I am having a bit of trouble with a Napster client I am writing (using deprecated's MP3::Napster module)

The napster.pl client included with MP3::Napster uses a similar sub to the one below to recieve a list of names in the channel: 


   109  sub names
   110  {
   111          unless ($nap_object->channel){
   112                  print qq-No current channel\n-;
   113                  return;
   114          }
   115          foreach ($nap_object->users) {
   116                   printf "\t([ %-20s ]) (%-9s)(%4d)\n",$_,$_->s
+haring,$_->link;
   117          }
   118  }

However, this returns: Argument "DSL" isn't numeric in printf at perl/duskster/test.pl line 116. I was informed that printf is unecessary in perl, and that there are far better ways to do it. Any suggestions/fixes will be greatly appreciated :)
