^L is a formfeed
^[ is an escape, (which I'll write as [ESC] to ease reading)
[ESC]E is a PCL RESET command
[ESC]%-12345X is a PJL prefix (usually followed by a command), for
[ESC]%-12345X at PJL EOJ
is a PJL end of job command, which tells the printer to prepare for
the next job;
[ESC]%-12345X at PJL ENTER LANGUAGE = PostScript
is a PJL language switch command (to PS, obviously).
PJL (Printer Job Language) is primarily helpful with HP printers which
have multiple personalities (i.e. PCL and PS).
Anyway, it looks to me like the entire job is not making it to samba, as
the PJL command is missing.
I would suggest printing to a file on the Win98 client and look to see if
there is more PJL code in the file the client actually created. Then
you'll need to figure out where it's gone to.

You may wish to *ADD* '@PJL EOJ', instead of using sed to remove the
'extra garbage'. I'm not sure if it matters, however. I would at least
leave the PCL Reset ([ESC]E), as this can prevent the printer from being
left in a strange state. I suppose that's what the PJL EOJ is for too...
