Hello, thank you for your answer first. Unfortunately this does not work for me. Then I get on the one in the invoice line(s) only the entry format(L. note or ") or removeParentNode. And this also, if Article in the bill are, at least the costs 0.01 Euro. An error in the Change I close time, since I have used copy and paste. On the other hand, I should like that, the line at a price of 0 Euro in so far as is maintained. Only the price should not be printed, if it is less than 0.01 Euro is located. Building here is once again an example. In the moment, it is so that Article x with price 0 Euro is pressed. Article x 0Euro but it should be so:

article X

Article Y 15.00 Euro.

change the [[ formatLang(l.price_subtotal, dp='Account', currency_obj=o.currency_id) ]] expression in invoice template (account_print_invoice.sxw) by:

[[ (formatLang(l.price_subtotal, dp='Account', currency_obj=o.currency_id) <> 0) or removeParentNode('tr')]]

In that case you only get the invoice lines with a non-null total
