Postscript Options - NEC Superscript 4650 User Manual

the print quality of characters and line art by smoothing the
fine gradations along the edge of the printed image. It is best
to turn this feature OFF for color photo images.
Halftoning
If graphic images in your document do not print correctly,
use these settings to adjust screen frequency and angle. For
example, use this when screened images show a moiré
pattern.
Negative Image
If you select this, black and white values are reversed and
colors print as their complements.
Mirror Image
If you select this, pages are "mirrored" on the horizontal axis.
Scaling
You can enlarge or reduce the page image. A value of 100%
(the default) means no enlargement or reduction. A value of
50% reduces the page image to half its normal size. A value of
200% doubles the size of the page image.

PostScript Options

There are several settings you can use to customize the way
the driver processes print jobs
PostScript Output Format
These settings control the way the driver creates the
PostScript language descriptions for page images.
Optimize for Speed: Check this for faster printing. This
option may cause a problem for some print jobs if the
printer does not have enough memory.
Optimize for Portability-ADSC: Check this to ensure
that the document can be printed on any PostScript
printer. Documents may take longer to print when this
option is selected. This option is useful if the printer has
limited memory, because it creates smaller documents.
Encapsulated PostScript (EPS): Use this to print your
document as a single-page image that will be
incorporated into another file. You must also select
Output to File.

Archive Format: Use this to create a PostScript data
stream that gets stored in a file to be used later.
PostScript Header
You can control whether the driver sends a PostScript header
with each document. By default a header proceeds each sent
PostScript job. (You will not see this header, it is part of the
PostScript code.) If you are printing to your own local printer
and you will only be sending PostScript jobs you can choose
to send the header just once. The header is retained and will
be used with each job, thus slightly reducing print time.
Error Handling
You can send an error handler with each print job. Then, if an
error occurs, the printer prints a page with a message
describing the nature of the error. You or a technician can use
this information to diagnose the problem.
PostScript Timeout Values
These settings define timeout periods allowed when the
driver communicates with the printer. Enter a value from 0 to
999 seconds (32,767 seconds for NT). When zero is entered,
the printer will wait indefinitely. If your printer is shared, do
not specify a value of zero.
Job Timeout: This is the maximum number of seconds
the printer can take to print a single job. If the print job
takes more time to print than the timeout value, the
printer may stop printing and prepare to receive a new
document.
Wait Timeout: This is the maximum number of seconds
the printer will wait for data from the computer. While
receiving a print job, the printer driver may pause to
build a PostScript language description of each page. For
complicated pages, which take longer to build, you may
need to set a higher wait time.
Advanced Options
Advanced options allow you to optimize printer
performance, but generally should not be changed unless
you have specific reasons to do so. Use the driver Online
Help feature for more information on these settings.
