PL/SQL command to print a saved file in unix?

I've created and written a file to a unix directory using a stored procedure. Is there a way through that same stored procedure to send that file to a printer.

Right now I'm using lp -d 1_it_zeb overpack_lbl.txt to print the file from a command prompt. How would I send this same command to unix using my procedure?

Thanks!
CraigOne method is to create a pipe on unix that performs a specific task, say printing in your case. The following example shows a pipe that is created such that it compresses that file being written to (in this case, PL/SQL).

#--Setup the pipeline to be used in the export process
mknod $dmp_file_name p
compress < $dmp_file_name > $dmp_file_name.Z &

You should be able to formulate a pipe to send the contents to a printer.

Or, you could set up a cron job to look at files being generated and once completed, send it off to the printer.
