You most likely need to create a QApplication before using QPrinter.<br>

Those paths are different. It looks like you have two PyQt5 installs now, one<br>
in C:\Users\myname\IR-Check_Tablet\ (without QtChart) and one in c:\Program<br>
Files\Python37 (with QtChart). According to the ImportError, you're using the<br>
former.<br>
