Pearl: Modify text screen on HP 4100-4200 Laserjet Printers

/ Published in: Perl

I found this script online and thought to myself, "I must use this in the office!" All you need to do is create a name_of_file.pl file, and execute this command in your terminal. $ name_of_file.pl "Insert message"

# hpsetdisp.pl  
  # Connects to a JetDirect equipped HP printer and uses 
  # HP's control language to set the ready message on the
  # LCD display.  Takes an IP address and message on the
  # command line. My favorite message is "INSERT COIN".
  # Keep in mind the limitations of the display when composing 
  # your clever verbiage.
