You can get the information on what printer driver has been selected by
inspecting the value of the fLastPrinterName field of the TStdPrintHandler
object belonging to the view you are trying to print. The fLastPrinterName
field is changed to reflect the printer driver most currently selected in the
Chooser when a Print or Page Setup command is issued. For the LaserWriter IISC
print driver, the value of this field is "LaserWriter IISC." If a
network-based printer is chosen using the LaserWriter driver, the field
contains "LaserWriter."
