When it comes to autobiography printing in London, specific formatting requirements may vary depending on the printing service provider. However, it is generally recommended to format the autobiography manuscript in a standard file format such as PDF or Microsoft Word. Ensure that the document is properly formatted with consistent font styles, sizes, and line spacing. It's important to include high-resolution images, if any, in the appropriate file format and ensure they are properly embedded in the document. Consulting with the chosen printing service provider or referring to their guidelines can provide more specific formatting requirements.
