<?php

 
	echo $p = printer_open("EPSON TX121 Series");
	printer_set_option($p, PRINTER_PAPER_FORMAT, PRINTER_FORMAT_A4);
	printer_start_doc($p, "My document");
	printer_start_page($p);
	$pen = printer_create_pen(PRINTER_PEN_SOLID, 1, "000000");
	$font = printer_create_font("Courier", 37, 19, PRINTER_FW_NORMAL, false, false, false, 0);

	printer_select_pen($p, $pen);
	printer_select_font($p, $font);

	printer_draw_line($p, $i,0,$i,6700);
	printer_draw_text($p,$i,$i,0);

	printer_draw_line($p,1, 150, 1000, 0);
	printer_draw_text($p, "ครัวอาหาร", 125, 0); // x,y


	printer_delete_font($font);
	printer_delete_pen($pen);
	printer_end_page($p);
	printer_end_doc($p);
