    Fault : Network printer stops printing -- 0x0000011b, 0x00000709, 0x0000007c
    Fix   : Rebuild the client's print configuration
    Source: https://jbtecwiz.com/support/win-net-printer-network

    Run as     : Elevated PowerShell on the client
    Expect     : 25 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    0x00000709, 0x00000040, or a spooler that crashes as soon as a queue is
    opened.

    HOW TO UNDO IT
    Export HKCU\Printers with reg export before clearing it; re-import to
    restore the previous connections.

    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.
