How to print directly from printer with Yii?

问题

How do I print directly from printer?

This is a intranet web application. The user will use this application and they will print out the report from the printer of their department (different department, different printer). I'm Googling to print out directly from printer, but I can't find anywhere. I'm using Yii Framework 1.11.

How can I do this? Is it possible to print out directly from printer? How?

回答1:

You can try this:-

$fhandle = fopen("test.php","rb");
$contents = fread($fhandle, filesize("test.php"));
$output = eval($contents);

$handle = printer_open("Dell Laser Printer M5200");
printer_set_option($handle,PRINTER_MODE,"raw");
printer_write($handle,$output);
printer_close($handle);

For web application all print works has dependency with your browser. You have to create a page or popup window just for print view with special Html and css.

My View (index or something)

    <p align="right">
        <?php 

            echo CHtml::link('New Job',array('create'),array('class'=>'btn btn-info'));
            echo CHtml::link('Print',array('print'),array('class'=>'btnPrint btn btn-info', 'style'=>'margin-left: 10px;'));
        ?>
    </p>
<?php $this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'job-grid',
    'dataProvider'=>$jobs->search(),
    'filter'=>$jobs,
...)); ?>

My Controller

public function actionPrint() {
        $d = $_SESSION['all'];
        $this->renderPartial('print',array('d'=>$d),false,true);
}

My model

public function search()
    {
        // Warning: Please modify the following code to remove attributes that
        // should not be searched.

        $criteria=new CDbCriteria;

        $criteria->compare('id',$this->id,true);
        $criteria->compare('name',$this->name,true);
        $criteria->compare('date',$this->date,true);
        $criteria->compare('department_id',$this->department_id);
        $criteria->compare('section_id',$this->section_id);
        $criteria->compare('team_id',$this->team_id);
        $criteria->compare('created_date',$this->created_date,true);
        $criteria->compare('updated_date',$this->updated_date,true);

        $data = new CActiveDataProvider(get_class($this), array(
                'criteria'=>$criteria,
                'pagination'=>false,
        ));
        $_SESSION['all'] = $data;

        $data = new CActiveDataProvider(get_class($this), array(
                'pagination'=>array('pageSize'=> Yii::app()->user->getState('pageSize',
                        Yii::app()->params['defaultPageSize']),),
                'criteria'=>$criteria,
        ));
        $_SESSION['limited'] = $data;

        return $data;
    }

My view (print.php)

<div id="summary">
<table width="100%" border="1">
    <tr>
        <th>No.</th>
        <th>Job No.</th>
        <th>Date</th>
        <th>Department</th>
        <th>Section</th>
        <th>Team</th>
    </tr>  
    <?php   
    $i=1;
    foreach($d->data as $item)
    {
    ?>
    <tr>
        <td><?php echo $i;?></td>
        <td><?php echo $item->name; ?></td>
        <td><?php echo $item->date; ?></td>
        <td><?php echo $item->departmentsdep->name; ?></td>
        <td><?php echo $item->departmentssec->name; ?></td>
        <td><?php echo $item->departmentstea->name; ?></td>
    </tr>
    <?php 
        $i++;
    }
    ?>
</table>
</div>
