How to obtain the origin of the printable area ?
Is the PageWidth/Pageheight relative to this origin ?
As far as I know (or how I always understood print drivers), the
PageWidth and PageHeight is the full page size (eg: A4 = 210x297mm).
No, as far as I can see, this is paperwidth and papersize.
The printable area is printer dependent. eg: my laser printer can't
print in a 5mm border around the page. Yet my inkjet printer can print
full page size. Same software was used to test this.
I know this, and it looks like this is why PageWidth and PageHeight were
introduced.
But without knowing what the origin of this pagewidth&pagesize is, these are
useless properties.
I must now resort to trial and error to draw a rectangle with sides at equal
distances from the paper borders. e.g. 1 cm from the paper edges. The
'logical' choices (as also used in the selectprinter demo) do not seem to work.
Michael.
