It should do "A4" big hint ! Which appears to be your size, I did say you need to change values in the code.
For A4 start with 1=1 not 1=2.
Your length is 267 your height is 188 the 6 offset is ok. Look at the values in the code for the title block size its A1 at the moment.
"Designlaser.ctb" use "Acad.ctb" or your ctb
"Your printer name" you should copy from a normal plot screen as it must match exactly.
If you want pdf's as well then duplicate the plot part but with correct setting for PDF, note you need a pdfname like D01 D02 etc again probably needs some way of reading a title name via an attribute. You have an attribute drg_no that could be used for PDF name.
Get the printing to work 1st.
Again this is sample code for an A1 title block. SO see prior comments.
(COMMAND "-PLOT" "Y" "" "DWG To PDF"
"Iso full bleed A3 (420.00 x 297.00 MM)" "m" "LANDSCAPE" "N" "W" "-6,-6" "807,560" "1=2" "C"
"y" "Acad.ctb" "Y" "n" "n" "n" pdfName "N" "y"
)
The reason code is free is that sometimes the end user needs to change a few values to make it work. Helps in starting to learn lisp.
