Print disappears from spool, never prints

Q:

I just installed a new printer and set it up like all my other printers.  When I send print to it, it  just disappears.  The JQPLOG says it printed successfully, it cleans it up but it never arrives at the printer.  I noticed the only printer language it understands is PCL6.  Is this a problem?

A:

JQP does not understand PCL6.  It can process PCL5, PCL5E or Postscript, but if there are PCL6 commands in the input datastream JQP will not process them and may "swallow" the report.
