Simple Wrapper for Printing Text in .net

tinstaafl 1 577 Views

Here's a simple wrapper for printing text. Built as a class library, this can be used in any .net application. This has automatic word wrapping. I figured that using the new constructor to accept different parameters would easily allow for printing different documents with different settings. I included Name, Font, and Landscape, but the structure is quite simple and can easily be adapted to include or exclude any property or setting.

Usage is quite simple, build a string using linebreaks if needed(C#-'\n', VB-vbNewLine), declare a new PrintDoc, then call the Print() method.

//C#
PrintDoc pd = new PrintDoc(MyString);
pd.Print();

'VB
Dim pd as New PrintDoc(MyString)
pd.Print()

Options include adding a Document name to the top of the printout, using a different font, or using Landscape orientation. The options are included as overloads, Landscape is optional in each overload, when declaring the new PrintDoc.

Hope someone can find this useful.
