The allignment is changed in the print format when i use pdf view in the print inside the doctype

I choosed the print format and viewed it in its respective doctype. During that time, the allignment is correct. but when touch the pdf at the top right corner in print inside the doctype in erpnext, the allignment become worse.

Hi,
Frappe uses wkhtmltopdf to render PDF files. If you are using custom print formats or HTML blocks within your print format, make sure you webkit-prefix your css.

I didn’t understand . can you please explain it little bit deeper

Could you share a screenshot of your print format / code / print view or anything so I can explain.
