who said the web protocols aren't "totally custom" in relation to other web protocols for sending a file to print?
now there's standards like bluetooth for printing that don't need driver, but suck for various reasons.
even still, the only time anyone I knew personally printed anything from a mobile device was over 10 years ago and that was in an electronics store, printing goatse over bluetooth to a printer on display.
so I don't really get it how mobile is the norm, most people print from some pc or another still - even connecting their mobile device to said pc to move the data they want to be printed.. because fck, whoever printed something as a message to a printer thats sitting at their home or girlfriends home? yet that's what is in the stupid adverts.
now let me tell you what is the real BREAKTHROUGH inkjet printing technology: hacked printheads with tubes for ink coming from external tanks. shit cheap per page! I can keep printing all day every day and it costs pennies! well it costs almost just the paper. and here in asia that sems to be the norm, everyone who buys an inkjet buys it with a hacked cart and ink reservoirs.
