The interface was very intuitive to use, as it's easy to navigate between pages of your document. It also allows you to send multiple files at once, which can be handy if you have several documents that need printing. I wish there were more options in terms of changing colors or fonts, but those are minor complaints. We've been using this program since about 2012 now, and we love how quick our turnaround time has become. This product integrates with most email providers so sending jobs through an inbox is seamless.
