Dialog Box: PostScript Settings [ Direct Postscript Output Dialog] [ Settings Menu]
If you are using direct output to a printer you must select the Port ; this will be either "LPTn" or "COMn". Also, if you are using a serial port for the printer, you must set or verify the data transmission parameters, such as baud, parity, etc., even if the port currently shown is the correct one. This is done in the Ports item of the Windows Control Panel (not in SHAPE).
The page size, page margins and dots per inch/centimeter should be determined by the actual printer used for final output; if these are not correct, the drawing may not be scaled and/or placed on the page correctly.
The Transfer Function is analogous to the PostScript function of the same name. The linear option is standard; modify the function to get lighter or darker shading in PostScript print-out.
Preview Color . If you select a screen preview (TIFF bitmap sub-file) in the Direct PostScript Output dialog, and if color output is selected, you can specify the type of color or pixel depth used. The Screen option uses the color depth of the the current screen display. Black-and-white PostScript output always uses a 1-bit or black-and-white screen preview.
