Wspl Printer Driver: Hot

This forces a clean installation of the generic WSPL driver.

pnputil /delete-driver wspl.inf /uninstall
pnputil /scan-devices
pnputil /add-driver C:\Windows\System32\DriverStore\FileRepository\wspl.inf_amd64_*\wspl.inf

Note: Replace the path with your actual driver store location.

Generic WSPL drivers are notorious for missing thermal regulation logic. Always download the official driver from Epson, Zebra, or TSC.

| Feature | Benefit for Hot Folder | |---------|------------------------| | Isolation | A corrupt print job cannot crash the spooler or other hot folder processes. | | Sandboxed rendering | Malicious content in a file (e.g., a PDF with embedded script) has limited access to system resources. | | Low privilege requirement | The hot folder service can run as a standard user, reducing attack surface. | | Built-in XPS support | No need for additional converters; many hot folder tools can natively generate XPS for WSPL. |

Microsoft updates WSPL through Windows Update (KB articles like KB5025239). Systems lacking these updates may run a pre-2021 WSPL version that has a memory leak when handling JPEG2000 images.
