Epson C82332 - Manual (Page 59)

Operation
After setting up the card, you can use the routine lpr command
from any host to direct a print file to the Ethernet Card. The card
does not have to interpret any of the incoming print data
whatsoever, allowing binary image files, font download files, as
well as ASCII text to be printed transparently.
The interface card is able to handle many separate communication
channels simultaneously. Unless coupled with a compatible
spooling unit, the Ethernet Card will not have any disk-spooling
capability, so incoming print requests from other hosts when the
card is already servicing a print job are “stacked,” and serviced in
rotation.
The Ethernet Card will respond to an lpq print query by sending
back details of the current print job, as well as all stacked prints. If
a connection request is received after all available connections are
taken up, the card will not respond to the connection attempt.
Note:
An lpq enquiry may show “missing” stack entries; for example, only jobs
2, 5, and 7 appear. The missing entries (3,4, and 6) will be print jobs
sent by a different protocol, such as Novell or Ethertalk.
Printing a file
At the prompt type (example):
lpr -Allison filename or lp-d Allison
