My understanding of the SETPRC() function is that it allows you to reset 
the current print position (row,col).  For instance, if you send a 
printer initialization string to the printer with an @...SAY, then write
your first report line with an @ 0,0 SAY ...., you will get a page eject
because after the SAY of the init string, your current position is equal
to the number of characters in the init string.  In order to print at 0,0
you will get a page eject.  However, if you first do a SETPRC(0,0) before 
printing the first line, then the internal print position is at 0,0 so no eject is required.  I hope I am not misleading you, by giving bum
info, but this seems to be the way it works for me.
