Apple LaserWriter 12/640 PS - Manual (Page 236)

m Send Data in Binary Tells the driver to send data to the printer in a binary
format. Sending data in binary format may improve the printer’s
performance when printing images or documents containing many
downloadable fonts. The LaserWriter 12/640 PS printer can receive data in
either ASCII or binary format.
m Send Full Color Data Tells the driver to print colors on a color printer. Usually
it is best to select this option even when printing to a non-color printer.
Colors print in finer shades of gray.
m Match Colors Across Printers Tells the driver to save color-matching
information with the data for use later when the document is saved to a file
for printing on a different PostScript Level 2 printer.
m Job Timeout Sets the maximum number of seconds that the printer will
spend trying to print a document before canceling the print job. A value of
zero means that the job is never canceled.
m Wait Timeout Sets the maximum number of seconds that the printer will
wait for Windows to send data before canceling the print job. A value of
zero means that the job is never canceled.
m Margins Changes the way the printer driver reports the printable area to the
applications you use. The Default option tells the driver to report the
printable area accurately to the applications. The None option tells the
driver to report the dimensions of the paper as the printable area.
m Protocol Options Tells the printer driver whether to begin and end print jobs
with Ctrl-D. Default means it will begin and end jobs with a Ctrl-D, and
None means it won’t. If the printer is connected to your computer or
network by its parallel port, click Default; if it’s connected by its Ethernet
port, click None.
m PostScript Performance Tells the driver to build PostScript document
descriptions that print as fast as possible when Optimize for Speed is
selected. Such document descriptions might not print successfully on
printers with limited memory. Select “Optimize for Portability” to tell the
driver to build PostScript document descriptions that print successfully on
many different printers.
