A macro close-up of an inkjet printer at work is drawing attention, showing in fine detail how the print head moves and deposits ink onto plain paper. Viewers are sharing and commenting on the surprisingly intricate mechanics behind an everyday office device that most people never see up close.

Baishida, a desktop 3D-printer startup, has raised angel-plus round funding, according to TechNode. The investment will support the company's consumer and prosumer desktop 3D printing business as it moves from early development toward scaled production. Details on the investors, the amount raised and how the proceeds will be used have not yet been disclosed. The round signals continued investor interest in affordable 3D printing hardware.

Developer Xuan-Son Nguyen has released ESP32-S3-based firmware that adds AirPrint and AirScan support to older Canon printers limited to USB connections. A hardware tweak is required: bridging a 5V pad so the printer detects a connected cable. The project highlights how cheap microcontrollers can extend the life of aging hardware and has drawn attention in maker and open-source communities.
