Data Transfer
A data frame consists of a start bit, seven or eight data bits, 0 or 1 parity
bit(s) and 1 or 2 stop bit(s). With these combinations, 9, 10, 11 and 12
bit frames are available:

Parity
There are three possible parity settings: Even, Odd, None.
`
When Even parity is specified, the interface expects to receive data
frames with even parity and will transmit data with even parity.
frames with even parity and will transmit data with even parity.
`
When Odd parity is specified, the interface expects to receive data
frames with odd parity and will transmit data with odd parity.
frames with odd parity and will transmit data with odd parity.
`
Parity will be checked whenever “Even” of “Odd” parity is selected.
If a parity error is detected, “PARITY ERROR” message will be dis-
played on the LCD. Printer will continue to receive data.

When “No” parity is specified, the interface does not except data
frames to include a parity bit, and the interface transmits data with-
out parity bits.
