Where to find the data changed by PageSetupDialog

[Just Me]

I do the code at the bottom of this, and later use:
zz = mPD.DefaultPage Settings.PaperS ize.Height
and it works most of the time. It's a long story but if I use the
printer's "Custom" size I do not always get the correct results.

Expertimenting isn't getting me anywhere I need someone who
understands the mPD options!

I know I can also get page size by
zz = mpD.PrinterSett ings.DefaultPag eSettings.Paper Size.Height
Which is the one to use??

All pages in the document use the same settings.
Where should I look for the page sizes and Dpi
set by PageSetupDialog and where should I set margins.

I'd appreciate any info,

PS
Wordpad handles the "Custom" sizes for the printer OK
so it isn't the driver.
Dim lPageSetupDialo g As New PageSetupDialog
With lPageSetupDialo g
..Document = mPD
..ShowHelp = False
..AllowPaper = True
..AllowMargins = True
..AllowOrientat ion = True
..AllowPrinter = True
..PageSettings. Margins.Top = 100 * GDI.CSingle(Tex tBoxTopMargin.T ext)
..PageSettings. Margins.Left = 100 * GDI.CSingle(Tex tBoxLeftMargin. Text)
..PageSettings. Margins.Right = 100 * GDI.CSingle(Tex tBoxRightMargin .Text)
..PageSettings. Margins.Bottom = 100 * GDI.CSingle(Tex tBoxBottomMargi n.Text)
If .ShowDialog() <> DialogResult.OK Then Exit Sub
