Remove PDF padding / margin

i am trying to remove the thick padding / margin that is there , please advice how to do that .

Below is the screenshot of the pdf generated by erpnext . i just need to reduce the margins , No margin is also fine .


You can create a Custom Print Format and set the padding to whatever you like. This will work fine in case of normal Print, but not in PDF.

i have finally solved it . The css does take styles while exporting to pdf but erpnext seems to be caching and making html and css files of its own , due to which you cannot see changes instantly . so after every css change you make . just run the following commands and then see the output.

Edit this file /home/user/erpnext/apps/frappe/frappe/utils/
edit lines 66,67,139,142
put values 0mm.

the run the following code one by one

bench clear-cache
bench clear-website-cache
bench build
bench restart
bench start

You will get a pdf with no margins and padding

attaching a screenshot

Whoever needs code for my template you see in screenshot , send me a message and i will send it to you , cant seem to add it here .
