The ZT230 printer is not printing, and the status light is amber. How can I diagnose this connectivity or paused state error?

An amber status light often signifies a paused state, a data error, or a communication issue. First, check the printer's display for specific messages like "Paused" and unpause it if necessary. If it's a network printer, verify the Ethernet cable is securely connected, check the network settings (IP address, subnet mask) on the printer's display, and try pinging the printer's IP address from your computer. For USB connections, ensure the cable is secure, and the correct printer driver is installed and selected on your computer. Power cycling both the printer and the computer can often clear temporary communication glitches. Also, check the print queue on your computer for any stuck print jobs.
