Autodesk AUTOCAD 2006 Command Reference Manual page 897

Paper Size
Displays standard paper sizes that are available for the selected plotting device.
If no plotter is selected, the full standard paper size list is displayed and
available for selection.
If the selected plotter doesn't support the layout's selected paper size, a warning
is displayed, and you can select the plotter's default paper size or a custom
paper size.
A default paper size is set for the plotting device when you create a PC3 file
with the Add-a-Plotter wizard. For information about this wizard, see "Set Up
Plotters and Printers" in the Driver and Peripheral Guide. The paper size that
you select in the Page Setup dialog box is saved with the layout and overrides
the PC3 file settings.
The actual printable area of the page, which is determined by the selected
plotting device and paper size, is indicated in the layout by a dashed line.
If you are plotting a raster image, such as a BMP or TIFF file, the size of the
plot is specified in pixels, not in inches or millimeters.
Number of Copies
Specifies the number of copies to plot. This option is not available when you
plot to file.
Plot Area
Specifies the portion of the drawing to be plotted. Under What to Plot, you
can select an area of the drawing to be plotted.
Plot Offset
Specifies an offset of the plot area relative to the lower-left corner of the
printable area or to the edge of the paper, depending on the setting made in
the Specify Plot Offset Relative To option (Options dialog box, Plot and Publish
Tab (Options Dialog Box)). The Plot Offset area of the Plot dialog box displays
the specified plot offset option in parentheses.
The printable area of a drawing sheet is defined by the selected output device
and is represented by a dashed line in a layout. When you change to another
output device, the printable area may change.
You can offset the geometry on the paper by entering a positive or negative
value in the X and Y offset boxes. The plotter unit values are in inches or
millimeters on the paper.
