请问下各位大佬arx中怎么打印图纸的啊,网上没找到资料；

LoveArx

下面是ARX中用ACTIVEX批处理打印所有LAYOUTS的简单例子代码

关键步骤是：

1) Set the number of layouts be plotted using the method StartBatchMode() of the IAcadPlot object.

2) Preparing a variant array of BSTRs having the names of the layouts to be plotted and then pass it as argument to SetLayoutsToPlot() method.

3) Finally to plot, use PlotToDevice() method.

1. //use MFC to test this code
   
2. #import "acax19enu.tlb" raw_interfaces_only no_namespace
   
3. void fBatchPlotLayouts()
   
4. {
   
5. try
   
6. {
   
7.   //get the AutoCAD application
   
8.   IAcadApplicationPtr pApp = NULL;
   
9.   pApp = acedGetAcadWinApp()->GetIDispatch(TRUE);
   
10.   //get the Active Document
    
11.   IAcadDocumentPtr pDoc = NULL;
    
12.   pApp->get_ActiveDocument(&pDoc);
    
13.   IAcadLayoutsPtr pLayOuts;
    
14.   IAcadLayoutPtr pLayOut;
    
15.   long mNumberOflayouts;
    
16.   //get the layouts collection and the number of layouts
    
17.   pDoc->get_Layouts(&pLayOuts);
    
18.   pLayOuts->get_Count(&mNumberOflayouts);
    
19.   //create the variant array that will hold the layout names
    
20.   VARIANT mLayArr;
    
21.   SAFEARRAYBOUND mSAB;
    
22.   mSAB.lLbound = 0;
    
23.   mSAB.cElements = mNumberOflayouts;
    
24.   VariantInit(&mLayArr);
    
25.   mLayArr.vt = VT_ARRAY | VT_BSTR;
    
26.   mLayArr.parray = SafeArrayCreate(VT_BSTR,1,&mSAB);
    
27.   //populate the variant array
    
28.   long mCtr;
    
29.   //note that array here has zero based index
    
30.   for(mCtr = 0; mCtr < mNumberOflayouts; mCtr ++)
    
31.   {
    
32.    pLayOuts->Item(_variant_t(mCtr), &pLayOut);
    
33.    BSTR strName;
    
34.    pLayOut->get_Name(&strName);
    
35.    SafeArrayPutElement(mLayArr.parray, &mCtr, strName);
    
36.   }
    
37.   //print the layout names that are being plotted
    
38.   BSTR bstrName;
    
39.   acutPrintf(_T("\nLayouts to be plotted:"));
    
40.   for(mCtr = 0; mCtr < mNumberOflayouts;mCtr ++)
    
41.   {
    
42.    SafeArrayGetElement(mLayArr.parray,&mCtr,&bstrName);
    
43.    acutPrintf(_T("\n%s"),(TCHAR*)(_bstr_t)bstrName);
    
44.   }
    
45.   acutPrintf(_T("\nPlotting started...\n"));
    
46.   //plot the layouts
    
47.   IAcadPlotPtr pPlot;
    
48.   pDoc->get_Plot(&pPlot);
    
49.   //set the number of plots and error mode to quiet
    
50.   pPlot->put_NumberOfCopies(1);
    
51.   pPlot->put_QuietErrorMode(VARIANT_TRUE);
    
52.   //number of layouts to be plotted
    
53.   pPlot->StartBatchMode(mNumberOflayouts);
    
54.   //set the layouts to plot
    
55.   pPlot->SetLayoutsToPlot(mLayArr);
    
56.   VARIANT_BOOL returnBool;
    
57.   pPlot->PlotToDevice(_variant_t("DWF6 ePlot.pc3"), &returnBool);
    
58.   //clean up
    
59.   VariantClear(&mLayArr);
    
60. }
    
61. catch (_com_error &e)
    
62. {
    
63.   acutPrintf(
    
64.    _T("\nError while batch plotting. %s"),e.ErrorMessage());
