Hello,

Please go to the Settings -> Technical -> Paper format and change output dpi 90 to 105 it will solve your issue.

if you not using specific format for report then change A4 paper format.

in such case you have to customize the report using xml:

try this code:

 <t t-if='product.product_description_sale'><div class="text-muted"  t-esc="product.product_description_sale[:70]+'..' if len(product.product_description_sale)&gt;72 else product.product_description_sale "/></t>

here i have restricted the size to be max of 72 character(if len(product.product_description_sale)>72) , after that it will print "....."
