C# Integration with Barcode Printers

Question

Hi,

 

I am developing now an application that will generate barcode for items and I need the application to print this barcode and I don't have any experience how to integrate with printers.

 

My question what I need to use barcode printers?

Is this a straightforward? or need to know more about Printer API?

 

I've already see articles about specific model "EPSON L90" and its APIs but I need more examples to see how to walkthrough.

 

Thanks 

Answer 1

Hi Praveen, 

 Thanks for your reply. 

   But in my situation,  it is not a DLL Hell Problem because am creating 2 dlls  at a time with a different name and different functionality and also in this dlls are not added in Registry Editor, it's saved only my application folder.

   I want Add Reference from A DLL to B DLL.

 

   public virtual Tuple<bool, string> isValid(Dynamic_Val_001)

   {

      return new Tuple<bool, string>(false, "Success");

   }

 

Dynamic_Val_001  is A DLL Class Name 

 

    

 

 

Answer 2

To my understanding I think its like DLL HELL problem.

 

This kind of scenerio is generally termed as dllhell problem. 

Here is what it is,

 

1. I have 2 applications, A1 and A2 installed on my computer.

2. Both of these applications use shared assembly shared.dll

3. Now, I have a latest version of Application - A2 available on the internet.

4. I download the latest version of A2 and install it on my machine.

5. This new installation has over written Shared.dll, which is also used by Application - A1.

6. Application - A2 works fine, but A1 fails to work, because the newly installed Shared.dll is not backward compatible.

So, DLL HELL is a problem where one application will install a new version of the shared component that is not backward compatible with the version already on the machine, causing all the other existing applications that rely on the shared component to break. With .NET versioning we donot have DLL HELL problem any more.
