I don’t have a poster printer. I used to in a previous life, but now I don’t print enough to really warrant a giant printer lurking in a closet. Trying to figure out how to print a wall poster is way more math than I want to do on a regular basis.
Going back through my bookmarks this morning, I located a great tool that makes wall posters perfectly. And, best of all, no math! BlockPoster allows me to select any image, upload to the site, select the number of sheets of paper I would like, and it gives me back a file to print perfectly. Best of all, I can do border-less printing or allow for a white border to create a more mosaic look.
Simple, cheap posters with just three quick steps. I don’t think I could ask for a better tool than BlockPoster.
