    Fault : Network printer stops printing -- 0x0000011b, 0x00000709, 0x0000007c
    Fix   : Fix the driver the server is handing out
    Source: https://jbtecwiz.com/support/win-net-printer-network

    Run as     : Elevated PowerShell on the print server
    Expect     : 30 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    0x0000007c or 0x00000bcb -- an architecture or dialect mismatch on the
    shared driver.

    HOW TO UNDO IT
    Remove the added printer and port with Remove-Printer and
    Remove-PrinterPort.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
