# 12.19. Lexmark Printers

Some Lexmark printers do not send end of job status back unless configured to do so. Here is what is needed to force this. (This capability has been incorporated into the ifhp filter.)

        There is a fix for that...it is originally from the Lexmark 4039
        series, but it still works on the Optra S 1650 machines that we
        have (and should work on the rest of the optra line).  Just send
        this little chunk of postscript to the printer once:

        -----------snip----------
        %! Postscript to set the 4039 printer into synchronous mode
        serverdict begin 0 exitserver
        statusdict begin true setenginesync end
        -----------snip----------

        Basically, it causes the printer to wait until it is finished
        printing before actually reporting that it is done.  I've got 3
        Optra S printers running with ifhp right now with no extra options
        (just defaults).
