VC打印机编程之两篇有用的文章

vc设置打印机模式并预览打印  

调用打印属性对话框：
if(::OpenPrinter("Adobe PDF", &hPrint, NULL))
{
::PrinterProperties(m_hWnd, hPrint);
::ClosePrinter(hPrint);
}
注：通过EnumPrinters可以枚举全部的本地、网络打印机信息，通过指定以上的方法，可以打开打印机属性对话框，建议通过以上方法修改打印机固定属性，比较安全。
枚举打印机
需要调用两次EnumPrinters函数，第一次的到结构体的大小，第二次得到打印机列表
DWORD dwNeeded, dwReturn;
// 得到结构大小
BOOL bl = ::EnumPrinters(PRINTER_ENUM_LOCAL | PRINTER_ENUM_CONNECTIONS, NULL, 4, NULL, 0,&dwNeeded, &dwReturn);


// 得到打印机设备列表
PRINTER_INFO_4* p4;
p4 = (PRINTER_INFO_4*)malloc(dwNeeded);
::EnumPrinters(PRINTER_ENUM_LOCAL | PRINTER_ENUM_CONNECTIONS, NULL, 4, (PBYTE)p4, dwNeeded,&dwNeeded, &dwReturn);
for(int i=0;i< div> < dwNeeded;i++)
{
TRACE("This is printer name : %s\r\n", p4[i].pPrinterName);
}
// 注意以上代码，NT以上系统支持，98不支持
最简单的一段打印程序
流程：
1、得到默认打印机名称（如果你不打算更改打印机的话，就不需要保存该选项）
2、保存默认打印机名称
3、设定新的默认打印机
4、取得默认打印机的选项
5、修改属性，如纸张选择，横纵等。6、打印输出
7、还原默认打印设备
// 得到默认打印设备名称
CString strDefualtDev = TEXT("");
PRINTDLG pd;
LPDEVMODE lpDevMode;
if(AfxGetApp()->GetPrinterDeviceDefaults(&pd))
{
lpDevMode=(LPDEVMODE)GlobalLock(pd.hDevMode);
if(lpDevMode)
{ 
strDefualtDev = lpDevMode->dmDeviceName;
}
GlobalUnlock(pd.hDevMode);
}
// 指定的打印机名称
::SetDefaultPrinter("Adobe PDF");  // 在这里我选择的打印机是选定的Adobe虚拟打印机
// 得到刚刚设定的打印机名称
if(AfxGetApp()->GetPrinterDeviceDefaults(&pd))   
{
lpDevMode=(LPDEVMODE)GlobalLock(pd.hDevMode);       
if(lpDevMode)
{ 
lpDevMode->dmPaperSize=DMPAPER_A4;    // 设定打印纸张幅面
lpDevMode->dmOrientation=DMORIENT_LANDSCAPE; // 设定横向打印
lpDevMode->dmPrintQuality=600;     // 设定打印机分辨率
}  
GlobalUnlock(pd.hDevMode);
}
DOCINFO di;
memset( &di, 0, sizeof(DOCINFO) );
di.cbSize = sizeof(DOCINFO); 
di.lpszDocName = "Bitmap Printing Test"; // 设定打印文档名称
di.lpszOutput = (LPTSTR) NULL; 
di.fwType = 0; 
// Begin a print job by calling the StartDoc function. 
int nError;
HDC hdc = ::CreateDC(NULL, "Adobe PDF", NULL, lpDevMode); // 得到打印机设备句柄
if(hdc != NULL)
{
if((nError = StartDoc(hdc, &di)) > 0)
{
if(StartPage(hdc)>0)
{
int xPage = ::GetDeviceCaps(hdc, HORZRES); // 得到可打印纸张的高度
int yPage = ::GetDeviceCaps(hdc, VERTRES); // 得到可打印纸张的宽度
// 在一下地方进行打印输出
if(EndPage(hdc)>0) // 只有结束页成功了才可以关闭文档
EndDoc(hdc); // 关闭打印文档
}
}
}
/// 还原默认的打印设备设定
::SetDefaultPrinter(strDefualtDev); 


/////////////////////////开始调取打印机-operation 001 ////////////////////////////////////

printInfo.hDevNames = 0;
//这个是关键，PD_RETURNDC 如果不设这个标志，就拿不到hDC了
//            PD_RETURNDEFAULT 这个就是得到默认打印机，不需要弹设置对话框
printInfo.Flags = PD_RETURNDC | PD_RETURNDEFAULT;  


PrintDlg(&printInfo);//调用API拿出默认打印机
DWORD rst = CommDlgExtendedError();//看看出错没有
if(rst != 0)
{//出错了，清空标志再次调用API，此时就会弹出打印设置对话框供用户选择了
MessageBox("默认打印机调取失败，请手动选择！");
printInfo.Flags = 0;
PrintDlg(&printInfo);
}

得到了 dc之后就不用我再说了吧，自己搞定就是了，

关于 打印机的一些操作函数和疑问：

根据打印机的名称可以打开打印机，并且获取打印机的名称。
OpenPrinter
The OpenPrinter function retrieves a handle identifying the specified printer or print server. 

BOOL OpenPrinter(
  LPTSTR pPrinterName, // pointer to printer or server name
  LPHANDLE phPrinter,  // pointer to printer or server handle
  LPPRINTER_DEFAULTS pDefault 
                       // pointer to printer defaults structure
);

GetPrinter
The GetPrinter function retrieves information about a specified printer. 
BOOL GetPrinter(
  HANDLE hPrinter,    // handle to printer of interest
  DWORD Level,        // version of printer info data structure
  LPBYTE pPrinter,    // pointer to array of bytes that receives 
                      // printer info structure
  DWORD cbBuf,        // size, in bytes, of the pPrinter buffer
  LPDWORD pcbNeeded   // pointer to variable with count of bytes 
                      // retrieved (or required)
);

但是操作过上面的两个函数后该怎么使用打印机呢？

关闭打印机
ClosePrinter
The ClosePrinter function closes the specified printer object. 

BOOL ClosePrinter(
  HANDLE hPrinter   // handle to printer object
);
