Printer local IP address (for connecting to local web interface)
14.6 Printer local IP address (for connecting to local web interface)
The printer’s local IP address is used when connecting to theprinter’s local web interface. The local IP address depends uponwhat network the printer is on.
Figure 14.20: Hovering over the LOCAL UI button displays the printer’s local IP address
If your printer is online to the Polar Cloud – connected through alocal network at your site to the Polar Cloud – the Polar Cloud knowsthe printer’s local IP address. Try hovering over the “LOCAL UI”buttonfrom the Polar Cloud’s printer dashboard or printer managementscreen to have your browser display the IP address the Polar Cloudknows; see the lower left of Figure 14.20. Or try clicking the “LOCALUI” button as that will cause the Polar Cloud to attempt to open upa new window to the printer’s local IP address. Note that the PolarCloud’s attempt to connect back to that local IP address fromover the Internet may or may not be permitted due to yourlocal network’s security settings; but even if the Polar Cloudconnection attempt back from the Internet (hence external to yoursite) is not permitted, that IP address to which the PolarCloud attempted to connect is the local IP address whichyou, on the local network, should be able to use to connectto the printer’s local web interface, should you wish to doso.
However, if a Polar3D printer is not configured to connect to alocal network, and is merely running its own WiFi hotspot, then onits own WiFi hotspot the Polar3D printer’s local IP address is192.168.0.1. For a new Polar3D printer, not connected to any localnetwork, see the discussion of connecting to the printer via theprinter’s own WiFi hotspot at step 5 of Section 1.1 in the Polar3DPrinter Guide: you will need to get your device onto the printer’sown WiFi hotspot, on which its local IP address is 192.168.0.1. Ifyou are connecting to the Polar3D printer’s local web interface toperform direct printing (printing without using the Polar Cloud),see the further discussion in Section C.1 of the Polar3D Printer Guide.
If your printer is connected to a local network but your site’sInternet connection is down, so that the printer is not connected tothe Polar Cloud, then (unless your site uses static IP addresses andyou previously made a note of your printer’s static local IPaddress), you may need to ask your network manager to tell youyour printer’s current local IP address. In particular, if yoursite’s local network uses DHCP (dynamically assigned) IPaddresses, your printer’s local IP address may change from time totime. The Polar Cloud notes the IP address your printer hadwhen connecting, so that is why when your printer is online tothe Polar Cloud the Polar Cloud can tell you your printer’scurrent local IP address (regardless of whether your localnetwork allows external connections, such as from the PolarCloud, back to that local IP address); but when your printer isdisconnected from the Polar Cloud, the Polar Cloud will notbe aware if your printer’s local IP address happens to havechanged.
