12.9 Logo commands
12.9.1 S
ELECT THE CURRENT LOGO
Selects a logo to be defined or printed. The active logo n remains in use until this command is
sent again with a different logo n, or command 1B40 is sent or printer reboots.
When this command precedes a logo definition, that definition is stored in flash memory as logo
n. if there is already a different definition in flash memory for logo n, the first is inactivated and
the new definition is used. The inactive definition is not erased from flash and continues to take
up space in flash memory.
When this command precedes a logo print command and n is different from the previously active
logo selected, the printer retrieves the logo definition for n from memory and prints it. If there is
no definition for logo n, then no logo is printed.
An application using multiple logos, into flash memory, is responsible for erasing the flash
memory page when the logo area is full.

12.10 Printer status commands
These commands enable the printer to communicate with the host computer. They are stored in
the printer's data buffer as they are received, and are handled by the firmware in the order in
which they were received.
When a fault occurs, the printer will go busy at the communication interface and not respond to
either of the Printer Status commands. If the fault causing the busy condition can be cleared,
such as by loading paper, or letting the thermal print head cool down, the printer will resume
processing the data in its receive buffer.
Real Time commands allow the printer to respond immediately, even though it is busy at the
communication interface. See the following section, Real Time Commands, for details about
these commands.

END PRINTER SOFTWARE VERSION
The printer returns 8 bytes containing the boot and flash software version.
The first 4 bytes returned are an ASCII string for the boot version.
The second 4 bytes are an ASCII string for the flash version.
Example: the printer returns 1.07 1.15
This means the boot version is 1.07 and the flash version is 1.15.

12.11 Real time commands
The Real Time commands provide an application interface to the printer even when the printer is
not handling other commands.
♦ Real Time Status Transmission: DLE (Hex 10) Sequence
♦ Real Time Request to Printer: DLE (Hex 10) Sequence
♦ Real Time Printer Status Transmission
The original Printer Status commands, Transmit Printer Status (Hex 1B 76, ASCII ESC v) are
placed in the printer’s data buffer as they are received and handled by the firmware in the order
in which they were received. If the paper exhausts while printing data that was in the buffer
ahead of the status command, the printer goes busy at the communication interface and
suspends processing the data in the buffer until paper is reloaded. This is true for all error
conditions: knife home error, thermal print head overheating, etc. In addition, there is no way to
restart the printer after a paper jam or other error.
The Real Time commands are provided to overcome these restrictions.
12.11.1 R
ULES FOR USING REAL TIME COMMANDS
Three situations must be understood when using real time commands:
1) The printer executes the Real Time command upon receiving it and will transmit status
regardless of the condition of the host being ready to receive or not.
2) The printer transmits status whenever it recognizes a Real Time Status Transmission
command sequence, even if that sequence happens to occur naturally within the data of another
command, such as graphics data.
In this case the sequence will be processed both ways: as a real time command and as the
graphics data it is intended to be when the graphics command is executed from the buffer. The
result is that the host might receive status messages it has not requested.
3) If the printer is in error condition, meaning that the communication interface is likely to be
busy, the host must be able to send the real time commands regardless of this busy state at the
interface. Otherwise those commands wouldn’t be received and processed.
Page 47
TPOS PRINTER Series User Manual Page 46 /71 Reference: FDE 3107226 Issue B
12.11.2 M
OVING DATA THROUGH THE BUFFER
Applications should not let the buffer fill up with Real Time commands when the printer is busy at
the communication interface. A busy condition can be determined by bit 3 of the response to
DLE EOT 1. Other responses to DLE EOT n can determine the reason for a particular busy
condition.
Although the printer responds to Real Time commands when it is busy, it will place them into the
buffer behind any other data there, and flush them out in the order in which they were received.
When the printer is busy due simply to buffer full (that is, it can’t print data as fast as it can
receive it), then data continues to be processed out of the buffer at approximately print speed
and the Real Time commands will eventually get flushed out.
When the printer is busy due to an error condition, then data stops being processed of the buffer
until the condition clears one way or another. In either case, but more quickly in the case of an
error condition, the buffer can fill with Real Time commands.
To guard against this situation, the application must determine the cause of a busy condition and
take appropriate action or pace the Real Time commands to avoid filling the buffer. There is a
minimum of 256 bytes available in the printer’s buffer when it goes busy.
12.11.3 B
USY LINE AND FAULT CONDITIONS
If the printer is in error condition (cover is open, paper is exhausted…), the printer will go busy
immediately. Then it will stay busy and stop processing data out of the receive buffer until the
condition clears. It will respond to the Real Time commands as described below.

