Hi,
I just created a barcode image generator where I found out in internet, when I test it and I print it in a ordinary printer it was okay. Same size, what the barcode display on my web page is the same size of what I got printed, but when I tried to print it on Zebra Barcode Printer its become small and only half was printed.
this is my code:
<?php
$bc = new barCode();
$bc->build($_GET['id']);
$q = new MySQL();
$q->Fetch(wms_receiving);
class barCode
{
public $bcHeight, $bcThinWidth, $bcThickWidth, $bcFontSize, $mode;
// function __construct($mode='gif', $height=25, $thin=1, $thick=3, $fSize=2)
function __construct($mode='gif', $height=75, $thin=1, $thick=4, $fSize=3)
{
$this->bcHeight = $height;
$this->bcThinWidth = $thin;
$this->bcThickWidth = $this->bcThinWidth * $thick;
$this->fontSize = $fSize;
$this->mode = $mode;
$this->outMode = array('gif'=>'gif', 'png'=>'png', 'jpeg'=>'jpeg', 'wbmp'=>'vnd.wap.wbmp');
$this->codeMap = array(
'0'=>'010000101', '1'=>'100100001', '2'=>'001100001', '3'=>'101100000',
'4'=>'000110001', '5'=>'100110000', '6'=>'001110000', '7'=>'000100101',

);
}
public function build($text='', $showText=false, $fileName=null)
{
if (trim($text) <= ' ')
throw new exception('barCode::build - must be passed text to operate');
if (!$fileType = $this->outMode[$this->mode])
throw new exception("barCode::build - unrecognized output format ({$this->mode})");
if (!function_exists("image{$this->mode}"))
throw new exception("barCode::build - unsupported output format ({$this->mode} - check phpinfo)");
$text = strtoupper($text);
$dispText = "* $text *";
$text = "*$text*"; // adds start and stop chars
$textLen = strlen($text);
$barcodeWidth = $textLen * (7 * $this->bcThinWidth + 3 * $this->bcThickWidth) - $this->bcThinWidth;
$im = imagecreate($barcodeWidth, $this->bcHeight);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
imagefill($im, 0, 0, $white);
$xpos = 0;
for ($idx=0; $idx<$textLen; $idx++)
{
if (!$char = $text[$idx]) $char = '-';
for ($ptr=0; $ptr<=8; $ptr++)
{
$elementWidth = ($this->codeMap[$char][$ptr]) ? $this->bcThickWidth : $this->bcThinWidth;
if (($ptr + 1) % 2)
imagefilledrectangle($im, $xpos, 0, $xpos + $elementWidth-1, $this->bcHeight, $black);
$xpos += $elementWidth;
}
$xpos += $this->bcThinWidth;
}
if ($showText)
{
$pxWid = imagefontwidth($this->fontSize) * strlen($dispText) + 10;
$pxHt = imagefontheight($this->fontSize) + 2;
$bigCenter = $barcodeWidth / 2;
$textCenter = $pxWid / 2;
imagefilledrectangle($im, $bigCenter - $textCenter, $this->bcHeight - $pxHt, $bigCenter + $textCenter, $this->bcHeight, $white);
imagestring($im, $this->fontSize, ($bigCenter - $textCenter) + 5, ($this->bcHeight - $pxHt) + 1, $dispText, $black);
}
if (!$fileName) header("Content-type: image/{$fileType}");
switch($this->mode)
{
case 'gif': imagegif($im, $fileName);
case 'png': imagepng($im, $fileName);
case 'jpeg': imagejpeg($im, $fileName);
case 'wbmp': imagewbmp($im, $fileName);
}
imagedestroy($im);
}
}
?>
I don’t have any idea how can I print my barcode image in Zebra. Is this any configuration?
Thank you
