Epson ActionLaser 1600 - Manual (Page 49)

You can also specify that EpsonScript convert TrueType fonts
to bitmaps before printing them. Converting TrueType fonts to
bitmaps saves some printing time when you are printing
documents that contain a lot of bitmap graphics and only a few
TrueType fonts.
Specifying memory usage
You may encounter printer memory problems when printing
large documents that contain many downloaded fonts. To
resolve memory problems, EpsonScript provides two options
so you can specify memory usage:
Virtual Memory. This option increases the amount of
virtual memory your printer has available for storing fonts.
Clear Memory per Page. This option clears all downloaded
fonts from printer memory after each job is printed. This
frees up memory for the next print job.
Graphics settings
EpsonScript allows you to specify the following graphics
settings:
Resolution. Can be 300 or 600 dpi. The higher resolution of
600 dpi produces the sharpest images. However, if you are
encountering printer memory problems, reduce the
resolution to 300 dpi.
Halftone Frequency. Specifies the line screen. The value
you select here depends on the resolution of your image
and the resolution capability of the output device. If you
are using 600 dpi, increase the halftone frequency (line
screen) to at least 110. For 300-dpi output, an 85-line screen
is usually sufficient.
