What are some common methods for printing PDF files using PHP in a local network?

Printing PDF files using PHP in a local network can be achieved by utilizing tools like TCPDF or FPDF to generate the PDF file, and then sending it to the printer using a network printer's IP address. This can be done by using the shell_exec() function in PHP to execute system commands for printing.

// Specify the path to the PDF file to be printed
$pdfFilePath = 'path/to/your/pdf/file.pdf';

// Specify the IP address of the network printer
$printerIP = '192.168.1.100';

// Use shell_exec to send the PDF file to the printer
shell_exec("lp -d tcp://$printerIP $pdfFilePath");
