Bug description

When trying to print ZPL code via PrintNode with the following code:


$zplCode = <<<EOT
^XA
^CFA,30
^FO50,300^FDJohn Doe^FS
^FO50,340^FD100 Main Street^FS
^FO50,380^FDSpringfield TN 39021^FS
^FO50,420^FDUnited States (USA)^FS
^XZ
EOT;

$printJob = Printing::newPrintTask()
    ->printer($printerId)
    ->content($zplCode)
    ->send();

I always get the code printed on the label but its not converted.

When debugging the returned $printJob I do see that its contentType is raw_uri and not raw_base64.

How can I set the contentType with the above code to ensure it's correctly printed?
