c++在程序中使用Adobe Acrobat SDK将pdf文件发送到打印机进行打印

以下是在程序中使用Adobe Acrobat SDK将pdf文件发送到打印机进行打印的示例代码：

#include "stdafx.h"
#include "Acrodist.h"

void PrintPDF(const CString& filePath)
{
    // Initialize Acrobat SDK
    CoInitialize(NULL);
    CAcroDistiller* pDistiller = NULL;
    HRESULT hr = CoCreateInstance(__uuidof(AcroDistiller), NULL, CLSCTX_INPROC_SERVER, __uuidof(CAcroDistiller), (void**)&pDistiller);
    if (FAILED(hr))
    {
        MessageBox(NULL, _T("Failed to initialize Acrobat SDK."), _T("Error"), MB_OK | MB_ICONERROR);
        return;
    }

    // Set the job options
    VARIANT varJobOptions;
    VariantInit(&varJobOptions);
    varJobOptions.vt = VT_BSTR;
    varJobOptions.bstrVal = SysAllocString(L"DefaultJobOptions");

    // Create the job options object
    IDispatch* pJobOptions = NULL;
    hr = pDistiller->CreateJobOptions(&pJobOptions);
    if (FAILED(hr))
    {
        MessageBox(NULL, _T("Failed to create job options object."), _T("Error"), MB_OK | MB_ICONERROR);
        pDistiller->Release();
        return;
    }

    // Set the job options object
    hr = pDistiller->SetJobOptions(varJobOptions, pJobOptions);
    if (FAILED(hr))
    {
        MessageBox(NULL, _T("Failed to set job options object."), _T("Error"), MB_OK | MB_ICONERROR);
        pJobOptions->Release();
        pDistiller->Release();
        return;
    }

    // Create the job
    IDispatch* pJob = NULL;
    hr = pDistiller->CreateJob(filePath.AllocSysString(), NULL, NULL, &pJob);
    if (FAILED(hr))
    {
        MessageBox(NULL, _T("Failed to create job."), _T("Error"), MB_OK | MB_ICONERROR);
        pJobOptions->Release();
        pDistiller->Release();
        return;
    }

    // Set the job options for the job
    hr = pJob->SetJobOption(_T("Print"), _T("True"));
    if (FAILED(hr))
    {
        MessageBox(NULL, _T("Failed to set job option for printing."), _T("Error"), MB_OK | MB_ICONERROR);
        pJob->Release();
        pJobOptions->Release();
        pDistiller->Release();
        return;
    }

    // Start the job
    hr = pJob->Start();
    if (FAILED(hr))
    {
        MessageBox(NULL, _T("Failed to start job."), _T("Error"), MB_OK | MB_ICONERROR);
        pJob->Release();
        pJobOptions->Release();
        pDistiller->Release();
        return;
    }

    // Wait for the job to complete
    VARIANT varComplete;
    VariantInit(&varComplete);
    varComplete.vt = VT_BOOL;
    varComplete.boolVal = VARIANT_FALSE;
    while (varComplete.boolVal == VARIANT_FALSE)
    {
        hr = pJob->GetJobOption(_T("Complete"), &varComplete);
        if (FAILED(hr))
        {
            MessageBox(NULL, _T("Failed to get job option for completion."), _T("Error"), MB_OK | MB_ICONERROR);
            pJob->Release();
            pJobOptions->Release();
            pDistiller->Release();
            return;
        }
    }

    // Release the job and job options objects
    pJob->Release();
    pJobOptions->Release();

    // Release the distiller object
    pDistiller->Release();

    // Uninitialize Acrobat SDK
    CoUninitialize();
}

该函数接受一个文件路径参数，并使用该路径创建一个Acrobat Distiller作业。然后，它设置打印作业选项，并将作业设置为打印。最后，它启动作业并等待作业完成。如果作业成功完成，则PDF文件将被发送到默认打印机进行打印。如果出现任何错误，则会显示一个错误消息框。
