問題： 斑馬105SL打印機用串口ZPL指令打印時，當打印一些圖標時，需要發送很多的字符串，請問能否把這些圖標生成一個固定的文件，這樣以后只需發送相應的文件名就可打印相關的圖標了。請賜教！ 敏用數碼解答： 斑馬105SL實現這個功能是沒有任何問題的，但需要注意105sl的內存配置，老型號的105sl采用4MB RAM（R:），2MB閃存（E:），新型號的105sl采用6MB RAM（R:），4MB閃存（E:）。避免 條碼打印機出現圖形過大下載溢出的情況。 通常采用ZPL中的~DG指令（下載圖形）【ZTOOLS工具生成GRF】和^XG指令（調用圖形）或^IL指令（調用圖形）【^XG與^IL的區別為：是否可以對圖形進行縮放？】來完成這樣一個過程。 ~DG指令（下載圖形）格式： ~DGd:o.GRF,t,w,data d=存儲圖形的位置，可選的值：R,E,B,A o=文件名，1-8個字母數字字符 t=圖形占用字節數（bits） w=每行的字節數 data=ASCII字符串 t參數的計算公式： xz/8 * yz=t （x=圖形以mm為單位的寬度，y=圖形以mm為單位的高度，z=dots/mm為單位的打印機分辨率，8=bits/byte） 比如，8mm寬，16mm高的圖形，采用105sl-203dpi打印機打印，那么： t=8*12/8*16*12=2304 ^XG指令（調用圖形）格式： ^XGd:o.GRF,mx,my d=存儲圖形的源位置，可選的值：R,E,B,A o=圖形的文件名 mx=X軸的放大倍數，1-10 my=Y軸的放大倍數，1-10 ^ILd:o.GRF 例子： 下載圖形代碼： ~DGR:SAMPLE.GRF,00080,010, FFFFFFFFFFFFFFFFFFFF 8000FFFF0000FFFF0001 8000FFFF0000FFFF0001 8000FFFF0000FFFF0001 FFFF0000FFFF0000FFFF FFFF0000FFFF0000FFFF FFFF0000FFFF0000FFFF FFFFFFFFFFFFFFFFFFFF 調用圖形代碼（^XG）： ^XA
^F020,20^XGR:SAMPLE.GRF,1,1^FS
^XZ ^XA
^F020,20^ILR:SAMPLE.GRF^FS
^XZ 如何把圖片轉換為GRF格式： 下面介紹如何把斑馬logo轉換為GRF格式 1、Logo圖形的后綴名需要為PCX或者TIF 2、然后通過ZTOOLS工具中的Convert Graphic File功能，把PCX或者TIF的文件轉換為GRF格式的文件。 斑馬LOGO經過轉換后的GRF格式的代碼如下： ~DGR:ZLOGO,02180,020,E0000000000000000000000000000000000001A0
