I need some php or javascript script first to display a PDF file in a HTML modal (client browser) and then to print a PDF file from html modal (client browser) to a standard paper size thermal printer whose dimensions (left, margin, top, bottom margin will be hardcoded)

Output result is to print a receipt for restaurant order on a thermal printer or order receipt (PDF file) could also be sent to email. I already have a script that generates order as a PDF file and save it on a server and attaches to a email then sent. I just need php or javascript script to display PDF file as a preview in a html modal and then to let client print the order receipt to a thermal printer.

How can I achieve this?

My Answer:
To achieve this, you can use a combination of HTML, CSS, JavaScript, and PHP. Here's a general outline of how you can implement this:

1. Display PDF file in a HTML modal:
- Use a library like PDF.js to display the PDF file in a HTML modal.
- You can create a modal using HTML and CSS, and then use JavaScript to load and display the PDF file in the modal.

2. Print PDF file to a thermal printer:
- You can use a library like Print.js to print the PDF file to a thermal printer.
- Make sure to set the paper size and margins in the print settings to match the thermal printer's dimensions.

3. Send PDF file to email:
- You can use PHP to send the PDF file as an attachment in an email.
- Use the PHP `mail()` function or a library like PHPMailer to send the email with the PDF attachment.

Here's a basic example of how you can implement the above steps:

html







Open PDF Modal

Print PDF

This is a basic example and may need to be customized based on your specific requirements and setup. Make sure to replace `'path/to/your/pdf/file.pdf'` with the actual path to your PDF file. Additionally, you may need to adjust the PDF.js and Print.js settings to match your thermal printer's dimensions and print settings.
