I use an old rotary cutter blade to cut the paper. The paper I used was 18" wide, so I cut 6" strips across the paper, then cut the 6" strips into 3 - 6" squares. Using normal inexpensive copy/printer paper I laid the FP onto the c/p paper, ran a not too hot iron across the top inch of the FP to "fix" it to the c/p paper. One at a time I fed the papers FP side down into my printer and printed the block diagram from my computer.
Have a normal HP printer, scanner, copier with normal ink, etc. No special products are needed.
