Printer control language, PCL for 24bpp, 16 an gray - c++

Question

I used this link and added lots of enhancements related to GDI.
https://github.com/microsoft/Windows-driver-samples/tree/master/print/OEM%20Printer%20Customization%20Plug-in%20Samples/C%2B%2B/bitmap
The above samples generates a bitmap driver with output as a bitmap image. Now using the bitmap I am able to generate working PCL for monochrome. I need some help for enhancing it further to generate PCL for 16bpp, 24 color and gray scale
Can anyone suggest some samples where I could see the PCL commands written in C++?
The monochrome part works correctly but the remaining color or gray scale just produce a blank image. I am using GhostPCL to convert to jpeg for testing purposes.
Can anyone provide a sample for where given an appropriate bitmap there is some PCLstream as output?
If you can't provide an entire working sample, how about things in commands which need to be addressed.
The one obvious thing is the buffer, rowsize.
This is the PCL for monochrome.

This is the PCL for TrueColor same document. Nothing is printed except text

Can anyone suggest? I don't have working knowledge of PCL or C++ except learning it like this.
