After a few experiments it appears the pjl parser behaves very differently than
documented in the PJL technical reference manual.  It would probably be a major
project to reverse engineer the exact behavior of the HP PJL interpreter on a
particular printer and, of course, there is no guarantee that would work on all
devices.  This file demonstrates character other than '\n' may delimit a line
and pcl control codes can begin without any intervening whitespace after pjl.

We don't expect a solution to this problem any time in the near future.  Our
current pjl implementation is compliant with the documented parsing in the pjl
reference manual.
