Each Storefront installation contains the reserved printing options field ‘PrintingQuantity’. If a form filling field with the same name is created, in Storefront versions 8 and below, the values are copied between the two fields even when this extension is turned off. This is inbuilt Storefront functionality.
In Storefront versions 9 and above, all form and printing fields with matching names are automatically copied. However, the functionality is not reliable for pricing. It is recommended to configure price tables to use form filling fields rather than print options and use the extension functionality exclusively for copying quantity (which must always be a printing option).
No known issues at present.
