PrintForm Component

The PrintForm component is a non-visual tool in the Visual Basic PowerPacks library that allows you to easily print a snapshot of a Windows Forms application (or UserControl) without having to write complex, code-heavy printing routines. It captures the form exactly as it appears on the screen, including text, graphics, and visual controls.

Because the PowerPacks are legacy components, this tool is typically used in maintaining or upgrading older .NET Framework Windows Forms applications (e.g., .NET 2.0 to 4.8). Core Features

Output Flexibility: You can send the output directly to a default or selected printer (PrintToPrinter), view it in a Windows Forms Print Preview window (PrintToPreview), or save it as a PostScript file (PrintToFile).

Control Over Printed Areas: You can choose to print only the client area (just the controls, no title bar or borders), the full window (client area + title bar, scroll bars, and borders), or the entire scrollable form regardless of what is currently on the screen. Key Properties & Methods

PrintAction: An enumeration that sets the destination of the output. The valid values are PrintToPrinter, PrintToPreview, and PrintToFile.

Form: Specifies the exact Windows Form you want to print. If you drag the component from the toolbox onto the form during design time, this property defaults to the form it was placed on.

Print() Method: The primary action method. It has both a parameterless version (Print()) and an overloaded version that accepts printing options (Print(Form, PrintOption)).

PrintFileName: When PrintAction is set to PrintToFile, this property defines the full path and filename for saving an Encapsulated PostScript (EPS or PS) file.

PrinterSettings: Allows you to access the underlying .NET printing architecture if you need to programmatically define margins, specific printer trays, or the number of copies. How to use it in Code

To use the component, you first drag PrintForm onto your Windows Form from the Visual Basic PowerPacks tab in the toolbox. It will appear in the tray at the bottom of the designer window.

To trigger a print preview, you would use code similar to this in a Button click event:

’ Send output to the Print Preview dialog PrintForm1.PrintAction = Printing.PrintAction.PrintToPreview ‘ Trigger the Print method, printing the entire window including borders PrintForm1.Print(Me, Microsoft.VisualBasic.PowerPacks.Printing.PrintForm.PrintOption.FullWindow) Use code with caution. Limitations to keep in mind

Resolution Quality: Because it prints a rendered visual “image” of the screen (akin to a screenshot), the printout may look grainy or low-resolution compared to native text and vector documents.

Graphics Rendering Issues: On certain operating systems, graphics or text drawn programmatically via System.Drawing.Graphics might not render correctly when utilizing the overloaded print options. If you encounter artifacts, try using the standard basic Print() method, or call the form’s Refresh() method right before calling .Print().

Legacy Dependency: The Visual Basic PowerPacks were officially retired by Microsoft. While they can still be downloaded and referenced in modern versions of Visual Studio (targeting the older .NET Framework), they do not come pre-installed in modern .NET Core / .NET 5+ environments.

If you are trying to build more robust or high-resolution reports in your application, you might find it better to utilize the native PrintDocument component or a third-party reporting tool like Crystal Reports or Stimulsoft. If you are using this in an ongoing project, let me know: Is this for a new or existing application?

What kind of destination are you targeting (a physical printer, preview, or file)?
