I want to create a virtual printer driver for Windows. How and where can I start properly? The WDK has some printing drivers examples that do not seems a good introductory. MSDN also doesn't seems to be very helpful for a novice.
There are a lot of virtual printers for Windows out there (mostly they generate PDFs), I wonder if someone could tell my how can I do the same?
Any links to the elaborating documentations are appreciated in advance.
Thanks.
When I did it (which about 12 years ago) I started with the postscript driver sample, replaced all the postscript-specific stuff (in my case, to write to a bitmap instead of generating postscript commands).
I also wrote a custom print monitor (the driver writes to the spooler, which write to a monitor): my monitor wrote to a file instead of e.g. to the parallel port.
However, printer driver architecture and/or the set of sample drivers may have changed since then.
You can look to the 'minidriver' development in the from Microsoft (Microsoft MDT), that might help depending on your exact needs. If the port you need to deal with (ie: you are going to take the data from an existing printer driver and want to process) you could look to the source code for RedMon. It doesn't support Vista/Win7 but might point you in the right direction.
This book maybe help you Developing Drivers with the Windows® Driver Foundation

One of the drivers you mention is open-source (GPL), maybe you could explore its source or adapt it: http://www.pdfforge.org/products/pdfcreator/download
Someone else already mentioned PDFCreator. Here's a more specific link to their code that's creating the printer, port and monitor. Despite being in VB, I can follow it as someone more used to C++, so I guess you can too. modPrinter.bas does the leg work. modMain.bas, from about line 28 onwards, calls into modPrinter.bas.
Create a Print Port Monitor, associate that port with a printer, and you'll get the data the printer driver sends to the port.
working example of how is it done in Cpp and java can be found here: http://www.mms-computing.co.uk/uk/co/mmscomputing/device/printmonitor/index.php
