replace the part you call your description field in the report with the code in my answer.

you probably have added something like this :

<span t-field="o.YourdescriptionField"/>

instead, add my code and tell me if it works for you.

@Ibrahim, where do I find the area to modify ? In a python file or in a settings (where in this case?)

@ibrahim, I suppose we are talking about this code: can you please highlight which line I should modify :

Problem comes precisely from this : <tr>

<th>Description</th>

<th class="text-right">Quantity</th>

<th class="text-right">Unit Price</th>

<th t-if="display_discount" class="text-right" groups="sale.group_discount_per_so_line">Disc.(%)</th>

<th class="text-right">Taxes</th>

<th class="text-right" groups="sale.group_show_price_subtotal">Price</th>

<th class="text-right price_tax_included" groups="sale.group_show_price_total">Total Price</th>

</tr>

</thead>

This get overlap on the second page by the product description which continue from page 1 to page 2
