I love that it allows me to upload my posters in high quality format so they can be used for future events without having them printed again. It's very simple, easy-to use software which makes great looking poster designs within minutes! Nothing really negative about this program; however if you are considering using an online printing service make sure your expectations match what is offered by their website/service as there may just not have been any upgrades or design changes since when we were last involved with these services years ago - many of our requirements at work didn't suit well anymore than 10+ yrs later (in fact some never did!).
