Yes.  Line Printer Daemon (LPD) is a well-established, legacy
standard.  It uses port 515 and is governed by IETF RFC1179: 

  http://www.ietf.org/rfc/rfc1179.txt  

The new IETF standard is the Internet Printing Protocol
(IPP).  It uses port 631 (both clear and SSL) and is governed
by IETF RFC2910:  
  http://www.ietf.org/rfc/rfc2910.txt  

Another port to be aware of is port 9100, commonly referred
to by it's vendor-centric names like a "HP JetDirect" port. 
The technical name is the [HP] Page Description Language
datastream (PDL-datastream) port.  Microsoft calls it a
"TCP/IP port", and you set it up as a local port, which maps
back to the IP address/port.

BSD/SysV UNIX LPD, LPR and LPRng offer LPD services.

CUPS offers IPP by default, and it can also offer LPD
services.
CUPS, as a client, can also use other methods including LPD,
IPP, SMB, PDL-datastream, etc...
CUPS also offers a replacement spooler for NT/2000/XP that
radically simplifies/centralizes administration for Windows
clients.

Windows Servers can offer SMB and LPD, and newer versions can
offer IPP services.  Windows NT/2000 clients can use SMB, LPD
and PDL-datastream, with XP adding IPP.  For IPP, LPD and
PDL-datastream, you set it up as a "local port."

Macs can also use LPD and PDL-datastream, with newer MacOS X
releases supporting IPP.
