When printing digital files was in its infancy I was working for Nikon Inc. as a sales rep. At some point and I really cannot remember the time frame, Nikon was making really superb film scanners which produced a digital file on a computer.
Unfortunately there were no digital labs that could print these files and the only in camera store labs were only printing from film. That opened the door to companies like Canon and Epson to develop printers that could be used in the home or studio for printing a reasonable print.
Nikon was in the forefront with all of this by supplying all of the sales reps with Epson printers, papers, and of course inks and trained everyone to do in store demos by setting up a computer, printer and scanner on the counter, in a store, to make digital prints from customers slides and negatives.
All of that quickly moved to doing the same for digital cameras and the printer industry took off like a bat out of hell.
I printed and printed and printed in all sizes until I realized that I would have to move into a much bigger living space in order to hang all of the prints I was turning out. I also realized that I was shooting less, printing more into all hours of the night. It was no longer fun nor was it particularly productive. It sure was very expensive. Printer mamanufacturer virtually gave away the printers so they could sell lots of ink and paper.
Fast forwarding to today, I really have no great desire to print pictures, and fortunately there are all kinds of print labs that will print pretty much anything you want. Some of the print labs even provide profiles for their in store printers that you can use with your post processing applications.
The article I am linking you to is about the Fuji Instax Printer which uses an instant type of film in a printer that can print images wirelessly that are sent from cell phones, cameras such as the Fuji X line, and they produce a small print that can go nicely into a photo album like we used to do. I have all kinds of albums from my parents that they put hundreds of pictures into over the years about their lives and their families lives.
That does not mean you should not go to your local photo lab and get your images printed so you can put on tables and walls, but the Fuji Instax does make it easy to create coffee table albums with the most important memories of your lives.
The printer is so small that it can fit into a small coat pocket or camera bag. As a matter of fact I have a friend shooting with her mirrorless (Fuji) to check out her shot whether it be architecture, landscape, or portrait to make sure she is going to get exactly what she wants in her composition.
It is also nice from time to time to leave an image behind for someone you took a picture of.
Check with your local camera store. Most dealers stock it. If they do not then they are available through lots of mail order providers.
