Jake where would you stand on the position of using a lab that put you in the position of effectively hitting the print button, and having the lab's printer spit out the print form the machine, with them doing nothing but package the print and post it to you? In the situation where you would have to pay the thick end of $500 for a decent 17" printer, and your best deals on paper and ink were the normal US RRPs? Over here we can't even get Red River papers, they won't ship to the UK, for us printing at A3+ at home is quite an expensive proposition, From what I understand even with the dye inks of the Pro 100 you still need to be printing at least once a week to keep the printer healthy and avoid having to waste a lot of ink in printer maintenance functions. With digital all the real work is done in the computer before the data goes off to the printer, I just don't see what is so special about installing the ink and filling the paper tray on your own machine when it costs so much to own. Don't get me wrong at the prices available in the US it is a lot more reasonable when you compare those costs between running your own printer, and time sharing a remote device.
In the days of analogue photography it was a very different situation, and as you say probably a large majority of keen photographers never set foot in a darkroom, and had no real understanding of the post processing that photography required, as seen by the number of photographers that see digial PP as being something that is "wrong" or "unnatural" believing that you should do as they did with film, and get it right in the camera, since that was the only control that they had, giving it all away to those running the lab they used, be it a local drug store, a specialist high street one hour service or a lab that you sent your film off to, either fully automatic, or a pro lab. I was not one of those, having had my own home darkroom, processing and printing black and white as well as developing my own E6 slide and printing from them using CibaChrome.
I am not against sending prints out.
The question i answered was 'why would anyone want to print themselves"
Offering reasons why one would want to print themselves is a totally different position from "no one should send prints out"
