Not sure if the "COMMENT" keyword above is correct (because usually
that means the PJL interpreter would handle the whole line as a
comment only -- cupsaddsmb may do the same and thererfore not trans-
late it into a *cupsJobTicket syntax.

To know for sure, one would have to see the complete PPD. The way it
works is this:

(a) you add the JCL/PJL sections to the PPD as is used by CUPS.
(b) cupsaddsmb converts these PJL lines into "*cupsJobTicket" lines
    for the PPD Samba is offering to Windows clients.
(c) once a job arrived from the Windows client, all cupsJobTicket
    lines are re-converted into PJL header lines by CUPS.
(d) pstops should leave untouch all PJL header lines it sees, and
    just pass them down the line towards the device (which is the
    only instance in the whole process chain that knows how to correctly
    interpret their contents).

Did you add *OrderDependency lines with the right values to _all_ your
"*OpenUI ... *CloseUI" sections describing the PJL lines?

Otherwise, you may have triggered a bug in CUPS and/or cupsaddsmb.
