1. SCOPE
This specification describes key operations of the B-EP2 and B-EP4 portable printers (hereinafter
collectively referred to as “B-EP”) using their keys and the LCD display.
2. OUTLINE
The key operations are performed roughly in two modes: online mode and system mode. In online
mode, where the printer is connected to a host device such as a personal computer, the key operations
are performed mainly to pause or restart the printer and to display printer status messages and error
messages on the LCD. In system mode, the key operations are performed mainly to conduct a self-
test and to make various parameter settings. This specification describes the key operations in these
two modes.
For explanation purposes, this specification uses English key names and LCD messages of the B-EP,
although other languages are available for key names and LCD messages.
