Could you try the "print" command on the kdeprintd module?
This command has the following syntax:

print(QString cmd, QStringList files, bool remove_flag)

cmd: the command to execute, it could be any command
files: a list of files that will replace any "$out" tag in the command
remove_flag: a flag specifying if the "files" should be removed
after command completion

So, in theory, you should be able to do:

print("ls -l", QStringList(), false)
