Lisp For PDF in portrait is OK but in landscape is not fully plotted?

I am using the below LISP to plot PDF.

I use the same code for portrait ("P" instead of "L") the PDF comes out ok.

The problem is for landscape, the PDF comes out in a smaller plot area such that all 4 side part of the drawing is not plotted.

Why is that?

(defun C:PL ( / cmd file )

   (setq cmd (getvar 'CMDECHO))
   (setvar 'CMDECHO 0)
       (command
           "_.-plot"
           "Y"
           ""
           "DWG To PDF.pc3"
           "ISO expand A4 (297.00 x 210.00 MM)"
           "M"
           "L"
           "N"
           "W"
        ""
            ""
           "1=1"
           "C"
           "Y"
           "PDF.ctb"
           "Y"
           "N"
           "N"
           "N"
           ""
           "N"
           "Y"
   )
   (setvar 'CMDECHO cmd)
   (princ)
)

Perhaps change "1=1" to "Fit" ? and your window coordinates , where do they come from , I only see "" "" (two enters). So perhaps use extends?

Hi,

Try to reverse the Paper Size (W x L).

My money is on RLX answer use hard coded pts these can be outside plot area then use the "C" option centre sometimes you need just a mm or two to get that last line to work. Also Tharwats landscape or portrait.

"A3" "m"  "LANDSCAPE"  "N"   "W"  "-6,-6"  "807,560" "1=2"  "C"
