We hear all the names but let's sort it out!
OK the real name of those great cash registers that used to be named Samsung is SAM4s not SAMS cash registers or anything else. Their models begin with ER, SER, or SPS like the ER-650, the SER-7000 or the SPS-530
Now lets look at the Sharp models. It is just plain old Sharp not Sharpe Cash Registers or Sharper Cash Registers. Models start with XE, ER, or UP however XE is the consumer line NOT the commercial line. STAY AWAY FROM XE MODELS UNLESS YOUR STORE IS SMALL AND YOU DON"T DO MUCH VOLUME!
