Help! VB.Net code only works on some printers. Not a XEROX Document Centre 440ST.

Please Help!!! I am trying to print from a List Box in VB.Net. It works on most printers eg. HP Laser Printer however, I need to be able to print it on a XEROX Document Center 440ST. It prints however the text comes out all garbled in symbols. Has anyone had a similar problem and do you know how to resolve it? My code is below. Thank you!






Private Sub Print_Load()

Dim x As Integer = lstData.SelectedIndices.Count - 1

ReDim strPrintData(x)
lstData.SelectedItems.CopyTo(strPrintData, 0)

'A new selection has been made to print reset the page counter to 0
PageNumber = 0

End Sub
