Operation - Epson C823461 (Ethernet User Manual

Operation

After setting up the card, you can use the 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,
allowing binary image files, font download files, as well as
ASCII text to be printed transparently.
The interface card can 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 lpr 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.
