Hello,
I suppose you are asking to reduce the size of the report.
1 - In Manager go to Database > Registers > Receipt Formats > POS Receipt Format and open properties.
Find Reports "X Z ZZ...." and open properties.
If this gives you options to view or hide sections do so for the ones that interest you.
Otherwise you stack with it. You need to edit the XML file and select it as in 1.
Remember if you decide to experiment with XML editor backup the original file.
