Printing via KeyIn (for Printer name)

Hello,

I was wondering if there was a way to send a key in for a specific printer...?

At the moment i have code that runs through and determines what the 'paper size' is and the 'orientation' (SEE BELOW) of the drawing then prints accordingly. My trouble is specificing a printer name (currently, we leave it blank and it prints to the default printer). I want to be able to tell it which printer to print to. What is the line of code i need, more so what is the key command? For the sake of this post, the printer is called. a3myPrinter

Current code for 'paper size' is and the 'orientation'

CadInputQueue.SendKeyin "print papername " + paperSizeVariable
CadInputQueue.SendKeyin "print orientation " + orientationOfPaperVariable

What do i need for 'printer name' (a3myPrinter)

CadInputQueue.SendKeyin "print printername " + "a3myPrinter" ?????


or

CadInputQueue.SendKeyin "print printer " + "a3myPrinter" ?????

Thanks in advance
