Digitalrevolution IPP library

A library to aid using the ipp protocol in php, for example to send print jobs to print servers that support the protocol

Installation

composer require digitalrevolution/ipp

Usage

Initialize the library

    $server = new IppServer();
    $server->setUri('https://cups.local');
    $server->setUsername('admin'); // optional
    $server->setPassword('admin'); // optional

    $ipp = new Ipp($server, new Psr18Client());

Print a file

    // define a printer        
    $printer = new IppPrinter();
    $printer->setHostname('my.printer');
    
    // print a file on the selected printer
    $ippFile = new IppPrintFile(file_get_contents('/dir/file.ps'), FileTypeEnum::PS);
    $ipp->print($printer, $ippFile);

Fetch job attributes

    $printJob = $ipp->print($printer, $ippFile);
    $updatedPrintJob = $ipp->getJobAttributes($printJob->getJobUri());

Register a printer with cups

    $printer = new IppPrinter();
    $printer->setHostname('my.printer');
    $printer->setDeviceUri('my.uri');
    $printer->setLocation('location');

    $ipp->printerAdministration()->createPrinter($printer);

Delete a printer

    $printer = new IppPrinter();
    $printer->setHostname('my.printer');

    $ipp->printerAdministration()->deletePrinter($printer);

Get Printer attributes

    $printer = new IppPrinter();
    $printer->setHostname('my.printer');

    $response = $ipp->getPrinterAttributes($printer);
    $attributes = $response->getAttributes();
    $printerName = $attributes["printer-name"]->getValue();

Creating a custom IPP operation

This project is created to be easily extensible, adding a new IPP operation is as simple as making sure it has an identifier in IppOperationEnum
Then adding any Job, Printer or Operation Attributes as required by your standard.
Finally sending the request and parsing the response using the standard parser.

class MyOperation
{
    public function __construct(private readonly IppHttpClientInterface $client)
    {
    }
    
    public function myOperation(): IppResponseInterface
        $operation = new IppOperation(IppOperationEnum::OperationType);
        $operation->addOperationAttribute(new IppAttribute(IppTypeEnum::Charset, 'attributes-charset', 'utf-8'));
        
        // set your attributes
        
        return $this->client->sendRequest($operation);
    }
}
