Instead of using my own printer with the ink issues and limited standard print sizes, I organize my smaller prints into a 12" x 12" Costco lay-flat photobook and get a total of 70-ish to 102 square feet of beautiful prints all organized into one affordable & beautiful hardcover book, where I often have a single 24" x 12" print when you turn the page.
For larger prints I use Whitewall (in Germany) Lambda Fuji Crystal DP2 prints and it is absolutely beautiful every time (it is an actual photographic print, not an ink jet print). And I can set the width and height independently to be anything in 0.1" increments up to a max size of 94.5" x 48". And any medium to large size print averages between 5 and 5.5 cents per square inch. My last order had 11 large prints of various shapes & sizes (the largest was 70"x40") and they were all supplied with their own cut-to-fit removable clear protective sheet and then wrapped around a single large hollow shipping tube & protective box and quickly airmailed to me for just $8 shipping. I unwrapped them in pristine shape. You can also pay more to get higher resolution or other options.
The nicest thing is that every single print can be custom ordered to any width and height (and thus any aspect ratio) which means all your prints can be unique to the aspect ratio and size you prefer. I was thinking of covering 1 wall with 4 big prints custom fit to the wall dimensions and avoiding a thermostat in the middle - I'll include a picture of what that would have looked like as an example of what you can do when each print width & height can be independently adjusted in 0.1" increments:
So for those of you that print yourselves, I'm glad you enjoy it. I used to do it, but got really frustrated at dealing with the various ink issues & cost and limited standard sizes. Now I'm amazed at what I can put on my wall or in my bookcase, and never worry about ink issues again.
