Many Adobe Reader users have complained that the Poster option is greyed out or unresponsive on macOS.
When you go to Advanced Print Setup and try to uncheck Print as Image, the app tells you that you can’t do that because you’re running Beta macOS software, even though you’re not.
Let’s explore what you can do to resolve this issue.
Poster Option Deprecated from macOS Sonoma Onwards
If the Poster option stopped working after you installed macOS Sonoma, we have some bad news for you, especially if you’re in the sewing community and Reader is essential for your needs.
The PSNormalizer tool has been deprecated from macOS Sonoma and beyond. Now, the only available option is Print as Image.
Poster printing was never supported with Print as Image anyway.
⇒ Quick Tip: If you need to quickly print a PDF poster, you can easily do it on Windows. Adobe Reader fully supports poster size printing on Windows.
If you can’t use a Windows computer or have this problem on a macOS version before Sonoma, follow these troubleshooting steps.
Roll Back Adobe Reader
Install an older Adobe Reader version and check if you can print in Poster size again. Maybe your app version is not compatible with your current macOS version.
On Mac, go to the View menu and select Disable New Acrobat. That should revert the app back to the old interface.
Another handy workaround is to convert your PDF file to PNG. Many Adobe Reader users have confirmed that the option to print poster size is available for PNG files.
Open your PDF image in the Preview app. Then, click on the File menu, select Export, and choose PNG or JPEG as the file type.
If the PNG format is not visible, hold the Option key and click the Format menu to list additional file format options. Save your converted file under a new name in a different location.
This brings us to the end of this quick guide. We hope it answered your questions, even though the news isn’t that good.
