Printing directly from web without header and footer

we have a website that displays a ticket. This ticket at this time is being printed to a thermal Zebra printer using a PDF file. This is to avoid header and footer configurations. Need to convert the script to send directly to printer without using the PDF in the middle of the process, to give a better customer experience and also to control the page size and page break witouth setting up the printer manually. Basically, need an application to print a ticket without header and footer. Information is already being displayed in a popup window. Everyting in application is solved but the print procedure. Please write PM for further clarification.
