Enable Alternate Error Reporting

Description Use this command to enable the printer’s status alternate reporting feature.
• Serial Port
• If an error occurs, the printer will send a NACK(0x15), followed by the error number,
to the computer.
• If no errors occur, the printer will echo ACK(0x6) after last line of the current label
has been rasterized.
• The printer will send a DLE(0x10) when the label is dispensed.
• If paper or ribbon empty occurs, the printer will send, through the serial port, a ”-07”,
“Pnnn” where nnn is the number of labels remaining to print. (Same as US1
command)
• The UT command (when compared to the US1 command) then adds a "Lyyyyy" to
the end, where yyyyy is the number of unprinted raster lines. (07PnnnLyyyyy)
• Parallel Port
• If an error occurs, the printer will print the error number and the printer’s indicator(s)
LED will indicate an error condition. See the individual printer’s user manual for
details.
• Mobile Printers Only (TR220)
• Additionally enables command error reporting via printer’s status indicator. The
indicator is turned off by default for this printer only.
