Using Postscript, one can generate something like:
The "perforations" are round, but when converting the PDF to a JPG, they became square :-(. The text on the white background isn't bold either.
The output you see is created by a postscript program that follows. Don't look too close, it's my maiden postscript speech. It constructs a background (the contform procedure) at the beginning of each page, reads a text file (/tmp/passwd) and prints it at 6lpi on your default page format (in my case A4). To execute this script, start it with ghostscript (gs) or ghostview (gv). When you save the script as /tmp/contform.ps, then
gs /tmp/contform.ps
or
gv /tmp/contform.ps.
The script:
