I was browsing in a computer supplies catalogue and noted the Hewlett-
Packard 3000CP and 3500CP large format printers.  They claim to be good
for poster size images up to 150 feet long.  Expensive machines; UK
price GBP 8000 to 10000.

Obviously getting the right printer is just the start of the solution
but maybe a fellow MMDer has one of these beasts and would be willing
to help the nascent Society of LYric Printers.  (SLYP - it's what the
paper does in a friction feed ;)
