Hi mossblaser, thanks for the kind words and taking the time to outline a fix! I've just implemented your fix in the PKGBUILD and published a new pkgrel.
I'll also update the pinned comment to make it clear that the package should work with the Arch version of CUPS.

I just set this up on a new computer, and lpadmin kept crashing when trying to add a printer using this driver.
Edit on 18th of Jan: Thanks to mossblaser, I've implemented a fix in the PKGBUILD (3.0.0-5) which should allow this driver to continue to work with Arch's version of CUPS.
Alternatively, you can use the printer with the IPP Everywhere driver, and the URI ipp://<IP>:631/ipp.
Replace <IP> with the IP of your printer. I'm leaving this comment here for posterity, and for anyone who runs into a similar issue.
