PCL was developed by Hewlett-Packard. (ie the printer command and the hex value that must be sent to the printer). I have got escape sequences for the HP printer. Like, where can i find the escape sequences (hex value and printer command) for the EPSON and CANON printer? Are the escape sequences for CANON and EPSON (ie.,hex value and printer command) differ or same as the Hewlett-Packard printer.
