Hi,

Easily what you can do is that, hide the report from the print by giving menu="False" inside the report tag(which you shown in the question) and print the same report from a button in the header of the form. Once you add the button in form and use it for printing, you can easily make it visible and invisible using the attrs .

<report
     id="action_report_batch_product_config"
     string="GuiLherme Configuration Configuration"
     model="stock.picking.batch"
     report_type="qweb-pdf"
     name="teste2"
     file="teste2"
     menu="False"
     print_report_name="'Batch Product Config- %s' % (object.name)"/>

Add a button to form view,

<button name="print_picking_new" string="Print" type="object" class="oe_highlight"/>

then in the model,

def print_picking_new(self):
    return self.env.ref('module_name.action_report_batch_product_config').report_action(self)

Now the print button will be visible always, for making it visible and invisible you can add attrs and give condition, a sample is given below,

<button string="Configure Variants" type="action"
    name="%(product_attribute_value_action)d"
    attrs="{'invisible': ['|', ('attribute_line_ids', '&lt;=', 0), ('is_product_variant', '=', True)]}"
    groups="product.group_product_variant"/>

Thanks
