There was another big problem with Xerox printers and interpress.
Interpress would choke when you asked it to give you 100% of the
resolution of your device.

For instance, if you had a 600*600 bitmap, and wanted to print it in a
2" by 2" square on the page, interpress would choke.  It could not
keep up with the print engine.  You would get white streaks across the
page, known as "band overruns".  This happened to me several times on
the Xerox Raven printer.

This was an example of a larger flaw in design philosophy: It must
produce fast results, not good results.  Sacrificing quality for
quantity, in retrospect, was the wrong thing to do with a laser
printer.
