Assigning a printer to a bay is useless if the bay cannot install it, and the fleet data says why that mattered: 42 of 44 printers could not resolve a driver. This is the delivery half - the drivers themselves, staged once per bay, so that creating a queue never waits on a download. Install-ShopdbPrinterDriver.ps1 does one driver: trust the package's signer, then pnputil /add-driver, then Add-PrinterDriver. Install-ShopdbPrinterDrivers.ps1 does a site's whole set from drivers.json, and answers a compliance question with -TestOnly, which is what makes it a clean DSC Script resource rather than a fire-and-forget install. Deliberately SEPARATE from assignment. Drivers are large, near-identical across a fleet and change rarely; assignments are small, per-bay and change often. Staging the set in the GE-Enforce common scope means the assignment client only ever creates a queue - it never fetches a 48 MB package while somebody is waiting to print, or discovers the share is unmounted at the worst moment. THE SIGNER TRUST STEP IS THE WHOLE TRICK, and it took a real driver to find it. certutil -addstore on the .cat file satisfied the Xerox package and failed every HP INF with "The publisher of an Authenticode(tm) signed catalog has not yet been established as trusted" - a coin toss, not a mechanism. The certificate is now extracted with Get-AuthenticodeSignature and added to Trusted Publishers, for every catalog under the package rather than the first INF's neighbours. On a locked bay there is no prompt to answer, so the old failure was silent. Verified on Windows against real packages, not by reading: all six drivers this site needs install through the script, a second run is a no-op, a wrong driver name fails with the names the package actually offers, and the DSC cycle behaves - TestOnly exits 1 on a clean box, install exits 0, TestOnly then exits 0. The packages themselves stay out of git: they are licensed vendor binaries, and they belong on the share beside the other imaging payloads. DEPLOYING-DRIVERS.md carries the GE-Enforce entry, the DSC configuration and the Intune shape, plus the constraint that has cost a session before: the SFLD share is mounted only during the enforcement cycle, so this runs as a manifest entry and never as its own scheduled task.
