Adding columns for printing

When creating Sales Invoice, there are Tax fields. On printed invoice there are no tax fields.

  1. How can I add (select) more fields to printed invoice (ex: tax, tax amount)
  2. I want to create additional table, with totals, but grouped by “Tax Code” as well, ex:
No. | Description |  Price without tax |   Tax   |  Tax amount | Total.  |
 1. | Service 1   |              1.000 |    5%   |          50 |  1.050  |
 2. | Service 2   |              1.000 |   10%   |         100 |  1.100  |
                                                         Total |  2.150

Additional table:

Total without tax | 2000
           5% tax | 50
          10% tax | 100
            Total | 2150

This is already being considered for implementation in Manager. Search the forum for various topics related to the same.

This already appears in Manager when you have unchecked the Amounts are tax inclusive option.
