Question

我使用http://www.barcodebakery.com使用zebra p2824 +打印机打印条形码，有些用户说条形码有时不会扫描。

并非每个人都会这样;但是有一个人有2台打印机，他们都没有工作。他们能够打印其他扫描程序的条形码;但这些条形码偶尔也不会扫描。

输出：

条形码创建：

    $text = rawurldecode($this->input->get('text'));
    $barcode = rawurldecode($this->input->get('barcode'));
    $scale = $this->input->get('scale') ? $this->input->get('scale') : 1;
    $thickness = $this->input->get('thickness') ? $this->input->get('thickness') : 30;

    $font = new BCGFontFile(APPPATH.'libraries/barcode/font/Arial.ttf', 10);
    $color_black = new BCGColor(0, 0, 0);
    $color_white = new BCGColor(255, 255, 255);

    // Barcode Part
    $code = new BCGcode128();
    $code->setScale($scale);
    $code->setThickness($thickness);
    $code->setForegroundColor($color_black);
    $code->setBackgroundColor($color_white);
    $code->setFont($font);
    $code->setLabel($text);
    $code->parse($barcode);

    // Drawing Part
    $drawing = new BCGDrawing('', $color_white);
    $drawing->setBarcode($code);
    $drawing->draw();
    header('Content-Type: image/png');
    $drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

HTML / php输出条形码：

for($k=0;$k<count($items);$k++)
{
    $item = $items[$k];
    $barcode = $item['id'];
    $text = $item['name'];

    $page_break_after = ($k == count($items) -1) ? 'auto' : 'always';
    echo "<div style='width: 2in;height: .8in;word-wrap: break-word;overflow: hidden;margin:0 auto;text-align:center;font-size: 10pt;line-height: 1em;page-break-after: $page_break_after;padding: 10px;'>".$this->config->item('company')."<br /><img src='".site_url('barcode').'?barcode='.rawurlencode($barcode).'&text='.rawurlencode($barcode)."&scale=$scale' /><br />".$text."</div>";
}
