摘 要</b>：如何使用代码添加打印机 <br>
<b> 关键字</b>：打印机 Windows API <br>
<b> 类 别</b>：API

<span class="content"> 使用代码添加打印机，需要调用API函数AddPrinter，它有三个参数：<Br><Br> 1) 打印机名<Br> 2) 打印质量<Br> 3) 打印机说明<Br><Br> 以下代码把函数封装起来。你只需要提供出现在Windows Explorer中的打印机名，打印机的接口名（例如LPT1:），驱动器名和打印程序名（通常是winprint）。代码调用了API函数。<Br><Br> unit unit_AddPrinter;<Br><Br> interface<Br><Br> function AddAPrinter(PrinterName, PortName, DriverName, PrintProcessor: string): boolean;<Br><Br> implementation<Br><Br> uses<Br> SysUtils,<Br> WinSpool,<Br> Windows;<Br><Br> function AddAPrinter(PrinterName, PortName, DriverName, PrintProcessor: string): boolean;<Br> var<Br> pName: PChar;<Br> Level: DWORD;<Br> pPrinter: PPrinterInfo2;<Br> begin<Br><Br> pName := nil;<Br> Level := 2;<Br> New(pPrinter);<Br> pPrinter^.pServerName := nil;<Br> pPrinter^.pShareName := nil;<Br> pPrinter^.pComment := nil;<Br> pPrinter^.pLocation := nil;<Br> pPrinter^.pDevMode := nil;<Br> pPrinter^.pSepFile := nil;<Br> pPrinter^.pDatatype := nil;<Br> pPrinter^.pParameters := nil;<Br> pPrinter^.pSecurityDescriptor := nil;<Br> pPrinter^.Attributes := 0;<Br> pPrinter^.Priority := 0;<Br> pPrinter^.DefaultPriority := 0;<Br> pPrinter^.StartTime := 0;<Br> pPrinter^.UntilTime := 0;<Br> pPrinter^.Status := 0;<Br> pPrinter^.cJobs := 0;<Br> pPrinter^.AveragePPM :=0;<Br><Br> pPrinter^.pPrinterName := PCHAR(PrinterName);<Br> pPrinter^.pPortName := PCHAR(PortName);<Br> pPrinter^.pDriverName := PCHAR(DriverName);<Br> pPrinter^.pPrintProcessor := PCHAR(PrintProcessor);<Br><Br> if AddPrinter(pName, Level, pPrinter) <> 0 then<Br> Result := true<Br> else begin<Br> // ShowMessage(inttostr(GetlastError));<Br> Result := false;<Br> end;<Br><Br> end;<Br><Br>end.<Br><Br></span>
