dictionary AutoMediaType is a boolean that controls the MediaType entries in the
InputAttributes dictionary in the pagedevice dictionary.
True MediaType entries in the InputAttributes dictionaries cannot be
modified by the user. The values are confined to values known by
the printer operating system.
False MediaType entries in the InputAttributes dictionaries can be
modified by the user.
EdgeToEdge is a boolean which determines if there should be an unprintable
area on the page.
True Print to the edge of the paper.
False Do not print to the edge of the paper (default).
DefaultPoliciesPageSize is an integer which equals the PageSize parameter in
the Policies dictionary unless PageSize is set to 23; in that case,
DefaultPoliciesPageSize equals the PageSize parameter value before it was set
to 23 or equals 0 if the PageSize parameter is initialized to 23. For more
information on PageSize, see page 4-58.
SubstituteSize allows for the substitution of A4- and Letter-size print materials,
and A3- and 11x17 inch-size print materials for each other when one size is not
installed.
Note: For size substitution to occur, the substituted print material and the
requested print material must be of the same paper type.
The following values are supported:
/Off No size substitution is performed.
/A4-Letter If A4 is requested but not installed and Letter is installed, Letter
is substituted for A4. Or, if Letter is requested but not installed
and A4 is installed, A4 is substituted for Letter.
/A3-11x17 If A3 is requested but not installed and 11x17 is installed,
11x17 is substituted for A3. Or, if 11x17 is requested but not
installed and A3 is installed, A3 is substituted for 11x17.
/All Both size substitutions are permitted.
Note: When the size substitution occurs, the page is scaled to the size of the
requested print material.
The DefaultPoliciesPageSize value is used as the effective policy when:
•The SubstituteSize parameter is not set to /Off and a size substitution cannot
be performed.
•The PageSize parameter in the Policies dictionary is set to 23.
Notes:
• If SubstituteSize is set to /Off, the effective policy is the value of PageSize.
• If SubstituteSize is not set to /Off and a size substitution is possible, the
effective policy is 3.
