The uv command is safer to use than uvsh or dssh in this context, because it takes automatic care of removing defunct printer shared memory segments (and has the authority to do so (provided permissions and ownership on the executables have been set correctly), which uvsh and dssh do not).
Don't forget to execute the dsenv script before attempting to invoke any of these commands. This could be made conditional, say, on testing one of the environment variables that is set in the dsenv script and not re-executing the script if it's not necessary to do so.
