Printing WonderWare history

This isn't exactly a PLC question, but WW is related.

We are monitoring a process and if there is a malfunction during that process the WW app is to print the history trend at the end of the process. It does print as it should but it usually will not update to the current time.

This is the script that is doing the printing:

HistTrend2.ChartLength=Pot6_CureLength/1000;
HTUpdateToCurrentTime( "HistTrend2" );
PrintWindow ("POT6_HIST_TRND",1,1,0,0,0);

I do appreciate any help.
WW ver. 9.0

My guess it that the 1st two lines of your script doesn't do anything unless the trend's window is open. Try moving them inside the trend's window "On Show" script.
