資源簡介
客戶端安裝個軟件。負(fù)責(zé)監(jiān)控該電腦的打印動作。并把內(nèi)容轉(zhuǎn)成圖片儲存。并將圖片傳送到服務(wù)器機器上,并將打印內(nèi)容傳到服務(wù)器上面．
解決方案:
1. 先用api打印函數(shù)連接到指定的打印機.再試著用枚舉函數(shù)()獲得打印作業(yè)信息．根據(jù)信息得知打印的內(nèi)容，及當(dāng)前的狀態(tài)．
2. 獲知內(nèi)容，得知打印內(nèi)容所在的位置，再某種方式將數(shù)據(jù)導(dǎo)在圖片；再傳到服務(wù)器上．
技術(shù)問題：
１． 打印枚舉函數(shù)中找不到JOB_INFO_1 或 JOB_INFO_2結(jié)構(gòu)的定義．(已解決)
２． 怎么樣獲得打印內(nèi)容.是通過原本的驅(qū)動還是其它辦法,
其它：
文件傳給pdf打印機之前已經(jīng)存成raw格式了,應(yīng)該是從緩沖池中直接讀取數(shù)據(jù)
接下去要完成的應(yīng)該是怎么把raw格式讀出來，
具我推測在獲得打印信息的時候肯定有某個參數(shù)跟這個RAW格式是對應(yīng)的．讀出某個參數(shù)后才能再繼續(xù)讀取對RAW文件讀取
具微軟件網(wǎng)站顯示,打印機的格式應(yīng)該分成5種.raw的三種格式,text,emf(增強型圖元文件)
RAW格式指是最原始的數(shù)據(jù)
CreateDC("WINSPOOL", printer, null, ref dv);//用DISPLAY，是獲取整個屏幕的設(shè)備場景；2、用WINSPOOL，則是訪問打印驅(qū)動 返回新設(shè)備場景句柄，若出錯則為零
EMFStreamPrintDocument
實力問題:就算獲得句柄也沒有辦法接下去要做什么.(想錯了)
目前狀態(tài):EMF圖片取出來,監(jiān)控也可以實現(xiàn)了.但監(jiān)控的打印作業(yè)跟EMF圖片不知道怎么產(chǎn)生關(guān)聯(lián).而且EMF圖片讀起出來比較慢．
取ＥＭＦ圖片本身spl就已經(jīng)讀入內(nèi)存，但是有一種辦法為了要讀取圖片只能將spl文件考出來再做成emf文件.
新的思路能不能將文件
shd文件中包含了一個作業(yè)ID
RPC 命名管道
Server（服務(wù)器）
Server 系統(tǒng)服務(wù)提供 RPC 支持以及文件、打印和命名管道在網(wǎng)絡(luò)上的共享。Server 服務(wù)允許本地資源（如磁盤和打印機）共享，因此網(wǎng)絡(luò)上的其他用戶可以訪問它們。它還允許在其他計算機上的應(yīng)用程序與您計算機上的應(yīng)用程序之間進(jìn)行命名管道通信，這是用于 RPC 的。命名管道通信是為一個進(jìn)程的輸出（此輸出用作另外一個進(jìn)程的輸入）而保留的內(nèi)存。接受輸入的進(jìn)程不必是本地進(jìn)程。
