Printing to a LaserWriter IISC sometimes seems to takes a long time (for
example, one customer reported that from Excel the average is about 4
minutes per page). This relative slowness is a result of the printing
process used by the LaserWriter IISC. Rather than interpreting PostScript
commands (as is done by the LaserWriter IINT and LaserWriter IINTX), the
LaserWriter IISC creates QuickDraw to a Raster image. This is essentially
a bitmap of the screen image. QuickDraw printing is much slower than
PostScript, and no speed increases are available.
