Print Pages document

"I can see the document in Drive,"

Does this mean you can see the contents of the document in an application named "Drive," or that you can see the name of the file containing the document in a finder window showing a location in your MBPro's hard drive?

To print a Pages document, you need to open the document in Pages, then Print.

That may not be possible, depending on the versions of Pages on the two Macs in use.

What version number of the OS is installed on the 2020 machine?

What version number is the Pages application on which the document was created?

Same questions for the OS version and Pages version on the older Mac, from which you are trying to Print.

OS version can be found via Apple Menu > About this Mac.

Pages version: Pages menu > About Pages.

The message you received is consistent with an attempt to open a Pages document in a version of Pages older than the one on which it was created.

Pages documents are unsupported on Google Drive, and unlike Word documents that Drive is programmed to not think are zip containers, it will attempt to unzip a current Pages document and ruin it.

The current version of Pages (v10.3.5) shows all of the 2009 MacBook Pro models as unsupported hardware, and if that were not enough, you would need Pages v5.6 (El Capitan) or later to open a document created by the current Pages version.

If you are using Pages v5 - v5.2.2 on macOS Mavericks on that 2009 MBP, then that version range of Pages does not know about the current Pages single file (zipped) format documents that were introduced in Pages v5.5.3.
