Currently I'm trying to check if a printer is connected to my computer.

//the code you've tried

The error message you was getting goes here

After I get this to work, I would like to know if there is a way to detect the printer's model number or type of printer.
I looked on google and found this Url to example[^] but it is using native API's and that I don't know how to call in C#
