Is there an XMP tag for recording the scanner used to digitize a print?

I want to store metadata about the scanner used to scan a photographic print. I checked the common XMP namespaces such as dc, xmp, iptcCore, and iptcExt, but I can’t find a standard field for scanner make/model or scanning software. Is there an official XMP tag for this, or is a custom schema the usual approach?

You are right: there isn't one. I suggest using this custom schema: http://analogexif.sourceforge.net/help/analogexif-xmp.php, because at least you will be consistent with what someone is doing (and enough people doing that is the genesis of many standards).
Specifically, the relevant tags are:
ScannerMaker (Xmp.AnalogExif.ScannerMaker)
String value. Scanner manufacturer, for example Epson.
Scanner (Xmp.AnalogExif.Scanner)
String value. Scanner model including manufacturer, for example Epson Perfection 4490 Photo.
ScannerSoftware (Xmp.AnalogExif.ScannerSoftware)
String value. Scanner software, for example Silverfast.

Generated from our catalog & community — verify before relying on it.
There doesn’t appear to be a standard XMP tag in the commonly used dc/xmp/IPTC schemas for recording scanner hardware used to digitize a print. In practice, a custom XMP schema is the usual solution.
One community-used option is the AnalogExif schema, which includes fields such as:
Xmp.AnalogExif.ScannerMaker— scanner manufacturerXmp.AnalogExif.Scanner— scanner modelXmp.AnalogExif.ScannerSoftware— scanning software
Using an existing custom schema like this is preferable to inventing your own field names, because it improves consistency and makes future interoperability more likely. If you need scanner metadata in XMP, that’s a sensible approach.
