Delphi: Fix bug in printer driver

I have a printer driver, which interacts with a web service. Something goes wrong in this interaction and I need someone to fix it. I believe that this is a tiny issue, since I have gotten people to write other software towards the same web services and that software works well, and also the printer driver interacts with other parts of the same web service (authentication etc.) without problems. The bug could be either in the printer driver or the PHP web service. You will get access to all source code and a test server. The first part of this job will be to modify the Delphi printer driver to so it interacts with our test system instead of our production system (a simple replacement of a URL). I also need you to create a switch in one of the .INI files of the printer driver which will be named USE_TEST_SERVER=1 That switch will switch between the test and the production server. I will not accept bids of more than 60$, but you are welcome to retract your bid once you see the source code. If you complete this project successfully, I will ask you to make at least 2 more projects on the printer driver. One of these projects will be to get the printer driver to automatically check for updates every time it starts and seamlessly auto-update. This will be a major feature worth 200$ to me.
