Airprint won't print USPS postage label barcodes

I just bought an HP Laserjet which was on Apple's supported list for Airplay printers. When printing a postage label, the barcodes will not print. The label looks fine in the iOS "print preview", and everything prints fine except the barcodes. Switching between color and B&W does not fix the issue.

Printing the same label from Windows connected by USB works fine. Printing the same label from Windows over the network works fine.

The HP printer firmware, HP printer software, and the iPhone SE2 are all fully updated to the latest.

Any ideas for troubleshooting?
