C# Imprimir Word Tutorial: Guía Paso a Paso

Create a New Console Application

1. Open Visual Studio.
2. Click on "Create a new project."
3. Search for "Console App" and select the appropriate C# template.
4. Name your project (e.g., "InteropPrintConsoleTutorial") and choose a suitable location.

Adding Interop Reference

Using Interop requires a reference to the Microsoft Office Interop library. Here's how to add it:

1. In Visual Studio, right-click on your Console project in the Solution Explorer.
2. Navigate to Add > Reference.
3. In the Reference Manager window, go to the COM tab.
4. Type "Microsoft Word" in the search bar to filter the list.
5. From the results, select "Microsoft Word xx.x Object Library" (where xx.x denotes the version number).
6. Click on the OK button to add the reference.

You can also install it using the NuGet Package Manager.

Verify Application Settings

Ensure that your application's target framework is compatible with the Interop library. You can check this by right-clicking on your project in Solution Explorer, selecting Properties, and then viewing the Target framework under the Application tab. If you face issues with the Interop library's version, consider downloading the necessary package or assembly or adjusting the target framework version.

With the environment set up, you can now proceed with the coding process.

Basic Printing of Word Document

To print the document, you can use the following method:

// Method to print the document using default printer settings
private void ButtonPrint_Click(object sender, EventArgs e)
{
    wordDoc.PrintOut(); // Sends the document to the default printer
}

// Method to print the document using default printer settings
private void ButtonPrint_Click(object sender, EventArgs e)
{
    wordDoc.PrintOut(); // Sends the document to the default printer
}

' Method to print the document using default printer settings
Private Sub ButtonPrint_Click(ByVal sender As Object, ByVal e As EventArgs)
	wordDoc.PrintOut() ' Sends the document to the default printer
End Sub

This method sends the document to the default printer using the default settings.

Print Word Documents with Customizations

If you want to introduce a print dialog, customize printer settings, or even print multiple pages, you'd require a more detailed approach:

// Method to print the document with custom settings
private void ButtonPrintWithSettings_Click(object sender, EventArgs e)
{
    // Number of copies to print
    object copies = "1";

    // Page range to print, e.g., pages 1 to 3
    object pages = "1-3";

    // Print the document with specified copies and page range
    wordDoc.PrintOut(Copies: ref copies, Pages: ref pages);
}

// Method to print the document with custom settings
private void ButtonPrintWithSettings_Click(object sender, EventArgs e)
{
    // Number of copies to print
    object copies = "1";

    // Page range to print, e.g., pages 1 to 3
    object pages = "1-3";

    // Print the document with specified copies and page range
    wordDoc.PrintOut(Copies: ref copies, Pages: ref pages);
}

' Method to print the document with custom settings
Private Sub ButtonPrintWithSettings_Click(ByVal sender As Object, ByVal e As EventArgs)
	' Number of copies to print
	Dim copies As Object = "1"

	' Page range to print, e.g., pages 1 to 3
	Dim pages As Object = "1-3"

	' Print the document with specified copies and page range
	wordDoc.PrintOut(Copies:= copies, Pages:= pages)
End Sub

In the above source code, we specify the page range and number of copies, but the potential customizations are vast.

Silent Printing

Silent printing is all about sending the document to the printer without any user interactions:

// Object to determine whether to print in the background or not
object background = false;

// Print the document silently (no user interactions)
wordDoc.PrintOut(Background: ref background);

// Object to determine whether to print in the background or not
object background = false;

// Print the document silently (no user interactions)
wordDoc.PrintOut(Background: ref background);

' Object to determine whether to print in the background or not
Dim background As Object = False

' Print the document silently (no user interactions)
wordDoc.PrintOut(Background:= background)

Specifying a Printer

To print a document on a specific printer other than the default:

// Set the active printer to a specified printer by name
wordApp.ActivePrinter = "Printer Name";

// Print the document using the specified printer
wordDoc.PrintOut();

// Set the active printer to a specified printer by name
wordApp.ActivePrinter = "Printer Name";

// Print the document using the specified printer
wordDoc.PrintOut();

' Set the active printer to a specified printer by name
wordApp.ActivePrinter = "Printer Name"

' Print the document using the specified printer
wordDoc.PrintOut()

Advanced Printer Settings

Beyond just specifying the printer, one might need to adjust the printer settings:

// Creates a PrintDialog to allow the user to choose printer settings
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == DialogResult.OK)
{
    // Sets the Word application's active printer to the user's choice
    wordApp.ActivePrinter = printDialog.PrinterSettings.PrinterName;

    // Prints the document using user's selected printer settings
    wordDoc.PrintOut();
}

// Creates a PrintDialog to allow the user to choose printer settings
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == DialogResult.OK)
{
    // Sets the Word application's active printer to the user's choice
    wordApp.ActivePrinter = printDialog.PrinterSettings.PrinterName;

    // Prints the document using user's selected printer settings
    wordDoc.PrintOut();
}

' Creates a PrintDialog to allow the user to choose printer settings
Dim printDialog As New PrintDialog()
If printDialog.ShowDialog() = DialogResult.OK Then
	' Sets the Word application's active printer to the user's choice
	wordApp.ActivePrinter = printDialog.PrinterSettings.PrinterName

	' Prints the document using user's selected printer settings
	wordDoc.PrintOut()
End If

This way, the user can manually adjust settings like orientation, duplex printing, and more.
