firstPage

Set the first page to print.
[read/write property] firstPage([out, retval] int *page) firstPage([in] int page)
This property sets the first page to print, and lastPage sets the last page to print.

This is a simplified form of the pages property. If the pages property is set, the values of firstPage and lastPage will be ignored.

resetParams resets this to its default value, which is to start printing with the first page.

VB6:
pdf.firstPage = 10 pdf.lastPage = 20
