How Can I Send Text (and Not a Text File) to My Printer on OS X? I know about this question (How do I send ASCII text to printer (over USB)?).  But I'm working on something different.  I'd like to be able to send text from within a bash script or Perl script to my printer.

Everything I find tells me about sending a text file to my printer.  Is there any way to send text from within a script?  (That way I don't have to generate the text, save it as a file, then print the file, then delete the file.)
lp is able to read data from standard input, see man lp:


  lp  submits  files for printing or alters a pending job. Use a filename of "-" to force printing from the standard input.


So if you followed the advice given in the referenced question to install a "raw" printer you should be able to run

echo "whatever text you want to print" | lp -d Generic_usbtb -
