Printer-HP-Display

This module allows you to change the value of the ready message (usually Ready') on the tiny LCD display that practically all HP laser printers have. You can also retrieve the value of the currently set message. The module communicates with the printer using Printer Job Language (PJL). See: http://en.wikipedia.org/wiki/Printer_Job_Language

At the moment this module is just a fun project; somewhat on the lines of ACME::LOLCAT. For example, at Cricinfo we use it to show cricket scores on our printer screen (http://twitpic.com/26yt2d). You should be careful with what you do to the printers at your office - not all IT managers have a funny bone :-).

Here's how you'd use it in you code:

use Printer::HP::Display;

my $printer_ip = "192.168.0.1";
my $printer = Printer::HP::Display->new($printer_ip);

my $message = "I am ready. Are you?";

$printer->set_display($message);

print $printer->get_display; #currently set message
print $printer->get_status; #complete dump of PJL INFO STATUS command
