Changing Document Name in Printer Spooler when Printing Postscript file generated by Ghostscript using C#
When working with Postscript files generated by Ghostscript, you may need to change the document name that appears in the printer spooler when printing the file. This is particularly useful when you have multiple Postscript files that need to be printed in a specific order. In this article, we will cover the key concepts of how to change the document name using C#.
Understanding the Printing Process
Before we dive into the code, it's important to understand the printing process. When you print a document, the print spooler takes the document and sends it to the printer. The document name that appears in the print spooler is typically the name of the file you are printing. However, you can change this name programmatically using C#.
Setting up the Printing System
To change the document name, you first need to set up the printing system. This includes creating a PrintDocument object and specifying the printer to be used. Here's an example:
PrintDocument printDoc = new PrintDocument();
printDoc.PrinterSettings.PrinterName = "My Printer";
Changing the Document Name
Once the printing system is set up, you can change the document name by setting the PrintDocument.DocumentName property. Here's an example:
printDoc.DocumentName = "My Custom Document Name";
Printing the Postscript File
Now that the document name has been changed, you can print the Postscript file. To do this, you first need to load the Postscript file into a Stream object. Then, you can use the PrintDocument.PrintPage event to print the file. Here's an example:
Stream psStream = new FileStream("myfile.ps", FileMode.Open);
printDoc.PrintPage += (sender, e) =>
{
e.Graphics.DrawStream(psStream);
};
printDoc.Print();
- Setting up the printing system involves creating a
PrintDocumentobject and specifying the printer to be used. - Changing the document name can be done by setting the
PrintDocument.DocumentNameproperty. - Printing the Postscript file involves loading the file into a
Streamobject and using thePrintDocument.PrintPageevent to print the file.
