Syntax

'Declaration
Public MustOverride Property LineChars() As Integer

public abstract int LineChars {get; set;}

public: property virtual Int32 LineChars{
    Int32 get();
    Void set(Int32);
}

public abstract int get_LineChars();
public abstract void set_LineChars(int);

public abstract function get LineChars() : int;
public abstract function set LineChars(int);

Remarks

If changed to a line character width that can be supported, then the width is set to the specified value. If the exact width cannot be supported, then subsequent lines are printed with a character size that most closely supports the specified characters per line. (For example, if set to 36 and the Point Card Reader/Writer can print either 30 or 40 characters per line, the service object should select the character size “40” and print up to 36 characters on each line.)

If the character width cannot be supported, an error is returned. (For example, if set to 42 and the Point Card Reader/Writer can print either 30 or 40 characters per line, the service object cannot support the request.)

Setting LineChars may also update LineWidth, LineHeight, and LineSpacing because the character pitch or font may change.

The value of LineChars is typically initialized to the Point Card Reader/Writer’s default line character width when the device is first enabled by the service object.

Accessing LineChars can throw the following exception:

Value	Meaning
Illegal	An invalid line character width was specified.
