Question

打印机调用哪几个api函数来打印数据

Answer 1

在MSDN库中去找。取一个函数名拷贝到MSDN的关键字栏里搜索就出来了，而且有详细的参数解释及用法。如：EndPagePrinter

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

Parameters

hPrinter
[in] Handle to the printer for which the page will be concluded. Use the OpenPrinter or AddPrinter function to retrieve a printer
handle.

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.

Remarks

Each page in a print job begins with a StartPagePrinter function call and ends with
an EndPagePrinter function call. The data for each page is written to the
print file by using the WritePrinter
function.

Requirements

Windows NT/2000: Requires Windows NT 3.1 or later.
Windows
95/98: Requires Windows 95 or later.
Header: Declared in
Winspool.h; include Windows.h.
Library: Use Winspool.lib.
