Thank for eidan!:) I found another good tool to print topics in chm file. It is CHM2Word. It can convert chm file to word file and print it right now. It's here:http://www.chm2word.com[^]

You can decompile the CHM file to a set of files in the CHM file. I use PowerCHM to decompile and compile it.

How to print the CHM file topics with a batch? My User Manual have no root topic and topic by topic is too annoying... According to Q302505: PRB: Text Missing When You Print "Selected Heading and All Subtopics" from HTML Help http://support.microsoft.com/default.aspx?scid=kb;en-us;302505
