In addition to the values n, m transmitted with the Document instruction, further parameters are transmitted to the Document object:

document a document created with Document
PAGE w n Size of a sheet (w columns, n lines) - see belowfor the meaning of n = 0
HEADER m Reserve m lines for heading
SPOOL k after k pages Start print output automatically
ORIGIN x y move upper left corner (character in line, column 0) to position x, y (specification in mm)
COLOR c Standard colour
COLORED print in colour
FONT c Standard font
CPI x x characters / inch (standard x=10)
LPI y y lines / inch (default y=6)
NO_CHANGE_OVER Margin pages are not printed
STRETCH fx fy Factors for scaling when transferring window objects to the print list

The following default values apply to the above parameters:

PAGE see instruction Document
HEADER according to the print lines output in the header
SPOOL Do not start printing automatically
ORIGIN 0 mm, 0 mm
COLOR BLACK
COLORED print in one colour
FONT 0
CPI 10
LPI 6
NO_CHANGE_OVER Margin pages are printed
STRETCH 1.0, 1.0

Besides COLOR and COLORED, COLOUR and COLOURED are also accepted. The specifications PAGE and ORIGIN can also be specified as CX_VALUEs, or directly as values with units. Every number without a unit is considered as a line/column specification in PAGE, and as a distance in millimetres in ORIGIN.

The indication SPOOL makes no sense in connection with print preview. If an attempt is made to display a preview and SPOOL was specified with SetParameters, an error message is displayed.
