Replacing an 86XX or 3400 Printer

The 3440 printer provides compatibility with the 3400 printer and the earlier
8636 and 8646 bar code printers. The 3440 printer operates in Advanced
mode or 86XX Emulation mode. The two modes have three operational
subset modes: Print mode (contains configuration commands), Program
mode, and Test and Service mode.
Both Advanced mode and 86XX Emulation mode operate on the same basic
command set for print, configuration, program, and test and service
commands. On initial power up, the 3440 printer is in Advanced mode.
Advanced mode provides new features that make the 3440 compatible with
the 3400 printer. When you select 86XX Emulation mode, the 3440 printer is
compatible with the 8636 and 8646 printers. In 86XX Emulation mode, some
of the Advanced mode features are not available.
Differences Between 86XX Printers and Emulation
Mode
While the 3440 printer can emulate most functions of the 86XX series
printers, there are some features that are different or not implemented. This
section identifies those differences.

No BEL Status Response

The 86XX printer checks all incoming messages for errors before storing
them in the data buffer for later execution. When it receives an erroneous
message, it sends a BEL character back to the host as the printer status
response and discards the whole message. It continues to process the next
message without explaining to the host why it discards the previous
message.
The 3440 printer software does not ignore messages that have errors in any
of the commands. Instead, it executes all the commands as best as it can,
ignoring invalid commands and using printer defaults for erroneous
parameters. As a result, the printer treats mandatory data fields like
optional data fields. Attempting to execute all commands, in spite of errors,
gives the user clues about what went wrong and what they can do to
remedy the problem.
