lprng needed by AUCTeX?

[brownh <brownh@historicalmaterialism.info>]

Lprng provides lpr and is characterized as a BSD "spooling system". 
CUPS, on the other hand, is described as a "printing system". I 
installed CUPS but not lpr/lprng. 

I cannot print from AUCTeX:

  Running `Print' on `test' with 
    ``dvips -P hp_Laserjet_1320_series_USB_1  test''
    dvips: warning: no config file for `hp_Laserjet_1320_series_USB_1'
    This is dvips(k) 5.96.1 Copyright 2007 Radical Eye Software

However, I do have /etc/cups/printers.conf that has:

  # Printer configuration file for CUPS v1.3.8
  # Written by cupsd on 2009-09-04 11:39

Does this imply that dvips requires the installation of lpr/lprng in 
addition to CUPS? Is the warning about no config file for my printer 
only the result of not having lpr installed? What is implied here by 
the "broken pipe"?
