The most significant collection of affected printer drivers that we’re aware of are those for Brother printers. We’re exploring a number of options regarding how we can support those. If you’re aware of drivers other than Brother that are in this situation, please let us know what they are so we can assess those as well.
We can and should make the 32-bit nvidia drivers available as part of the amd64 packages. These would then be exposed into the 32-bit containers, ensuring that the 32-bit userspace libraries matched the version of the kernel driver, regardless of what other library versions were available as packages within the container.
