Apple LaserWriter 12/640 PS - Manual (Page 268)

m Output format 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. Select “Encapsulated PostScript” to tell the driver to build an
encapsulated PostScript document description, rather than a PostScript
description. Select “Archive format” to suppress many of the printer
settings that might prevent the file from printing. Choose this option only
if the file might be printed on unknown devices.
The following options appear only when you open the Properties dialog box
from the Printer folder:
m Assume header is downloaded and retained When checked, tells the driver to
send the document to the printer without the PostScript header.
The PostScript header contains instructions that the printer needs to print
correctly. Select this option only if you are an advanced user with
experience working with PostScript headers.
m Send Header Now Sends the PostScript header to the printer and selects the
“Assume header is downloaded and retained” option.
m Print PostScript error information When checked, tells the driver to print any
PostScript errors to the 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 Advanced Displays the Advanced PostScript dialog box, used to set data
communication protocol and format. Only experienced PostScript users
should set options in the Advanced PostScript dialog box.
