Printer ScaleHeight/Width confusion [resolved]

Ok - here goes...

I've got a deskjet and a big copier/printer. Printing stuff at TWIP position 0 (fully to the the left).

The deskjet says that the SCALEWIDTH is 10.43 inches in LANDSCAPE mode - but it manages to physically print right on the edge of the paper.

The big printer says the the SCALEWIDTH is 10.6 inches in LANDSCAPE mode - but it prints 1/4 inch from the edge of the paper.

I want to fully know the "printable" area - thus the unprintable margins and adjust for all printers - so I have some consistency here...

Any ideas?

I found this MS KB article - about using an API GetDeviceCaps to determine printer "printable" area...

KB article

Unfortunately I've got a demo tomorrow morning - so I don't have the time to research this for this week...

Anyone who might have info on this API and use for printer margins, etc - I would greatly appreciate it...

I used this KB article to develop the following couple of functions...

Here's a screen shot of what it returns

First one returns info on printable area - second one formats a string to print about that info...
