Believe me, it is easy. As with any class, before we can use any of the Classes, Events and Objects available to us in the .Net Framework we need to import the Namespaces we need. For this we need 3 namespaces. VB.Net users only required 2 because VB.Net assumes the System Namespace, whereas C# isn't so kind:
- PRN file is a Printer Text file. The PRN is the file created using the 'print to file' option. The PRN file contains the same bytes of data that would have been sent to the selected printer had you not chosen to print to a file. This file can be printed on any printer of the same type for.
- The various departments each use a separate printer. In this situation, an invoicing application can create, with each invoice, a text file containing both data and a Print Command Script, with the script instructing BarTender to: Open the specified BarTender document. Use the trigger file as the data file. Print to a specific printer.
- System
- System.Drawing
- System.Drawing.Printing
Print.prn File
Printing.prn files in win9x, part 1 If you use software that creates.prn files for printing later (e.g., as part of a batch job), it's useful to know how to print them manually. Check the box for Print to file. Navigate to the location where you want to save the print file, and give the file a descriptive name: Click OK to create the printer file. Even if this file has the file extension prn, it will be a postscript file and should be able to be opened in GSView. The code deals with taking pre-generated PRN files and sending these to a printer. However I'm a little confused as to how to do this using C#. I've looked at PrintDocument, but I don't think that's doing what I want to do as I intend to send the PRN file straight to the printer (in some cases I need to modify the data before it gets sent to.
These 3 Namespaces contain everything we need for this class, so you will need to add the following lines to the top of your class file:
Now we have to inherit the PrintDocument Class. To do this, make the following change to the declaration of your class:
So now we have a shell to work with that inherits from the PrintDocument Class, so lets add some functionality and other code to our class. In our class we will have 2 properties, one to hold the text that we are printing, and one to hold the Font we will be using when printing our document. We will also add a variable to hold the current character we are working with. This is necessary for more than one page texts.
Adding the Font property allows us to override the default font.
Next we will incorporate some Constructors for our class. Since we are inheriting from a separate class, we need to call the Constructor of the base class. This is done by using base(), this will call the Constructor of our base class, the PrintDocument Class:
Now we have our Properties and our Constructors, next we will add a couple methods to our class. In our printing class we will be overriding 2 of the PrintDocument methods, those will be the OnBeginPrint method and the OnPrintPage method. In the OnBeginPrint method we will override the default font with the font we specify, and in the OnPrintPage we will be setting up the specifics of our page. We will be setting the following properties:
- Page Size
- Page Orientation (Landscape, Portrait)
- Top Margin
- Left Margin
First, the OnBeginPrint method, as with our Constructors we will need to call our base class's OnBeginPrint method, then we can do our custom work:
As you can see, here we call the base class's OnBeginPrint method, then we check to see if a font was provided, if no one was, we default to Times New Roman. The OnPrintPage method is quite a bit larger and complex, this is where we will be doing the bulk of our work.
In this method we will be setting the size of the print area (the page size), we will determine if the user selected Landscape or Portrait as the print style, we will determine how many lines we are printing and how many lines will fit in our page size, and finally we will tell the printer whether we have more pages to print. As with our OnBeginPrint method, we will need to call our base class's OnPrintPage method before doing our customizing of the method. Let's take a look at our overridden OnPrintPage method:
You will notice that in this method we reference a function called RemoveZeros. This is the last function in our class, and it has an important role. 33 hz benefits. We will create a function that will check our value, and if it's a 0 (not the number, but a memory space with a value of zero – ascii 0 -) we will replace it with a 1 (ascii 1). Zero's can cause bad things to happen when it comes to printing and determining page size and margins, so to alleviate that we use our RemoveZeros Function:
And there you have it, our completed printing class. Now I know some are asking 'I see this class, but how do I use it?'. Well I'm glad you asked, this class is very easy to use. In your Form's code add a procedure named printDocument. Then inside that procedure create an instance of the printer class. Set its properties (PrinterFont, TextToPrint) and then issue a print command, like this:
Some other functions and classes you may find useful are DrawRectangle, FillRectangle, Arc, Brushes and Pen. All these basic functions will help you get beautiful reports if you have the patience to put them together.

How To Open .prn File
Question: I'm trying the evaluation version of VeryPDFPCL Converterand I can't seem to figure out how to convert my prn to PDF file. If I could get this to work I would definitely be interested in purchasing a developers license or SDK that I could use to convert these prn files I receive to pdf. I'm on a limited time frame so I'm trying many different products find a solution to my problem. The first company that can provide me with an answer that fits will get my business. Thank you very much for you time and I hope to hear back from you soon.

Answer: According to your needs, you choose the right software: PCL Converter which can be used to convert PCL, PXL PRN and other printing file formats files to PDF fast and accurately. And for this software, there is also developer version and SDK version, which allows you to call it together with the C#. In the following part, I will give some examples.
Step 1. Download PCL Converter SDK Version How to mswlogo for mac windows 7.
- For uploading and downloading easily, we have compressed it to zip file. Once downloading finishes, please extract it to some folder and check the elements in it.
- When you open it, there are many elements. But it is not hard to find the folder of example_C#_1 and example_C#_2. Open them then you can check the code and example in it.
Step 2. Run the conversion from C#

- The following is the sample of C# from the extracted folder, please have a check.
#include

#include
__declspec(dllexport)
int WINAPI VeryPDFPCLConverter(const char *lpCmd);
void main(int argc, char *argv[])
{
if(argc < 3)
return;
char szCmd[2048] = {0};
for (int i = 1; i < argc; i++)
{
strcat(szCmd, '')
strcat(szCmd, argv[i]);
strcat(szCmd, ' ');
}
printf('%sn', szCmd);
VeryPDFPCLConverter(szCmd);
}
If you need to know more, please check them in the download package. And there are more examples for VB and others.
For checking the result more easily, here I will try to convert PRN to PDF by GUI version. This software either can be use as command line software and GUI version software. The following snapshot is from the output PDF file converted from PRN.
PCL Converter SDK was professionally designed to assist developers, the software programmers, to quickly add a PCL, PRN conversion utility to your own applications. And under the SDK version, you can integrate our product with your application and distribute it with your own application royalty free. This version is good for company users as it allows software companies to integrate it into their own applications and redistribute it.During the converting of PRN to PDF, please contact us as soon as possible.
