I have downloaded a sample application regarding PDF printing from this link https://www.syncfusion.com/kb/8767/how-to-print-pdf-documents-in-xamarin-forms-platform, however when I tried to deploy and test it in my sample android device with printer attached, it always says Print Spooler has stopped.
The following is the device info:
Model Number: T1
Android Version: 7.0
Android security patch level: May 5, 2018
Baseband version: MOLY.LR9.W1444.MD.LWTG.MPV123.P12,2018/05/23 19:40
