获取打印机状态，判断打印机状态，获取打印机驱动信息获取打印机状态，判断打印机状态，获取打印机驱动信息：driver_info_8 获取打印机状态可以使用getprinter。 BOOL GetJobs() { DWORD dwNeeded = 0; PRINTER_INFO_2 * pPrinterInfo = (PRINTER_INFO_2 *)malloc(0); HANDLE m_hPrinter = NULL; wchar_t ... 阅读详情

在一个对话框中，当点击打印按钮之后，弹出标准打印对话框，然后进行打印，主要代码如下：
void CMyDialog::OnBnClickPrint()
{
CDC pDc;
CPrintDialog dlg(FALSE); //标准打印对话框
if( IDOK == dlg.DoModal() )
{
pDc.Attrack(dlg.GetPrintDC());
}
pDc.Textout(100,100,"Hellow World!");
pDc.DeleteDc();
}
怎样判断打印机的一些状态（例如：打印机没开、缺纸等），然后给用户一些提示？
刚刚接触打印这一块，希望大家帮帮我，谢谢了！！

发送ZPL指令到斑马打印机，并监控打印成功或者失败的状态信息本文共分为两个部分：第一部分：介绍如何与Zebar进行连接，把ZPL指令或者模板文件发送到斑马打印机进行打印。第二部分：介绍如何接收Zebar进行打印之后如何得到斑马打印机的反馈信息，防止打印出错的情况下继续进行工业的操作。需要用上位机得到打印出错的信息，然后反馈给PLC。一、C# 将指令发送到Zebar打印机的方式发送ZPL到打印机的参考链接 Zebra Technologies (GitHub Demo) C#控制打印的Demo 1、利用winspool打印机库函数(LPT,US. 阅读详情

GetPrinter
The GetPrinter function retrieves information about a specified printer.

BOOL GetPrinter(
HANDLE hPrinter, // handle to printer
DWORD Level, // information level
LPBYTE pPrinter, // printer information buffer
DWORD cbBuf, // size of buffer
LPDWORD pcbNeeded // bytes received or required
);
Parameters
hPrinter
[in] Handle to the printer for which the function retrieves information. Use the OpenPrinter or AddPrinter function to retrieve a printer handle.
Level
[in] Specifies the level or type of structure that the function stores into the buffer pointed to by pPrinter.
Windows 95/98/Me: This value can be 1, 2, or 5.

Windows NT/2000/XP: This value can be 1, 2, 3, 4, 5, 6, 7, 8 or 9.

pPrinter
[out] Pointer to a buffer that receives a structure containing information about the specified printer. The buffer must be large enough to receive the structure and any strings or other data to which the structure members point. If the buffer is too small, the pcbNeeded parameter returns the required buffer size.
The type of structure is determined by the value of Level. Level Structure
1 A PRINTER_INFO_1 structure containing general printer information.
2 A PRINTER_INFO_2 structure containing detailed information about the printer.
3 Windows NT/2000/XP: A PRINTER_INFO_3 structure containing the printer's security information.
4 Windows NT/2000/XP: A PRINTER_INFO_4 structure containing minimal printer information, including the name of the printer, the name of the server, and whether the printer is remote or local.
5 A PRINTER_INFO_5 structure containing printer information such as printer attributes and time-out settings.
6 Windows 2000/XP: A PRINTER_INFO_6 structure specifying the status value of a printer.
7 Windows 2000/XP: A PRINTER_INFO_7 structure that indicates whether the printer is published in the directory service.
8 Windows 2000/XP: A PRINTER_INFO_8 structure specifying the global default printer settings.
9 Windows 2000/XP: A PRINTER_INFO_9 structure specifying the per-user default printer settings.

cbBuf
[in] Specifies the size, in bytes, of the buffer pointed to by pPrinter.
pcbNeeded
[out] Pointer to a variable that the function sets to the size, in bytes, of the printer information. If cbBuf is smaller than this value, GetPrinter fails, and the value represents the required buffer size. If cbBuf is equal to or greater than this value, GetPrinter succeeds, and the value represents the number of bytes stored in the buffer.
Return Values
If the function succeeds, the return value is a nonzero value.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

有人写的然后编写获取打印机状态的函数如下:

/// <summary>
/// 获取打印机的当前状态
/// </summary>
/// <param name="PrinterDevice">打印机设备名称</param>
/// <returns>打印机状态</returns>
private PrinterStatus GetPrinterStat(string PrinterDevice)
{
PrinterStatus ret=0;
string path=@"win32_printer.DeviceId='"+PrinterDevice+"'";
ManagementObject printer=new ManagementObject(path);
printer.Get();
ret=(PrinterStatus)Convert.ToInt32(printer.Properties["PrinterStatus"].Value);
return ret;
}

调用示例:

MessageBox.Show(GetPrinterStat("\\\\192.168.0.88\\Samsung SCX-4x16 Series").ToString());

Trackback: http://tb.blog.csdn.net/TrackBack.aspx?PostId=352678

补充:System.Windows.Forms.MessageBox.Show(printer.Properties["WorkOffline"].Value.ToString());

可以获取打印机是否离线.
没测试过
