I finally figured it out . Here is the soloution in case anyone else has this problem on page 3-2 of manual
3.1 Setting the Format of Data to be Received
Before data is sent from the computer, the format (command mode) of the data sent by the application software
must be checked. The cutting plotter accepts two data formats (command modes): GP-GL (Graphtec)
and HP-GL commands. Set the command mode to suit the application used.
Setting the Command Mode
Check to confirm that the cutting plotter is in READY mode (displaying the current pen settings).
Press the (PAUSE) key to switch to PAUSE mode, and then press the (NEXT) or (PREV.) key
until the menu shown below is displayed.
Press the (ENTER) key to display the menu shown below.
Press the or key to select “GP-GL” or “HP-GL,” and then press the (ENTER) key to confirm.
To cancel the selection, press the (NEXT) or (PREV.) key.
If “GP-GL” is selected, set the STEP SIZE. If “HP-GL” is selected, set the ORIGIN POINT. If a different
command from that set previously is selected, the PAUSE mode is automatically cancelled once the STEPSIZE (GP-GL) or ORIGIN POINT (HP-GL) is set.
