This is a most excellent place for technology news and articles.
In a lot of densely populated Asian cities, you can print to the shared printer of a local convenience store through the network without bringing a USB drive. You submit the job, it gets stored in the queue of the device, you go to the store (usually just downstairs from your apartment), scan a QR code, and the job prints. You can even pay online - it's great!
