We have a web application for billing, it gives print from browser. If we give print from browser to dotmatrix printer there will be a speed issue(it pirnts very very slow). So we plan to send raw texts to printer without intervention of browsers print view.
For that i came to know jZebra plugin. It invokes print through java using javascript. By the jzebra tutorial i can append some html and i cant print some text, working fine. like below
<script>
function print() {
qz.appendHTML('<html><table style="font-size:10pt; font-face:\'Courier New\';"><tr>' +
'<td colspan="3">Company Name</td>' +
'</tr><tr>' +
'<td>TIN: number</td>' +
'<td>ADDRESS<br/>SILK SHOWROOM A/C, PADIYUR</td>' +
'<td>STD: 0000000000/td>' +
'</tr></table></html>');
// Send characters/raw commands to printer
qz.printHTML();
}
</script>
The Problem:
While billing im echoing some HTML like products purchase details and total amounts through PHP on a button click event.
How can i append those HTMLs to the above function?
some of code samples here Calling this PHP through ajax : retail_sales_nontextile_add.php
try{
//SELECTING DATA FRO VIEW FROM VI TEMP
$stmt = $pdo->prepare("SELECT * FROM nontextile_purchase_retailsales_wholesales WHERE bill_number = '$bill_no' ORDER BY id ASC"); $stmt->execute();
$results = $stmt->fetchAll();
}
catch(Exception $e){
print_r($e->getMessage());
exit;
}
foreach($results as $result){
echo "<tr style='margin-top:-37px;' class='active'><td class='center'></td>";
echo "<td class='left'>".$result['variety']."</td>";
echo "<td class='right'>".$result['price']."</td>";
echo "<td class='center'>".$result['quantity']."</td>";
echo "<td class='right total'> ".$result['total']."</td>";
echo "<!--<td class='hidden-print center'><a id='retailsale_nontextile_edit' category ='".$result['category']."' variety='".$result['variety']."' price='".$result['price']."' commision_percent='".$result['commision_percent']."' bill_no='".$result['bill_number']."'>Edit</a></td>-->";
echo "<td class='hidden-print center'><a id='retailsale_nontextile_delete' id_to_delete='".$result['id']."' bill_no='".$result['bill_number']."'>Delete</a></td></tr>";
}
echo "</tbody>
</table>
with the above echoed HTML how can i append it in the javascript function? AJAX is HERE:
$.post(
"./php/retailsale/retail_sales_nontextile_add.php",
{ bill_no: bill_no, sale_date: sale_date, category: category, variety: variety, price: price, quantity: quantity, total: total },
function(data) {
$('#print_area').html(data);
}).done(function( data ) {
});
Thanks for ur help....
