Printing Locally using JQuery & CUPS

Hi folks.

I recently developed a solution where a user pushes an F-key (F12) and instructions go to a Dymo printer to print shipping and return labels.

http://images.google.com/images?q=dymo+turbowriter&ie=ISO-8859-1&oe=ISO-8859-1&biw=1164&bih=1127&sei=wyTpUe-zM8LhygH_soD4CA

It's pretty neat. Now I realize that when I was developing, the printer was on the same machine as Lasso. So the OS_process goes into the server, not the client user machine where the printer will be set up. My oversight. Ya it's funny until you realize you still need a solution.

Anyway, I thought I'd ask the list to see if anybody knows how to print locally. I'm up for any options. Please accept my gratitude in advance.

In the meantime, this is how I operate the system currently. It's a slick solution, but the instructions are taken up by the server, not the client.

- I have a session where two svars are the mailing address and the local address

- I use JQuery AJAX to bring in the mailing address when F12 is pressed, and the return address when F13 is pressed. F12 marks the record as "shipped".

<script src="http://code.jquery.com/jquery-2.0.2.min.js"></script>
</head>

<script language="Javascript" type="text/javascript">

$(document).keydown(function(e){
if (e.keyCode == 122) {
$('#target1').load('printlabel.lasso');
// alert('label');
return false;
}
});

$(document).keydown(function(e){
if (e.keyCode == 123) {
$('#target2').load('printReturnLabel.lasso');
// alert('return');
return false;
}
});

var('returnLabel') = '123 Mystreet
Torontonia, Ontaria
Canadania M4M 2Y3';

var('statement') = '-d DYMO -o media=Custom.28x89mm -o orientation-requested=5';

$statement = $statement->split(' ');

if(true);
output_none;
inline(-username='moose', -password='moosehair');
log_warning('inside print label');
var('os') = os_process( '/usr/bin/lp', $statement );
$os->write( $returnLabel );
$os->closeWrite( );
$os->read( );
$os->close( );
/inline;
/output_none;
/if;

var('d') = date;
$d = $d->format('%-h:%M %p');

'Return printed at ' + $d + '<br>';

Cheers
