Can't really determine that without seeing the DDS for the printer file.

Probably because the second record format did not specify skipping to  
a new page. It printed on the current page at the current print location

Doesn't matter. Actual print location depends on what is specified in  
the DDS for the record format being written.

Page control (i.e., skipping) specified in the DDS for the record  
format.

Nope.

Nope. Multiple pages only occur when the print position is skipped to  
a new page (or when you print off the end of the current page but  
that usually indicates a coding defect).
