Parameter Definition Section
The parameter definition section immediately follows the macro definition section and consists of one or more lines with the following syntax.
parameter_name = value_list
The parameter name can be any character string that does not contain spaces. The compiler ignores parameter names not supported by Host Print service.
The value list can be empty or can contain one or more of the following:
A three-digit decimal value.
A two-digit hexadecimal value.
A one-char character value.
The name of a macro specified in the macro definition section.
For example, the following shows a parameter defining the control sequence to be sent to the printer to begin a new line.
NEW_LINE = CRR LFF
In this example, CRR and LFF are the names of macros specified in the macro definition section.
Host Print service currently supports the following parameters (definitions of unsupported parameters are ignored).
