Here is my module, I probably have a lot of mistakes, sorry but I'm new around here and I really want to be able to develop in odoo

Hii,
You need to change xpath 

Try like this ,

<xpath expr="//header/button[@name='print_quotation']" position="after">
     <button string="Orden de Trabajo" type="object" name="print_work_order"/>
</xpath>

Correct me,If I am wrong
Thank you
