I have developed many responsive website and various software on .NET platform. My recent software is to capture the data from print spooler and extract some data from it and upload to an excel file. Whenever any printing command is to be given to the system (from any software), the said software will capture the data in real time from the printer spooler and after decoding it from PJL (printer job language PCL3 GUI and other format) and extract some data (product list and quantity) and upload these data into an excel file.
