I hope I am doing this correctly. I am new to B4A and might be in the wrong area; but here it goes. I've been looking at the creation of PDF's and printing the same. I've been able to create and view a PDF file on my device. Next, I wanted to print it. It seemed straight forward, but I get this error every time I try to initialize the printer (My Main Module code appears afterward):
I've searched and searched for an answer and am stuck. Version 1.11 of the Printing Library is installed and Android SDK seems to be current.
