The response center told me that the page level recovery was broken on the
lpq printers, not so much that it's a different PJL version. We don't see
the problem with reprinting going to laserjets.

They also said that the %200 & %300 carraige controls cause problems with
printing to page printers.

Did you try setting "SERIAL_PRINTER_SIMULATION=TRUE" using patch MPEKXF7B
and the LPQ printers? The say this runs the data through a different spooler
that acts *MORE* like the serial/hpib printers.
