Edit History

Dear experts,

Is possible to edit invoice.tpl to generate invoice with english named products? (sometimes appear the second language names)
I found this:   <td style="text-align: left;">{$order_detail.product_name}</td>    but here nothing related to language.
I have two langauge installed on shop, but the invoices I need in one language.
I use PS 1.7.7

Thank you!
