You need 4 pieces of information to properly set your margins.

You get the physical size of your paper using PTR.PAGRINFO.PHYSICALSIZE as Physical.Width and Physical.Height
You get the printable area with PTR.GET.PAGEINFO.PRINTABLESIZE as Page.Width and Page.Height
You get the physical offset (position of print area) PTR.PAGEINFO.PHYSICALOFFSET as Offset.Left and Offset.Top

You compute Offset.Right as Physical.Width - (Page.Width + Offset.Left)
You compute Offset.Bottom as Physical.Height - (Page.Height + Offset.Top)

Don't forget to get the TWIPS.Horz and TWIPS.Vert with PTR.PAGEINFO.LOGPIXELS - usually the same

For example if you want a border of 0.25 inch all around:

You set your Margin.Left (aka PtrX1) as Twips * 0.25 - Offset.Left & if < 0, make it 0
You set your Margin.Top (aka PtrY1) as Twips * 0.25 - Offset.Top & if < 0, make it 0

You set the Page.Break as Physical.Height - (Twips * .25 + Offset.Top).
Don't forget to check for remaining space using the Line.Height = (Ptr.Font.Height + Ptr.Font.ExtLeading)


I also use a left offset of 0.6" for pre-puched paper (3 holes)

And for Letterhead I use Top=1.75, Bottom=0.25, Left=1.00 & Right=0.97"
