Support for a newer Greek Type A fiscal checksum ("stream line") has been added. This format can be activated with configuration parameter fiscal_print_new_streamline = typeA3.
This is a NEW configuration parameter. Formerly, stream line type could be set with parameter "fiscal_print_streamline" which accepted values "typeA" and "typeA2". This has been left as-is, because Berlin POS only recognizes these two options.
The new, third option is only supported by online receipts and activating it requires the new parameter fiscal_print_new_streamline = typeA3 must be set.
