Well it finds a blank page. <br>

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

If you were unaware of that, then you somehow missed hearing about te
main distinction, main attraction, and most famous feature in the CUPS
engine. So, if so, you should tool around in those pages and get to
know them.</pre>

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.<br>

You found that where? Is this a file on your system? If so, what file?

Among other things, that in no way clarifies whether you have the
Gutenprint RPM package installed -- just that CUPS _expects_ to print
to the thing using a Gutenprint filter/driver.</pre>

<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:<br>
[bliss@bliss ~]$ rpm -qa | grep -i gutenprint<br>
gutenprint-ijs-5.2.10-1pclos2014<br>
lib64gutenprint2-5.2.10-1pclos2014<br>

gutenprint-cups-5.2.10-1pclos2014<br>

and for foomatic<br>
[bliss@bliss ~]$ rpm -qa | grep -i foomatic<br>

One thing I note:
DeviceURI dnssd://EPSON8E2DF7._printer._tcp.local/
Ugh. ZeroConf network transport. I would never, ever rely on that.
Any of the alternatives is less flakey and easier to diagnose.</pre>

<pre class="moz-quote-pre" wrap="">
Well, it's your call wether you want to give up on your printer, but you
might want to do basic hardware diagnosis before throwing it away.
Does the LCD display screen indicate a hardware problem? Does the
<a class="moz-txt-link-freetext" href="http://localhost:631/printers/">http://localhost:631/printers/</a> screen appear to show the printer as
online and reachable? Does it pass a self-test?[1] Can you have CUPS
send it a test page and have it comply?</pre>
</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.<br>

<br>
All I see there is a blank page with a vertical line about 1/5
of the way from the left side of the screen.<br>
<br>
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.<br>

Have a pleasant weekend.<br>
