First, it is out of print.
Second, unless you're a programmer, it'll be an extremely dry read.
Third, as someone already stated, it was about printing in Windows. The ISBN has already been posted, and I believe you can still purchase it on Amazon.com.
Finally, it was written when Windows 95 came out, and there have been several changes to the printing API since then. While many of the concepts are still quite relevent with Win32 and Win64 (Vista / Windows 7), there are undoubtedly changes to the API calls that are not documented in the book (due to the date of publication). So, caveat emptor.
