Text only?  Makes a difference, yes.  Been using that with Brother 
printers and OpenVMS for a while, and it works.  telnet and lpr/lpd are 
the older mechanisms for printing; traditional Unix printing ports, and 
used by a variety of platforms.

Postscript didn't work the same as did telnet and lpr/lpd, and DEC 
didn't integrate that Postscript support but rather decided to make it 
an add-on and variously an extra-cost add-on (q.v. "DCPS-OPEN"), and 
we'll be dealing with the fallout from those decisions for the 
forreseeable future.

IPP is a far more recent iteration of printing, and IPP has some 
definite benefits over what went before.  Among other benefits, IPP a 
way for the host to ask the printer what it's capable of providing.  
Secure connections via IPPS, too.
