Job Control
Click the Job Control tab to display the Job Control tab dialog box, which
controls such options as when the PostScript header and the PostScript error
handler are sent to your printer.
m Printer Mode Lets you set up the printer to receive data in ASCII or binary
format.
m PostScript Header The PostScript header contains instructions that a
PostScript printer needs to print documents created by the driver. If
your printer is connected directly to your computer only, you can save
time by choosing the Download button to send the PostScript header only
once—when you switch on your printer. Download Each Job tells the
driver to send the PostScript header with every document. Already
Downloaded tells the driver not to send the PostScript header with
documents. Download tells the driver to send the header when you choose
the Download button.
