Blank page after image

[sv1gzf]

After printing an image label we get a blank page.

we solved the issue with this fix

/**
* Compress a row of ASCII hexadecimal data.
*
* @param string $row
* @param string $lastRow
* @return string
*/
protected function compress($row, $lastRow)
{
//if ($row === $lastRow) {
// return ':';
//}

    $row = $this->compressTrailingZerosOrOnes($row);
    $row = $this->compressRepeatingCharacters($row);

    return $row;
}

I can't seem to reproduce that. The line you commented out simply returns a colon if the current row matches the last row (and omits the current row). The total number of rows (height of the image) should be the same.

Can you supply a sample?

I'm using this code
$client = new Client('192.168.4.204');
$zpl = new Builder();
$zpl->fo(0,0)->gf(new Image(file_get_contents('voucher.gif')))->fs();
$client->send($zpl);
$zpl = new Builder();
$zpl->fo(0,0)->gf(new Image(file_get_contents('receipt.gif')))->fs();
$client->send($zpl);

OR

$client = new Client('192.168.4.204');
$zpl = new Builder();
$zpl->fo(0,0)->gf(new Image(file_get_contents('voucher.gif')))->fs();
$zpl->fo(0,0)->gf(new Image(file_get_contents('receipt.gif')))->fs();
$client->send($zpl);

Attached you can find the labels

When I un-comment these lines
//if ($row === $lastRow) {
// return ':';
//}

I get an extra blank page after the first label.

Any luck with this ?
