# HP Laser 1008a: reconstructing SPL3 printing on macOS

> The HP Laser 1008a project reconstructs the SPL3/QPDL printing path for HP Laser 1003, 1006, and 1008 devices on Apple Silicon macOS. The author compares HP and SpliX streams, documents the page and band records, and patches a page-header size mismatch. A native CUPS filter and IOKit backend send the resulting output over USB.
