As everyone has pointed out, there's no need for an acid stop bath unless your development times are very short <5 mins. If development times are short then you need to stop development very quickly and that would require the acid stop bath. However, most of us are developing for longer times than that.

I would not advise dropping the acid stop bath for printing paper though. It helps keep the highlights clean. I think this is possibly due to the fact that paper develops very quickly and the highlights will begin to dull with over development.
