并口打印机问题!

用CreateFile打印并口打印，用WriteFile来打印，请教怎么取得打印机状态和复位打印机呢?有没有直接API可以完成的，比如使用文件IO控制函数?

清除错误状态命令
就是这个东西，偶要了，但是命令也要用writefile写下去了，不然怎么控制呢

你找EPSON要一份命令手册就可以了。
出错后不是WriteFile不能写，是要先发一个清除错误状态命令然后打印机才会响应

直接对口操作的偶会,不过觉得既然有系统的函数，就想用系统函数

我觉得还是使用 IO 控制比较简单了，这个资料搜索一下就有了
一般 LPT1 = 0x378

但是如果打印机出错之后，或者缺纸之后WriteFile就不能写东西了啊，怎么做复位操作呢?
偶用的EPSON的BAT500,你用的什么啊?

参考直接访问和控制电脑的打印口(并行口)
for Windows 98/ME/NT/2000/XP/2003

用winIO包可以解决

BCB提供了TPrinter操作打印机。
Retrieves information about the current printer.

void __fastcall GetPrinter(char * ADevice, char * ADriver, char * APort, int &ADeviceMode);

Description

Call GetPrinter to obtain information about the current printer.

ADevice is a buffer that receives the device name of the current printer. This is the name that appears in the Print Manager (for example, "Epson FX-80"). It is not the printer model name.

ADriver is a buffer that receives the driver name for the current printer. Some versions of Windows do not use printer driver names, in which case this buffer is unused. On versions of Windows that support printer driver names, this is the name of a printer driver (usually 慦INSPOOL?.

APort is a buffer that receives the port used by the current printer. It is not used on 32-bit versions of Windows, but is included for backward compatibility.

DeviceMode returns the handle to a memory buffer containing a DEVMODE structure, which contains device-specific initialization data for the device driver. Use the GlobalLock function to convert this handle into a pointer to the structure.
