问题：
斑马105SL打印机用串口ZPL指令打印时，当打印一些图标时，需要发送很多的字符串，请问能否把这些图标生成一个固定的文件，这样以后只需发送相应的文件名就可打印相关的图标了。请赐教！
敏用数码解答：
斑马105SL实现这个功能是没有任何问题的，但需要注意105sl的内存配置，老型号的105sl采用4MB RAM（R:），2MB闪存（E:），新型号的105sl采用6MB RAM（R:），4MB闪存（E:）。避免条码打印机出现图形过大下载溢出的情况。
通常采用ZPL中的~DG指令（下载图形）【ZTOOLS工具生成GRF】和^XG指令（调用图形）或^IL指令（调用图形）【^XG与^IL的区别为：是否可以对图形进行缩放？】来完成这样一个过程。
~DG指令（下载图形）格式：
~DGd:o.GRF,t,w,data
d=存储图形的位置，可选的值：R,E,B,A
o=文件名，1-8个字母数字字符
t=图形占用字节数（bits）
w=每行的字节数
data=ASCII字符串
t参数的计算公式：
xz/8 * yz=t （x=图形以mm为单位的宽度，y=图形以mm为单位的高度，z=dots/mm为单位的打印机分辨率，8=bits/byte）
比如，8mm宽，16mm高的图形，采用105sl-203dpi打印机打印，那么：
t=8*12/8*16*12=2304
^XG指令（调用图形）格式：
^XGd:o.GRF,mx,my
d=存储图形的源位置，可选的值：R,E,B,A
o=图形的文件名
mx=X轴的放大倍数，1-10
my=Y轴的放大倍数，1-10
^IL指令（调用图形）格式：
^ILd:o.GRF
d=存储图形的源位置，可选的值：R,E,B,A
o=图形的文件名
例子：
下载图形代码：
~DGR:SAMPLE.GRF,00080,010,
FFFFFFFFFFFFFFFFFFFF
8000FFFF0000FFFF0001
8000FFFF0000FFFF0001
8000FFFF0000FFFF0001
FFFF0000FFFF0000FFFF
FFFF0000FFFF0000FFFF
FFFF0000FFFF0000FFFF
FFFFFFFFFFFFFFFFFFFF
调用图形代码（^XG）：
^XA
^F020,20^XGR:SAMPLE.GRF,1,1^FS ^FO20,20^XGR:SAMPLE.GRF,1,1^FS
^XZ
调用图形代码（^IL）：
^XA
^F020,20^ILR:SAMPLE.GRF^FS 应是 ^FO20,20^ILR:SAMPLE.GRF^FS
^XZ
如何把图片转换为GRF格式：
下面介绍如何把斑马logo转换为GRF格式
1、Logo图形的后缀名需要为PCX或者TIF
2、然后通过ZTOOLS工具中的Convert Graphic File功能，把PCX或者TIF的文件转换为GRF格式的文件。
斑马LOGO经过转换后的GRF格式的代码如下：
~DGR:ZLOGO,02180,020,E0000000000000000000000000000000000001A0
