Gentlemen,

I am trying to print to a labelprinter. Printing goes well in principle, 
but the printer spits out an A4 size length of paper after printing a 
single label. That is a waste of about 3 labels for every printed label.

Closing in on the code :
I start creating a presentation space :
oPrinterPS := XbpPresSpace():New()
oPrinterPS:Create( oDC, {1040,742,40,40,1000,702}, GRA_PU_LOMETRIC )

Note the label size : 1040 by 741 units of 1/10 mm.
Left- and bottom-margin : 40 units
Right- and top-margin : 40 units

Then I try to force the page size to the same size :
oPrinterPS:setPageSize( {1040,742}, GRA_PU_LOMETRIC )

I then check on the paper size :
aSize := oPrinterPS:device():paperSize()

aSize then shows the following values :
{1200, 0, 0, 1040, 2970, 1229, 3508}
These values are nothing like what I expected, reading the Help on 
:paperSize().  I suspect that the cause for the paper waste lies here.

So, I don't understand the working of oPrinterPS:device():paperSize() 
and also not oPrinterPS:setPageSize(), and I cannot find any way to set 
the paper size correctly.

Is there anyone who understands the working of this stuff ?

Kind regards,
Jan Groenestein

Hi Jan:
good day.
Are you using oPrinter:newPage(), oPrinter:endPage() and/or 
oPrinter:startPage()? I am not sure if avoinding to use they you can to 
make the printer does not to skip. Other thing is that the printer must 
to use margins.

Hi Carlos,

No, none of these methods is used. I'm working on a solution, if it 
solves the problem then I will post the solution here.

Kind regards,

Jan,
this should help
