# 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 utility file 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).
