On the left side, directly above the BOM grid, there are three buttons dedicated to exporting and printing.
The first, exports the BOM in different file formats. You can choose between:
For exporting to Excel you can activate multiple options such as two preview types and file properties, see here.
The second, creates a preview where you can see how the BOM grid looks on the press sheet and you can also print directly to the default printer.
The third, prints directly to the default printer without any preview.
If you want a different order of the grid columns, you need to open the configuration manager and change the order in the configuration list and then update the BOM again.
