How can I make `enscript` block till the printer finishes its job?

The following command will create a pdf file under ~/PDF/: enscript -B -P PDF bloom.c I want to move the output pdf file here mv "ls -dtr1 ~/PDF/* | tail -1" . But I can't run the mv command immedately follow the enscript command, because enscript sends the input file to the printer PDF, and returns immediately before the printer finishes creating a pdf file. A very bad solution is to insert the following command between the two commands sleep 5 It is bad because I don't know how long I shall wait. Note that I know there is other better way to do the same thing without having to run the mv command after enscript, but I just wonder if there is any way to make enscript block till the printer finishes its job? I remember having similar thoughts for other commands besidesenscript. I am assuming that enscript doesn't provide such an option, so would be interested in whether bash or other program can make that happen. Signal handling might be a solution, but I don't know which signal to catch.
