To compile the driver, it did: git clone --depth 1 https://github.com/pdewacht/brlaser.git cd brlaser cmake -B build -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_OSX_ARCHITECTURES=arm64 \ -DCMAKE_POLICY_VERSION_MINIMUM=3.5 cmake --build build -j8 cd build && ctest # 4/4 passed ppdc -d ppd brlaser.drv # generates ppd/br2220.ppd Build deps came from Homebrew (cmake) plus the CLT SDK for cups/raster.h. Two gotchas1. `-DCMAKE_POLICY_VERSION_MINIMUM=3.5` is required — current CMake rejects the project's old `cmake_minimum_required` outright. 2. The generated PPD names the filter bare (`rastertobrlaser`), so CUPS looks in `ServerBin` = `/usr/libexec/cups/filter`, which is **read-only…
