Printer Linker is an online directory of service providers useful to designers and design students. Printer Linker, lists: printers, material suppliers, binders, laser cutters, signers and photo labs across Melbourne, including businesses without physical store fronts.
For the foreseeable future Printer Linker is a free service, I Domenico Mazza, run off my web server on the side. It's also been the subject of my Honours research into user interface design—you should click around and try the site on different devices in landscape and portrait.
If you have a business you'd like to recommend for the list or any comments, do get in touch via firstname.lastname@example.org.
