Use
If a label does not print, check the printer's display to see if it shows a receiving status. If so, press Escape to exit receiving mode. Once you see “Online Ready” on the display, print a test label again. If this does not print or the printer does not display “Online Ready,” the unit is locked up. Turn off the printer, wait fifteen seconds and then turn it back on.
If the printer displays “Online Ready,” but is not printing, verify that the parallel port settings did not change. The Parallel Port setting should be “Internal” and the Mode setting should be “IEEE1284”. (From the Main Menu, select Setup, Port Settings, Parallel Comm., Port and Mode.)
4. On the test label, verify your IP and WiFi settings. If using an Ethernet cable, the “Wired/Wireless:” value should be “WIRED”. If using RF, the setting should be “WIRELESS”.
Check the “Actual SSID” and the “WiFi Sig Qual”. Is the actual SSID correct? Is the signal quality greater than zero? If the signal quality is 0, you lost connection with the access point. If it is very low, you may be experiencing interference or are very close to being out of range or an access point. A value of 100 is the best you can have for signal quality. You can probably operate at a minimum of 60, but the number of retries is likely to increase.
5. Ping the printer.
If you can ping the printer, it is at least "seen" on the network. If you cannot ping the printer, then ping every device in the path to the printer - access points, routers, etc. If you can ping every device but the printer, the printer needs to be turned off and back on. If some device in the path to the printer cannot be pinged, that device needs attention.
ping <ip address> (i.e. ping 10.1.88.150)
6. Telnet to the printer.
Once you have verified connectivity, telnet to the printer using port 23 (console). This gives you access to console operation of the printer.
