Thanks for your assistance however "-plot" does not give me the same options as the plot dialogue box.
I wish to use the command line to perform the dialogue box function "Page Setup > Name > <Previous plot>" leaving all other settings as per the previous plot whatever they may have been.
But...
How do I turn off the print dialogue box and edit print settings from the command line?
I wish to do this to set-up a button on my toolbar to print the current drawing as per previous plot, then save, change the settings back to dialogue box printing and close the current drawing.
