You know that '<a class="moz-txt-link-freetext" href="http://localhost:631/printers/">http://localhost:631/printers/</a>' is a URL intended
to be
<br>
parsed and acted upon by Web browser software, right? And,
since you
<br>
keep talking about CUPS and your work setting up printers, I'd
assumed
<br>
you know the most famous, best-known thing about it, which is
that it
<br>
puts up a local administrative WebUI for the local system
administrator
<br>
at <a class="moz-txt-link-freetext" href="http://localhost:631/">http://localhost:631/</a> . <a class="moz-txt-link-freetext" href="http://localhost:631/printers/">http://localhost:631/printers/</a> is,
<br>
obviously, a subpage where known printer objects (queues) are
listed and
<br>
can be configured. Moreover, CUPS displays there whether the
printer in
<br>
question has been recently reachable or not, and permits the
admin user,
<br>
if he/she wishes, to send test pages to the queue(s) shown, and
to check
<br>
on and (if desired) cancel pending print jobs in the queue(s).

If you were unaware of that, then you somehow missed hearing
about te
<br>
main distinction, main attraction, and most famous feature in
the CUPS
<br>
engine. So, if so, you should tool around in those pages and
get to
<br>
know them.
<br>
</blockquote>
Actually I never claimed any knowledge of CUPS but that it is
the tool
<br>
generally used by GNU/Linux distribution to establish connections
to
<br>
printers, When it works it works very well but when it fails it
is difficult
<br>
to understand why.

You found that where? Is this a file on your system? If so,
what file?
<br>
It looks like it could be your /etc/cups/printers.conf file --

mystified about why specifically you posted that.

<br>
Because that is what I could find.

Among other things, that in no way clarifies whether you have
the

<br>
If the Gutenprint package is not installed I have wasted a lof
of download time.
<br>
But using the command you recommended here is the result:

Any of the alternatives is less flakey and easier to diagnose.

Well, it's your call wether you want to give up on your printer,
but you
<br>
might want to do basic hardware diagnosis before throwing it
away.
<br>
Does the LCD display screen indicate a hardware problem? Does
the
<br>
<a class="moz-txt-link-freetext" href="http://localhost:631/printers/">http://localhost:631/printers/</a> screen appear to show the printer
as
<br>
online and reachable? Does it pass a self-test?[1] Can you
have CUPS
<br>
send it a test page and have it comply?
<br>
</blockquote>
<br>
It has printed nothing* and the LCD screen does not allow for
much non-maintenance information.
<br>
*That includes running the usual test page, the self-test of
the nozzle pattern and the print head cleaning
<br>
routine.

All I see there is a blank page with a vertical line about 1/5

As I may have mentioned elsewhere I will try another
distribution on the printer to see if perhaps some
<br>
reaction can be coaxed from the NX515.
