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

  • 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 <windows.h>
#include <string.h>
#include <stdio.h>
int WINAPI VeryPDFPCLConverter(const char *lpCmd);
void main(int argc, char *argv[])
if(argc < 3)
char szCmd[2048] = {0};
for (int i = 1; i < argc; i++)
strcat(szCmd, "\"")
strcat(szCmd, argv[i]);
strcat(szCmd, "\" ");

printf("%s\n", szCmd);


If  you need to know more, please check them in the download package. And there are more examples for VB and others.
