open-source, repairable inkjet printer/plotter using standard HP cartridges (63/302/803) with refillable ink, a Raspberry Pi Zero W main board, and CUPS for cross-platform printing over USB-C, Wi-Fi, or Bluetooth. It supports independent black/color cartridge use, A4/A3 sheets and paper rolls with an integrated cutter, and can be wall-mounted or desk-placed. Available as a self-assembly kit or pre-assembled via a Crowd Supply campaign, licensed CC BY-NC-SA 4.0.
	HN Discussion: ↓Inkjet printing is far more complex than assumed and this is just a pre-crowdfund page without a working demo ↓The CC BY-NC-SA license means this isn't actually open source as claimed ↓Should be an ink tank design rather than relying on clog-prone refillable HP cartridges ↓Laser printers are more economical and reliable for most users, making this inkjet approach questionable ↑Repairability and DRM-free operation is a compelling pitch since it repackages existing modules rather than reinventing inkjet
