PDF Invoice

Hello everyone. I want to change my invoice pdf without using any plugins. For example, the pdf logo loaded from the admin panel is at the top and on the edge. I want the logo to cover the top of the page. What is the file path that the invoice was designed for? Is it possible to add other interests besides the information that is available? Thanks in advance.

You need to change in PdfService.cs file.

For change in order invoice see method

PrintOrdersToPdf(Stream stream, IList<Order> orders, int languageId = 0, int vendorId = 0)

You can override PrintOrdersToPdf method in your plugin and make changes in the file.

Maybe these setting can help
