Printer controls specify the codes to send to the plotter.
Sends a ^D code to the printer when the plot is completed. Select this option if you are using a communication channel that uses Adobe Standard Protocol. If you are porting to another platform, remove this code; otherwise, you receive an error message when printing the file.
You probably need a ^D code to avoid a time-out error if you are plotting to a network PostScript plotter. You also need a ^D if you are plotting to a locally connected PostScript plotter through the Windows Print Manager spooler (because of a conflict with a Windows system printer).
Sends a ^Z code to the printer when the plot is completed. Some PostScript plotters require a ^Z at the end of the file.
