The construction of the print range seems to happen here:

http://opengrok.libreoffice.org/xref/libs-gui/vcl/source/gdi/print3.cxx#345

I'd play with the PrintRange property, if I am not mistaken, it comes
from

http://opengrok.libreoffice.org/xref/writer/sw/source/core/view/printdata.cxx#305

For Writer, I'd pass the current page number to the SwPrintUIOptions's
constructor wherever it is being constructed, probably in SwDocShell.
If that is correct, in SwDocShell you have GetWrtShell(), and can do the
same as

http://opengrok.libreoffice.org/xref/writer/sw/source/ui/uno/unotxvw.cxx#1511

I think it will be something similar for the other apps too.
