IBM 4610-TM6 - SureMark Printer TM6 Two-color Thermal..., User Manual

Page: 61 / 236

This is the default mode. See “Message from the printer” on page 165 for the
format of printer to system messages, which include a byte count, status bytes, and
optional extended status bytes or user data.
XON and XOFF signals are always transmitted independently and are not inside
any part of the message, including the byte count, status bytes, or user data. When
a message includes optional user data, the byte count (bytes 1 and 2) can include
X'10', X'11', or X'13'. When X'10', X'11', or X'13' occur in transparent XON/XOFF
mode, the byte count is bit-exclusive-OR’ed with X'21' and is prefixed by the DLE
(X'10') character to become:
Value in message Becomes
X'10' X'1031'
X'11' X'1030'
X'13' X'1032'
User data with X'10', X'11', or X'13' is also treated this way in transparent
XON/XOFF mode. The byte count is not incremented for such extra characters.
Determining XON/XOFF control
You can determine whether or not XON/XOFF control is being used by sending the
extended address command and checking bit 3 of the feature byte. If this bit is set,
the printer is in XON/XOFF mode. (See “Extended address command–request
printer ID” on page 109.
Disabling XON/XOFF transparent mode
You can disable transparent XON/XOFF mode as described in “Real-time requests”
on page 161. When disabled, X'10', X'11', or X'13' can occur within messages. The
values are not bit-exclusive-OR’ed with X'21' because no transform occurs for such
values within messages as it does during transparent XON/XOFF mode.
Note: Disabling XON/XOFF transparent mode should be done with Model TI4 only.
It is not recommended for Model TI8.
USB communication mode
No switches or special commands are required for USB communication. With the
USB interface card and cables in place, the system automatically detects the printer
when it is attached and performs any necessary setup. The printer operates at data
rates up to 12 Mbps.
USB selection
Universal serial bus (USB) is an industry standard communication interface. It is
used to attach devices, such as printers, displays, and keyboards, to personal
computers or IBM POS systems that have USB ports. The standard USB port (with
a power brick) is used to attach the SureMark to personal computers. The powered
USB port is used to attach the SureMark to IBM POS systems. See Figure 9 on
page 21 for the thermal/impact SureMark printers and Figure 10 on page 22 for the
single-station SureMark printers.
