printserver | simple rest for receiving an encrypted POST | 3D Printing library

(Newbie question).

I am attempting to list out the PrintQueues from the Microsoft PrintQueColletion in F#. Something like this:

I am trying to set a WPF PrintDialog to use values set by the user on a form to control the basic printing options, without ever showing them a dialog.

The goal is to allow them to set their print options one time, then use those settings hundreds of times during the day without having to change them unless they decide to do so.

The code works for all printers installed on my machine other than network printers. If I select a networked printer from the list, I get the following error -

System.Printing.PrintQueueException: 'An exception occurred while populating the properties for the PrintQueue object. Win32 error: The printer name is invalid.'

The strange thing is that if I set one of the network printers as the default printer, and add logic to print unattended via a LocalPrintServer.DefaultPrintQueue being passed to a PrintDialog, this code works.

I've dissected the way printer names are being handled, and I just cant seem to figure out the correct way to pass in the networked printers.

Here's my current code (I've tried so many iterations with the same results that I've lost count... LOL).

XAML- I'm populating a XAML combo box with the list of installed printers as follows -

I have a FixedDocument that I allow the user to preview in a WPF GUI and then print to paper without showing any Windows printing dialogue, like so:

I have the following code which works very well in winforms and C#:

I'm writing a script that makes it easier for users to add a network printer. With the "listBox", it shows all the configured printers in my printserver and by pressing my "add printer"- Button, it'll automatically be added.

Now I want to do a second button, which sets a chosen device from the list as a default printer.

I only know the SetDefaultPrinter command, but I don't think that's the right one.

Here's my code:

I need to get the printer status when it is offline, below is how I am getting the status;

This is driving me crazy, I just started using chef on a fresh image (win10), and for some reason when using kitchen to test a cookbook it can not find the cookbook? tried the response to this question: Chef solo can't find cookbook during kitchen test run and it throws an error saying "Your Berksfile contains multiple entries named 'printserver'. Please remove duplicate dependencies, or put them in different groups.] on default-win-2012r2-standard-amd64-nocm" Kitchen version 1.17.0

I am trying to get the printer status for CUSTOM VKP80II printer. But the value of each property stays the same as the initial state even when their is no paper or the cap is opened. How to make this code work to get the printer status?

My application.yaml:
