Network printer from behind a phone?

Is there any reason we couldn't (or shouldn't) hang a network printer off of the PC port of a 7960? The documentation is a little vague ... only stating "other devices".

Thanks.

Re: Network printer from behind a phone? [In reply to]

I would be concerned with the proximity (electrical interference) to the phone. That's about it.

Perhaps there's a possibility of upstream electrical damage, but don't know if there would be any more risk than a PC. Printers do have pretty big power draws so perhaps there is.

If the printer puts unsupported voltage on enet pairs it's going to fry
switches as well as phones. Otherwise, if the printer emits enough emag
it might affect the phone. In that case use a longer cable and move the
printer further from the phone.

I would be more concerned about the fact of the printer losing connectivity when you reset the phone and/or do code upgrades.

Re: Network printer from behind a phone? [In reply to]

More concerned that a PC losing connectivity? Not sure why. Printers nowadays have large enough buffers and they're quick enough to take in jobs, they'll likely continue printing for those short outages. If there even are any.

I think you'd be fine.
