[WD20] Access Violation (GPF) While Printing (4 replies)

This is only happening for one of my customers and it only happens sometimes. I do not use iInitReportQuery(). I do use iParameter(iCopies, nPrintAmount) and then iPrintReport(RPT_Label_4X3, nIdToQuery). I don't think this is an issue with printing too many copies because I believe this error has happened before when only printing 5 or 10 copies. The reports I use have 2 SQL queries in the opening of the report. I have read through the past forum posts on this, but no one seems to have a concrete solution. I've spent a lot of time on this and come up empty handed.

EDIT: The error reports the OS as Windows 8 even though my customer is using Windows 10.
