JobManager::send() must implement interface Smalot\Cups\Model\PrinterInterface

[BrunoFelipeAlbuquerque]

After installing and trying to use any of the example code, I'm getting the following error:

Fatal error: Uncaught TypeError: Argument 1 passed to Smalot\Cups\Manager\JobManager::send() must implement interface Smalot\Cups\Model\PrinterInterface, boolean given, called in /var/www/cups/index.php on line 29 and defined in /var/www/cups/vendor/smalot/cups-ipp/src/Manager/JobManager.php:87 Stack trace: #0 /var/www/cups/index.php(29): Smalot\Cups\Manager\JobManager->send(false, Object(Smalot\Cups\Model\Job)) #1 {main} thrown in /var/www/cups/vendor/smalot/cups-ipp/src/Manager/JobManager.php on line 87

Well it seems like the parameter you assigned when calling send() is not an actual PrinterInterface but is false. I propose you examine the parameter and check if it actually is implementing the PrinterInterface.

the same error:

problem in printer name "...../HP-Photosmart-C4380-series" in sample code. My printer name is "...../ML-371x-Series"

but now i have other error:

UPDATE: after call function $client->setAuthorizetion('login', 'password') all work fine.
Thanks to lib author

the same for me

Argument 1 passed to Smalot\Cups\Manager\JobManager::send() must implement interface Smalot\Cups\Model\PrinterInterface, boolean given, called in /var/www/html/ipp_test/test/app/Http/Controllers/testController.php on line 37

my code

$client = new Client();
$builder = new Builder();
$responseParser = new ResponseParser();
// $client->setAuthorizetion('login', 'password');

    $printerManager = new PrinterManager($builder, $client, $responseParser);
    $printer = $printerManager->findByUri('ipp://192.168.10.232:631');
    
    $jobManager = new JobManager($builder, $client, $responseParser);
    
    $job = new Job();
    $job->setName('job create file');
    $job->setUsername('demo');
    $job->setCopies(1);
    $job->setPageRanges('1');
    $job->addFile('./helloworld.pdf');
    $job->addAttribute('media', 'A4');
    $job->addAttribute('fit-to-page', true);
    $result = $jobManager->send($printer, $job);

You both are aware that the Client class method for authentication in CUPS is called setAuthentication and not setAuthorizetion ? Because you both use this wrong method, $client seems not to authenticate and the $printerManager probably returns false instead of a connected printer. And because of this you probably can't send the job via $jobManager->send().

[boomsya]

:) yes, you right
setAuthentication. sorry for my mistakes. Maybe at that time i was works hard and tired
