+# Print All Posts
+
+[](https://github.com/phpbbmodders/printallposts/actions/workflows/tests.yml) [](https://github.com/phpbbmodders/printallposts/actions/workflows/lint.yml)
+
+Lets users who can print topics in a forum print every post in a topic on one page.
+
+## Features
+
+- Adds a **Print all** link to the **Topic tools** menu, next to phpBB's own **Print view**. It opens in a new tab.
+- phpBB's print view shows one page of posts at a time. **Print all** shows every post in the topic on a single printable page.
+- Uses phpBB's existing **Can print topic** forum permission. Users without it don't see the link and can't open the page.
+
+## Screenshots
+
+
+
+
Print all in the Topic tools menu
+
Every post on one printable page
+
+
+
+Click a screenshot for the full size.
+
+## Requirements
+
+- phpBB 3.3.19 or later
+- PHP 8.3.36 or later
+
+## Installation
+
+1. Copy the extension to `/ext/phpbbmodders/printallposts`
+2. In the Administration Control Panel, go to **Customise → Manage extensions**
+3. Enable the **Print all posts in a topic** extension
+
+### Upgrading from `rmcgirr83/printallposts`
+
+This extension used to be Rich McGirr's `rmcgirr83/printallposts`. To move to this version:
+
+1. Disable the old **Print all posts in a topic** extension in the ACP. Do **not** delete its data.
+2. Upload this version to `/ext/phpbbmodders/printallposts` and enable it. The new version won't enable while the old one is still on, and it removes the old extension's entry from the extension list when it is enabled.
+3. Delete the `/ext/rmcgirr83/printallposts` folder and purge the board cache.
+
+If you disable the old extension from the command line (`bin/phpbbcli.php`) instead of the ACP, run `bin/phpbbcli.php cache:purge` before enabling the new one; the command-line disable doesn't clear the cache.
