Set-ShopdbPrinters.ps1 creates queues against drivers that are already present and SKIPS any that are not, so without this a freshly imaged bay silently gets no printers until a later enforcement cycle tops it up. NO WAVE GATE HERE, deliberately: waves exist because ~300 bays share one runtime share, whereas imaging runs a handful of bays at a time on the isolated PXE LAN that already moves multi-GB WIMs. Detection is the SPOOLER's driver key, not pnputil - pnputil only proves the package reached the driver store, and Get-PrinterDriver (what Set-ShopdbPrinters consults) reads the spooler, so a pnputil check goes green on a half-install. Payload is NOT in git: stage printer-drivers/ onto the PXE share like the other installer payloads.",

These two universals are 100 MB combined and resolve the overwhelming majority of the fleet's printers; the four device-specific drivers (DesignJet, Zebra ZT411, Epson C3500, FARGO card printer) are another 126 MB and are deliberately NOT staged at imaging - they belong only on the bays that have that hardware, and those bays pick them up from the runtime manifest on their next enforcement cycle.",
