Graph ics Co mm an d Set
L1 is a one-byte value that specifies the length of the character string. If L1 is
zero, no character string is drawn.
Parameters P1 to Pn, the character string, are one-byte values that specify the
code points (characters) of the character string to be drawn, using the currently
active character set.
Comment
Description: This order is a no-operation; it has no effect on the graphics
medium presentation space or any attribute or any current parameter. This
order can appear anywhere within the segment.
L1 is the length byte. This byte is a value between 1 and 255 and specifies the
number of data bytes that follow. Parameters P1 to Pn are the data bytes. The
printer ignores the data within the order. However, there must be at least one
data byte within this order.
01 L1 P1...Pn
End Area
Description: This order indicates the end of the boundary of an area specified
with a Begin Area order. This order does not change any other graphics
drawing attributes. However, orders between a Begin Area/End Area pair can
update the current position.
L1 is the length of the data, P1 to Pn. If no data is present, the length is zero.
Parameters P1 to Pn are optional data bytes, and if present, must be zeros.
Within the area boundaries, one or more closed figures can exist. A figure ends
either by an End Area order or by a order specifying a coordinate that implies
the start of a new closed figure. These orders include a Line, Relative Line, Arc,
Full Arc, Fillet, or Set Current Position order.
Each closed figure should close properly; its start and end points should be
identical. If not, the figure closes arbitrarily with a straight line connecting the
start and end points.
60 L1 P1-Pn
End Image
Description: This order defines the end of an image. A Begin Image order and
zero or more Image Data orders must precede the End Image order.
L1, the length, is a one-byte value that specifies the number of parameter bytes
that follow. If no parameter bytes follow, L1 is zero.
Parameters P1 to Pn are optional. The printer does not use these parameters; if
they are present, the printer discards them.
This order does not update the current graphics position.
