This plugin is quite large (over 7Mb), because it contains a lot of code for creating PDF files. Normally, a plugin that you download can be installed and activated in your WordPress dashboard, in the Plugins -> Add New -> Upload page.
If your website gives you an error, telling you that you are not allowed to upload large files, then you can use either of these two methods instead:
- Go to the Plugins -> Add New page in your WordPress dashboard. Search for the plugin “Upload Larger Plugins”, and then install and activate it. Then return to the Plugins -> Add New -> Upload page, and try again.
- Or, unzip the plugin zip on your computer. You will then have a directory called “woocommerce-printnode”. Upload this whole directory via FTP into your WordPress plugins directory (wp-content/plugins). Then visit the Plugins page in your WordPress dashboard and activate the plugin.
