Read of address xxxxxx This error was happening when trying to print 

and/or reprint ap checks. Resolution: There was no default printer selected 

on the PC. Once a default printer was selected, printing ap checks worked. 

This problem happened after a Windows10 update. When setting the default 

printer, there was a message about Windows not managing printers by 

selecting a default. Clicked OK on that message and set the default.
