This is a very good book for those interested in controlling the parallel port interface on the PC. The most common usage is for cheap/inexpensive data acquisition or control, but the book also covers "LapLink" type transfers, high speed printing and device chaining. In my opinion, this books greatest strength is that all of the code is provided in Visual Basic, Delphi and C. Visual Basic and Win95/WinNT cannot directly control the printer port, so the authors have made a library of routines for use with any language, thus filling a hole that exists in Visual Basic. Anyone who wants to directly control the parallel port from Visual Basic will find everything they need (both on disk and in instruction) in this book.
