    Printing to a raw printer from DOSBox

Summary


Although DOSBox offers printing support, the documentation is sparse and most articles refer to printing on a Windows host.
Using DOSBox 0.7.4-3 I was unable to get printing working, so I'm using DOSBox-X instead.
Using Ubuntu 20.04 and a fork of DOSBox called DOSBox-X, printing can be configured as follows.

    PowerShell QZ Tray Session Stealer

Custom session stealer for Windows fast user switching

For a pure Batch solution, see here instead: https://gist.github.com/tresf/ff91bd29f1f6846c13bf6f8bc255ab55

Problem


QZ Tray is a singleton application, so only one instance can run at a time.
Windows fast-user switching feature leaves applications running when a new user signs onto a shared workstation
QZ Tray can "steal" the instance, however this is retroactive and places a burden on the user
