Thank you for your response.
Actually if I turn off the "Plot Upside Down" switch in Page Setup Manager it plots correctly in landscape orientation on my HP750C Plotter. If the switch is on, it flips and mirrors the OLE.
When I plot to my HP Laserjet 6P letter size printer, it plots correctly with the switch on or off. For some reason, I feel that it is the driver between ACLT and the HP plotter. Maybe it is a bug in ACLT 2007.
At least I have a work around.
