I had serveral "me too"s but unfortunately no solution. The problem
does seem to be that the HP LJ 4m can't cope with two jobs arriving
in close succession at the serial port, it loses the first part of
the second one and therefore the PostScript header. A couple of people
suggested playing around with queue depths on the terminal server, but
this didn't help. I guess the only solution is to buy another printer.
