Can I get a consolidated z read?

[Deli-cious]

Hi everyone. I currently have my main till with built in printer and an iPad which is used for inputting orders. Issue is both seem to have independent shifts and I can’t cash off on the iPad as the sales don’t show on the main machine, and I can’t print an end of shift sales report for those sales as the iPad isn’t connected to a printer. I only want to cash off card sales obviously so no need to open the till drawer.  Anybody offer a solution? Thanks in advance.
