C# Print Word Documents with Physical Printer

Provided through the free .NET libraryPrintDocument Class, we can print Word documents on the specified printer, and we can also specify settings printing options, such as the page range, number of copies, and paper size to be printed.

C# code:

using ;
using ;
 
namespace PrintWordDocument
{
    class Program
    {
        static void Main(string[] args)
        {
            //Load Word Documents
            Document doc = new Document();
            ("Example.docx");
 
            //Get PrintDocument object
            PrintDocument printDoc = ;
 
            //Specify the printer name
             = "Printer name";
 
            //Specify the range of pages to print
             = 1;
             = 10;
 
            //Set the number of copies printed
             = 1;
 
            //Specify the paper size
             = new PaperSize("custom", 500, 800);
 
            //Print a document
            ();
        }
    }
}

 

C# silently print Word documents

Silent printing means that the printing operation is automatically completed through the program or system settings during the printing process without popping up the printing dialog box. Using Free we can PrintControllerThe property is set toStandardPrintController, used to hide the printing process, thereby realizing silent printing.

C# code:

using ;
using ;
 
namespace SilentlyPrintWord
{
    class Program
    {
        static void Main(string[] args)
        {
            //Load Word Documents
            Document doc = new Document();
            ("Example.docx");
 
            //Get PrintDocument object
            PrintDocument printDoc = ;
 
            //Specify the printer name
             = "Printer name";
 
            //Set PrintController property to StandardPrintController to hide the print process
             = new StandardPrintController();
 
            //Print a document
            ();
        }
    }
}

 

Notice:The printing effect and parameter settings cannot be confirmed in real time when printing silently. If the printer fails or the printing parameter settings are incorrect, it may cause the printing to fail or the results to not meet expectations. Therefore, before officially using silent printing, it is recommended to conduct tests to ensure that the printing settings and printer status are normal.

 

C# Convert Word to PDF via Virtual Printer

A virtual printer is a kind of software that can simulate and implement the functions of the printer, but does not involve actual paper and ink consumption, but converts electronic documents into electronic files in a specific format to save them on a computer. In addition to physical printers, Free also supports the use of virtual printers.

C# code:

using ;
using ;
 
namespace PrintWordToPdf
{
    class Program
    {
        static void Main(string[] args)
        {
            //Load Word Documents
            Document doc = new Document();
            ("Example.docx");
 
            //Get PrintDocument object
            PrintDocument printDoc = ;
 
            //Print output to file
             = true;
 
            //Specify the virtual printer name
             = "Microsoft Print to PDF";
 
            //Specify the output file path and name
             = @"C:\Users\Administrator\Desktop\";
 
            //Print a document
            ();
        }
    }
}

 

C# Print multiple pages on one piece of paper

Print multiple related Word document pages on one piece of paper to facilitate comparison viewing and organizing information, improve work efficiency, and reduce paper waste. By usingPrintMultipageToOneSheet()The method can implement this operation.

C# code:

using ;
using ;
using ;
 
namespace PrintMultiplePagesOnOneSheet
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Load Word Documents
            Document doc = new Document();
            ("Example.docx");
 
            //Get PrintDocument object
            PrintDocument printDoc = ;
 
            //Enable single-sided printing
             = ;
 
            //Print the specified number of pages to one page
            (, false);
        }
    }
}
