"If you read my previous article, you may have noticed that
I haven't given a protocol to send the compressed data to the

including disabling and re-enabling interrupts for the critical
parts, you will have to run it as root (superuser). Please don't
consider this program a gem, not even an alpha-level software. It's
just a hack for showing that is possible to construct a device
driver for the printer."
