The publishing business relies heavily on the use of PS files, and it is truly the case that much of that industry would not be able to get as far as it has without the use of PS files. It is one of those things that we all need to recognize as important to the fundamental development of a particular industry like this. Before PS files came along, it was completely impossible to have printed text and images side-by-side. It is hard to imagine that in today's day and age, but it was something that could not happen in the past. The good news is that PS files have made it easier than ever to accomplish putting printed text and images on the same page without the problems that previous generations ran into before. Those worries are a thing of the past at this point. Take some time to appreciate the true power of a PS file when possible.
