The Toshiba Printer Offline issue can be resolved in a number of different ways. First, check the printer's settings. If the parameters don't yield the desired results, make the appropriate modifications. Inspect your printer drivers for any out-of-date versions and update them as soon as you can, or install the printer driver from scratch.
Make sure the printer is USB-connected to the computer most significantly. The primary reason for this printer offline error is a faulty connection. If the issue persists, restart the device.