EAL TIME RECOVERY FROM FAULT

that prevents the printer from any printing function requires one of these commands to allow printing to
resume.

Notes
:
• This command will attempt recovery from any fault that prevents printing including jams and paper
out.
• Recovering from a print head over temperature condition is only accomplished by waiting until the
print head has returned to its operating temperature range.
• This command will be ignored until manual intervention has occurred to clear the fault condition. The
indication of manual intervention for clearing paper out, paper jams, cutter fault, consists of opening
and closing the clamshell.

RINT BAR CODE
Selects the bar code type and prints a bar code for the ASCII characters entered. If the width of
the bar code exceeds one line, the bar code is not printed.
There are two variations to this command. The first variation uses a NULL character to terminate
the string; the second uses a length byte at the beginning of the string to compensate for the
Code 128 bar code that can accept a NULL character as part of the data. With the second
variation the length of byte is specified at the beginning of the string.
Bar codes can be aligned left, center, or right using the Align Positions
command (1B 61).
The check digit is calculated for UPC and JAN (EAN) codes if it is not sent from the host
computer. Six-character zero-suppressed UPC-E tags are generated from full 11 or 12
characters sent from the host computer according to standard UPC-E rules. Start/Stop
characters are added for Code 39 if they are not included.

12.13 Flash firmware download commands
These commands are used to load firmware into the printer.
There are two ways to enter the download mode.
While the printer is running normally, send the command, “Switch to Flash Download Mode (1B
5B 7D)” to leave normal operation and enter the download mode.
If the Flash if found corrupted during Level 0 diagnostics the download mode is automatically
entered after the printer has reset.
The printer never goes directly from the download mode to normal printer operation. To return to
normal printer operation either the operator must turn the power off and then on to reboot or the
application must send a command to cancel download mode and reboot.
When each flash download command is received, the printer returns either ACK or NAK to the
host computer when each command is received:
ACK (hexadecimal 06)
Sent when the printer has received a host transmission and has completed the request
successfully.
NAK (hexadecimal 15)
Sent when a request is unsuccessful.
The commands are listed in numerical order according to their hexadecimal codes. Each
command is described and the hexadecimal, decimal, and ASCII codes are listed.
Communicates to the printer information downloaded from applications. Data is downloaded to
flash memory to query the state of the firmware, calculate the firmware CRC and other functions.
12.13.1 Firmware Download Sequence
By providing a set of low-level commands, great freedom of implementation is given to customer
application to customize the sequence to match its specific requirements.
Following is the description of a typical Firmware download sequence.
Only the main steps are mentioned.
Error checking and error recovery is not described:
1) Switch to Flash Download Mode
2) Check Flash Memory Size
3) Erase all Flash Memory sectors, except Boot Sector
4) Download Code to Active Flash Sector
4.1) Select Flash memory sector #n (each sector contains 64kbytes)
4.1.1) Program segment of N bytes
4.1.2) if more segments, loop back to 4.1.1)
4.2) if more sectors to program, loop back to 4.1)
5) Check Flash CRC
6) Reboot Printer

14 CLEANING YOUR PRINTER
Depending on the environment in which the printer is used, it can accumulate dust. Therefore it
is necessary to clean it periodically to maintain a good print quality. The cleaning period depends
on the environment and the usage of the printer, but the print head should be cleaned at least
once a year or up to one month in heavy duty applications.
Cleaning Instructions:
Unplug the printer. Never clean the head immediately after printing, the head may
be hot.
Open the cover, clean the heating dots line of the head with a cotton stick containing a
solvent alcohol (ethanol, methanol, or IPA) but do not touch the print head with your
fingers!
Allow the solvent to dry and close the cover.
