在辦公室以及校園環境中，印表機的使用越來越頻繁，然而大部分的印表機都未經控管。系統管理者無法追蹤列印的工作，並且也缺乏更進步的管理印表機方法，例如可以計算使用者的列印數量並依此作為收費依據等等。加上現在的列印伺服器大多侷限於單一平台上。在此篇論文中，我們實做了一個.NET嵌入式列印伺服器，伺服器只需經過一次編譯，就可以在多種不同的作業系統下執行。我們設計的列印伺服器可以分辨不同規格印表機進行列印工作時所使用的控制語言，包括HP PCL 5、HP PCL 6、Epson ESC/P和Adobe PostScript。伺服器使用RFC 1179的LPD協定來接收和列印工作，然後系統管理者就可以從列印工作檔案及控制檔案裡獲得一些資訊，這些資訊還可以用來做其他參考用途。我們比較不同印表機控制語言的檔案大小，並且也評估了伺服器裡不同的語言解析器在不同平台下的性能，這證明我們的嵌入式印表機伺服器可以在Windows XP、Windows CE .NET和Linux的平台下執行，並且可以促成軟體快速開發之目的，列印工作的內容也正確地被解析出來。

The use of printers is common in offices and campus environment but printers are mostly uncontrolled. Administrators can neither track the jobs printed nor manage printers in advanced method, such as charging for printing documents automatically. Additionally, the print servers nowadays are restricted on one kind of platform. In the thesis, we implement a .NET embedded print server, which can be executed on multiple operating systems with only one compilation. Our server is able to distinguish print jobs between different format of printer control languages, including HP PCL5, HP PCL6, Epson ESC/P, and Adobe PostScript. The server accepts and prints jobs through RFC 1179, LPD protocol. The information retrieved from print jobs and control files is useful for administration or for further use. We also did a comparison of sizes of jobs in different printer languages, and the performance of language parsers in embedded print server is evaluated on different platforms. This also proves that our server can run under Windows XP, Windows CE .NET, and Linux, which enables rapid development of software. Moreover, the information of jobs is revealed precisely.
