I have a problem with UX-43 cashregister. I should change the tax rate from 17% to 12% How can I do it?
I think the correct tax rate is stored to the tax table (cell 3).
At the moment 17% tax rate is roggammed to the one button.

Other problem is that I'm not know what is correct PLU code to the some button. It is possible to print out all information that is programmed to cashregister at the moment?

All information is actual pleased!
