7.0 Fiscal Software and Hardware Interface Information
7.1 Supported Printer Typefaces
The following bigtop print modes are supported:
•
12 CPI, single high
•
12 CPI, single high, emphasized
•
15 CPI, single high
•
15 CPI, single high, emphasized
•
15 CPI, double-high
•
15 CPI, double-high, emphasized
The print typeface is controlled by the application program by setting the required bits in the command
extension.
The selected print typeface applies to all characters of the same line.
7.2 Error Conditions
Errors encountered during command execution are processed as follows:
•
Command processing is suspended.
•
Internal accumulators and counters are restored to their original value (the value they had before the
command in error was received).
•
An error is included in the final status sent over the communication link. The error type indicates the
cause of the abnormal termination.
•
The application program can send the same command again (retry) or send any other command that is
valid for the procedure in progress.
To warn the operator that the same line could appear more than once for the same item, an overlay string
# # # is provided by microcode.
This overlay operation is activated when the device driver sets the retry bit in the repeated command.
In response to a retry operation from the application program, the retry bit is set, allowing the # # # string to
overlay the characters on the slip.
The retry bit has effect only on the following commands, but it may be used on all other fiscal commands
with no adverse effect.
The string # # # overlays the first three characters of the printed line.
