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 0000000000000000000000000000000000000040 8000000000000000000000000000000000000020 0000000000000000000000000000000000000000
