POS电脑小票直接打印到LPT1的错误捕捉

zyp

谢谢tmtony 站长

我测试了一下,
StartDocPrinter Lib "winspool.drv" Alias _
      "StartDocPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, _
      pDocInfo As DOCINFO) As Long

代码中那个hPrinter参数为要进行打印的打印机(指定一个已打开的打印机的句柄), baidu一下好像需要用到:
Private Declare Function OpenPrinter Lib "winspool.drv" Alias _
      "OpenPrinterA" (ByVal pPrinterName As String, phPrinter As Long, _
      ByVal pDefault As Long) As Long
来取得, 这对于不安装驱动程序而是直接输出到LPT1并口的不知如何取得lhPrinter
另外,对于pDocInfo这个参数的使用也不得要领;

继续测试和找资料中

谢谢大家的关注
