    Hello,
    I'm trying to use Ghostscript via Autocad command line using Autolisp programming. The goal is totake multiple pdf's in a folder and create one pdf. I have the lisp writing the command line but it fails.
    Here is what the autolisp file produces at the command line.

    -sDEVICE= pdfwrite -dBATCH -sOutputFile=F:\Quick Plots\temp\20220617-TEST.PDF DP-L1.pdf DP-DP5.pdf DP-DP4.pdf DP-DP3.pdf DP-DP2.pdf DP-DP1.pdf

    Why is failing?
    (Error: /undefined in -sDEVICE=pdfwrite.)

    You have a space between the "-sDEVICE=" and "pdfwrite" but the error
    seems to show it is ignoring the space.

    I don't see that the command starts with "gs" but I'm not a Windoze user.

    Try "gs -h" and see if "pdfwrite" is listed under "Available devices:"

    You might want to use the pdfwrite2 device.

    There is no pdfwrite2 device, there is ps2write but that outputs level 2 PostScript.

    I can't see any way to get that from your stated command line. The space between -sDEVICE= and pdfwrite should produce an 'unknown device:'
    Ordinarily that ouwl read something like 'unknown device: devicename'
    but in this case it is blank.

    Can you quote the entire back channel output please ?

    Stab in the dark, but the error makes it look like the PostScript interpreter is trying
    to execute the command line as if it were PostScript code. Maybe autocad is piping
    directly into a running ghostscript instance and you'll need to use some other interface in Autocad to change the way ghostscript is being invoked (assuming the
    earlier guess is correct).

    My bad then, sorry for getting them confused.
