[名称] 图形命令
[格式] {command} {width} {height} {x} {y} {data}
[说明] {command}：选择下面指令
EXPANDED-GRAPHICS (or EG): 打印扩展图形
COMPRESSED-GRAPHICS (or CG): 打印压缩图形
{ width }:图像宽度，以字节为单位
{ height }:图像高度，以点为单位
{x}： 水平起始位置
{y}: 垂直起始位置
{data}: 图形数据
二值位图可以通过图形命令进行打印。使用扩展图形指令(EXPANDED-GRAPHICS)，
图形数据为ASCII 码，如实例所示。如果想要图形数据减半则需要使用压缩图形指令
(COMPRESSED-GRAPHICS)，图形数据为直接的十六进制数据。当使用CG 指令时，
每一个8 位的字节表示8 点的图形数据，当使用EG 指令时，每两个字节(16 位)表示
8 点的图形数据。EG 的效率为CG 的一半。
