you need to speak to your printer manufacturer. i know nothing about your printer

happy to hear it.
Do want to share what the issue was here ?
(in case someone else comes across the same issue)

I am looking for a solution too. I don’t have a receipt printer yet, but before I buy one I want to make sure it works.

I’ve read maybe a solution is to change margins to and disable header and footer in the browser (Chrome/Firefox). Maybe you also need to change a small setting in the printer to cut at document instead of page (or the other way around).

Could somebody try this?

Maybe a module fix is needed to end the print with a linefeed or pagebreak.

I have a star printer and the problem is that you need to set a parameter in the printer driver for windows. I think you will need to disable the header and footer as the printer driver will print the order and then feed to the bottom of the page to print the footer. In does not take into account 72mm wide but treats it as A4 hence you end up with about 8 to 9 feet of printing. It is a simple problem that is overlooked. To overcome the Google print issue I used Automatic Print Manager from Namtuk. This can be set up to print to the receipt printer and kitchen printer at the same time. I the print manager I just print the email body and have increased the point size of the print out to 4 so people with bad sight can read the order.
When it displays in the print driver it will show a small receipt with the footer at the bottom don worry this is a function of the printer driver. I wasted about 2 days on trying to configure google print but the simple change in the driver fixed this. sanctuaryparkpizza.com.au is the simple pizza website.
