If you use the "print-at-copy-shop" versions, they recommend one like FedEx-Kinko. Most of the patterns can be printed at home and assembled. At first, it seemed like such a chore, but when I figured the cost of gas to drive to the nearest shop (roundtrip of 70mi) cost of printing, and postage or waiting and paying parking fees, the time and paper involved gradually became a LOT more acceptable. As to size, if you are referring pattern size (12-14-16) you draw the size(s) off after the pattern is completed. If you refer to paper size, I use letter/A4 and a home printer. The cost of ink, paper, tape for a 50-sheet pattern comes to less than a nickel. I do buy the cheap stuff, less than $3.00/ream. If I know I won't make that pattern again, I cut it apart and print something on the back. I found that using the B-side of a pattern for a different pattern can get very interesting. Now, puzzles, craft directions, and grocery lists go on used paper. My DIL just got us a shredder from her company's surplus & obsolete employee's sale. Shredding in cross-cut I found out, will reduce the time and increase the efficiency of decomposition for that which is finally used up. I hope all this will answer some of your questions.
