A customer reports that his LaserWriter stops printing in the middle of a
job, with a message that it is unable to print or set up a spool file.
This could be caused by using a LaserWriter with version 1.0 ROM, which
had an XOFF-XON problem (an XOFF was sent by never an XON). This resulted
in the LaserWriter not finishing its printing. The 2.0 version LaserWriter
ROM corrects the problem.
Here's how to tell what version ROM is in your LaserWriter:
1. Look at the test sheet that comes out of the LaserWriter when it's
started up.
2. On the test sheet, find the picture of a page with a graph.
3. The ROM version is shown in the lower-left corner of that picture.
4. If the number is 1.0, replace the LaserWriter ROM with the latest version.
