Answer 1

You need to 'start' the document, then create a new page whenever you need (don't forget to 'end' it.), then end the doc.

printer_start_doc($handle, "Document name");

printer_start_page($handle); // Start page 1
// here goes the content of page 1 via printer_write
printer_end_page($handle); // Close page 1

printer_start_page($handle); // Start page 2
// here goes the content of page 2 via printer_write
printer_end_page($handle); // Close page 2

printer_end_doc($handle);
