[cups.general] how to print directly to network printer using command line lp... ?

[Norm Jacobs]

Presumably, you will not be able to print to it directly with the CUPS 
client commands.  The last time I looked carefully at their 
implementation, they made some CUPS specific IPP requests before they 
actually used the IPP print-job or create-job/send-document sequence.  
It's unlikely that your printer implements the necessary CUPS IPP 
extensions, but stranger things have been known to happen. 

There are implementations of IPP that would allow you to send your job 
data directly to the printer.  The CUPS ipp backend module is one, the 
OpenPrinting PAPI implementation is another, and I expect that there are 
others.  You might also be able to send your job data over a raw TCP 
socket connection (usually to port 9100) or port 515 using rfc-1179 
protocol.

This all begs the question, why do you want to bypass the queue?
