I wouldn’t be surprised. On the other hand, it does not import other
extensions, such as hplip and foomatic-filters, either.

Did you run guix system reconfigure after adding the packages to
config.scm? Did you try removing and adding the printer again
afterwards?

Does a /var/guix/profiles/system/profile/lib/cups/filter/rastertoqpdl
symlink exist in your filesystem? I think you could try changing the
rastertoqpdl path defined in the system-config-printer configuration (or
CUPS configuration, assuming it’s just a CUPS GUI frontend) from
/gnu/store/… to that path. /gnu/store/ contents are volatile. Again,
just guessing; perhaps the path is hardcoded into the CUPS/splix build
and uneditable.
