I had a few mintues to test.  It appears to work but the command is asking questions each time

Printer Name - have to manually enter (defauly is always the OKI)

Plot to file - Y

Create plot file screen comes up - click save. (it then creates)

Then asked to save changes to page setup. click N is default (accept)

Proceed to plot (say No)

Command over.

Basically it works, but I have to manually enter the above responses.  Typing export and hitting enter is much much quicker.

Here is command line screenshot:
