Thus spake Ryan Yagatich (ryagatich () CSN1 COM):

With the HP LaserJet 4 series Jet direct card you can telnet to port
9099 on the printer's IP address and type any text and on disconnect
the page will be printed. If someone writes a piece of software that
is like a dictionary generator and pushes it to this port, and then
kills the connection later, it is possible to DOS your print services.
why? well no paper/toner so you have no service.


Oh, they changed the port?
I am used to port 9100.
