[PLUG] "Unable to locate printer"

[Dick Steffens]

I have a Brother MFC-7820N printer (network) installed on my Ubuntu 14
machine with CUPS. It used to work. It works from my wife's Win7
machine. I can see it in the CUPS Printers page with a status of: Idle -
"Unable to locate printer."

Any ideas on what I need to do to fix this?

In the meantime, I can copy files to my wife's machine and print from
there, but that's a nuisance.

Dick,

Two things: First, in the CUPS admin page under either maintenance or
administration look for an option to restart the printer. If that's not
present or resolving the problem proceed to the more involved fix.

Second, delete the printer and re-add it. Copy the parameters if need be
before deleting the definition. I've needed to do this a few times over the
years and it always results in a working printer that CUPS recognizes.

Good luck,

Rich

I didn't find exactly what you described, but I did find:

On the page for the printer, under the Maintenance drop down list,
"Pause Printer"
After pausing the printer that option changed to "Resume Printer"

Things are now back to normal.

Thanks!

Dick,

That's because I was working from memory well past its best-use-by date.

On my CentOS 6 machine, cups defaults to 'stop on error', which may be
why you had to do a resume. I recently dug into the printer options and
changed this to something like 'retry on error'. You may want to do the
same.

Thanks. I'll look for that.
