您好在中创建一个通用文本打印机pc（添加新打印机......或谷歌如何添加通用文本打印机）



看看这篇文章如何将原始数据发送到打印机。



http://support.microsoft.com/kb/322090 [ ^ ]



使用它你可以将ESC / POS命令发送到打印机。



对于ESC / POS命令参考使用此链接 http://www.google.co.in/url?sa=t&source=web&cd=1&ved=0CBYQFjAA&url=http%3A%2F%2Fnicholas.piasecki.name ％2Fblog％2Fwp-content％2Fuploads％2F2009％2F12％2FESC-POS-Command-Guide.pdf& ei = kaxbTcvZI8uXcde_iNoK& usg = AFQjCNFX385l9jOit_86cfsoHmpH4kPKKQ [ ^ ]

1.使用打印机端口创建打印机的句柄

2.WriteFile（句柄，Str，len，0，NULL）

  public   partial   class  frmBook：表格
 {
 
 
 
  public   const   Int32  FILE_ATTRIBUTE_NORMAL =  128 ;  //  初始化端口属性 
  public   const   Int32  INVALID_HANDLE_VALUE = -1;

  public   const   Int32  GENERIC_WRITE =  1073741824 ; 
  public   const   Int32  CREATE_NEW =  1 ; 
  public   const   Int32  CREATE_ALWAYS =  2 ; 
  public   const   Int32  OPEN_EXISTING =  3 ; 
 
 
 
 
 受保护  void  Print_Ticket（ string  ticketNo， string  seatNo， string  Showtime， string 价格）
 {
 
  IntPtr  ptr = CreateFile（  LPT1，GENERIC_WRITE， 0 ，
  IntPtr  .Zero，OPEN_EXISTING，FILE_ATTRIBUTE_NORMAL， IntPtr  .Zero）; 
 
  / *  处理不好？ INVALID_HANDLE_VALUE * /  
  if （ptr.ToInt32（）== -1）
 {
  / *  要求框架将win32错误代码编组为异常* /

Hi,

I want to print the receipt to thermal printer without using OPOS driver.

Please guide me in this case.

Thanks

Hi Create a Generic text printer in the pc (Add new Printer...or google it how to add a generic text printer)

Look at this article how to send raw data to printer.

http://support.microsoft.com/kb/322090[^]

using this you can send ESC/POS commands to the printer.

For ESC/POS commands reference use this link http://www.google.co.in/url?sa=t&source=web&cd=1&ved=0CBYQFjAA&url=http%3A%2F%2Fnicholas.piasecki.name%2Fblog%2Fwp-content%2Fuploads%2F2009%2F12%2FESC-POS-Command-Guide.pdf&ei=kaxbTcvZI8uXcde_iNoK&usg=AFQjCNFX385l9jOit_86cfsoHmpH4kPKKQ[^]
