After sending I realized there were two pieces of information I forgot
to include that might be of interest towards diagnosing the difficulty:

1.) The printer is a SCX-4200 and is listed as working on
openprinting.org.

2.) the slice of the error message I showed was incomplete: the guix
package where rastertoqpdl is being searched for is in cups, yet the
tool is clearly available in the splix package. Why is
system-config-printer looking in the wrong package? How can I make the
service see both?

Thanks,
