Powering On The Printer
When you power on the printer, it executes a self-test. During the self-test, the
LCD momentarily displays the DPI resolution (203 or 305 DPI) of the installed
printhead. The default power-on state is online. Once the printer has
successfully initialized, the ONLINE status indicator light illuminates, and the
LCD indicates ONLINE, the printer model (SL4M/T4M), the printhead installed
(203 or 305 dpi), the communication interface, and the emulation selected.
