原本是使用網絡上最流行的環路網卡方式套印標簽，但是最近公司電腦換win7的，麻煩就來了。這個麻煩糾結了我兩周，中間還把標簽機搬到辦公室來測試，累死了都（估計賣廢鐵能買個好價錢）。
采用環路網卡調用時，驅動kernel32.dll時，無法連接到標簽機，但是打印測試又是ok的。個人分析情況兩種：一種就是我的zebra打印驅動方式不對（雖然后面網上下了專門win7的，但是依然不行）；一種就是Windows 9x/Me中非常重要的32位動態鏈接庫文件，屬於內核級文件，系統很可能里面的API接口變了。
基本上確認原有方法無解后，就換了個方式，即期待預把標簽機當作一般打印機使用，所以我就使用了水晶報表，照着原有格式慢慢調試，最后打印效果差強人意，還有就是打印一段時間標簽機參數都會還原回去。最后在網上找到一種使用winspool.Drv驅動標Zebra標簽機的方法，能夠使用ZPII編程語言驅動標簽機，才算是圓滿解決問題了。

我測試了一下在32位系統上使用完全能夠勝任,64位還是有問題。。。。
