1 General
The MTP-1500 series of modular thermal printers is designed specifically for the high performance, size and durability
requirements of cut and drop applications. The compact size and high performance characteristics, coupled with its
rugged design also make it ideal for the kiosk environment.
Four models make up the MTP-1500 Series:
· MTP-1530-SF - 80 mm (3.15 in) paper width , Full Cut . (Part # 901033-0006)
· MTP-1530 -SP - 80 mm (3.15 in) paper width , Partial Cut. (Part # 901034-0006)
· MTP-1532 -SF – 82.5 mm (3.25 in) paper width , Full Cut. (Part # 901033-0010)
· MTP-1532 -SP – 82.5 mm (3.25 in) paper width , Partial Cut. (Part # 901034-0010)
1.1 Definitions
1.1.1 Standard Mode versus Page Mode
Standard mode means printing data as it is received like most serial mode printers. If data is not received fast enough
to keep the printer busy, the printer will print data it has received and then stop and wait for more data to be received
so it can print a little more. This is the most commonly used mode of operation but anytime the printer has to stop and
then restart, there is a possibility of reduced print quality.
· Page mode means that all the data to be printed on a page is received before printing begins so once the
printing process starts, an entire page is printed at full speed.
· Most commands and parameters are the same for both standard mode and page mode but the ESC SP, ESC 2,
and ESC 3 are set independently in standard mode and page mode, See section 4.2 Control Codes and Control
Sequences List .
· Some commands apply only to page mode and some commands are ignored in page mode.
See Table xxx +++ add bookmark to COMMAND LIST table.
· Ladder bar codes can be printed only in page mode.
1.1.2 Hex Dump Mode
This function is sometimes useful for diagnosis of application programs when the printer does not perform as
expected. In hex dump mode, the printer prints the hexadecimal code for each character received rather than
processing the data as printable text and as control commands. The exception is that DLE EOT (real time STATUS
request) and DLE ENQ (Real time request to printer) are executed as received even in hex dump mode. The
hexadecimal notation is printed at 10 characters per line on the left side of the page and the printable characters (when
possible) are printed on the right side of the page. Control codes print as periods on the right side section of the
printout to help locate specific areas of the message to see what codes were actually received by the printer. After all
data has been sent to the printer, pressing the paper feed button will flush the buffer and print the last line of data
received.
Hex dump mode is initiated in any of three ways:
1) Open the platen, hold the paper feed button down, turn on power, then close the platen and release the paper
feed button.
2) Set DIP switch DPSW2 position 5 ON and then turn on power.
3) Send the appropriate GS ( A command. On entering hex dump mode, the printer prints a 4 line header
“Hexadecimal Dump”, a blank line, “To terminate hexadecimal dump”, “press FEED three times.”
Hex dump mode is terminated by
1) pressing the paper feed button three times in quick succession or
2) by turning DIP switch DPSW2 position 5 OFF and turning power back on.

1.1.3 Explanation of Terms used throughout this manual
Receive buffer – Receives data from the host and stores the data temporarily until it can be processed to the print
buffer or processed as otherwise required.
Print buffer – Stores the image data to be printed.
Start of line – There is no print data in the print buffer and the print position is not specified by ESC $ or ESC \. Many
commands are effective only at the start of line.
Printable area – In standard mode the length in the horizontal direction is: 80 mm (640 dots per line/8 dots per mm)
for the 82.5 mm paper width version, 72 mm (576 dots per line/8 dots per mm) for the 80 mm paper width version. In
page mode the length in the horizontal direction is: 80 mm (640 dots per line/8 dots per mm) for the 82.5 mm paper
width version, 72 mm (576 dots per line/8 dots per mm) for the 80 mm paper width version. In page mode the length in
the vertical direction is: 83 mm (664 dots per line/8 dots per mm) for the 82.5 mm paper width version, 92 mm (738
dots per line/8 dots per mm) for the 80 mm paper width version.

2 Operator Instructions
2.1 Unpacking and Inspection
Carefully unpack and inspect your MTP-1500 for any damage that may have occurred in transit. Should any damage
have occurred, notify Telpar, Inc., save the shipping carton and packing materials , and file a damage claim with the
carrier. Specify the nature and the extent of the damage. Before installing or operating the printer, check the following:
 Printer mechanism and paper path are clear of all packing materials or other foreign matter.
 Paper is installed. DO NOT OPERATE the printer without paper. Refer to Section 2.2 - Paper Loading page 15
for paper loading instructions.
2.2 Paper Loading
2.2.1 Side-Loading Roll
The MTP-1500 series printer is configured as a side-loading printer . Slide roll of paper over spindle with paper fed
under the bottom toward paper slot (front of unit).
To load paper , turn on the power and feed the straight edge of the paper into the paper guide. AUTOLOAD will
automatic load paper once it is fed into the paper guide. Once paper has been initially loaded, the paper feed button
may be used. Ensure that the paper is installed correctly and feeding properly with the thermal side facing up.
2.2.2 Black Mark Sensors Load
The MTP-1500 series printer may be used with the optional Black Mark Sensor. This requires the use of a pre-printed
Top of Form (TOF) Mark or Black Mark on the form. Dip switch SW1 position 1 must be set to the ON position to
enable black mark operation.
If DIP switch DSW1 position 1 is turned on to enable the Black Mark sensor when the printer is loaded with plain
paper, at Power On the printer will feed about 17.5 inches of paper looking for a Black Mark and then go to an error
mode since it did not find a Black Mark.
To load paper , turn on the power and feed the straight edge of the paper into the paper guide. Ensure that the paper
is installed correctly and feeding properly with the thermal side facing up.
If using perforated paper, the perforation should be fed at least 1.27 mm (0.05 in) past the cut line to avoid a jam at the
cutter. The black mark may extend across the full width of the paper. (TBD)
See Figure 4 Black Mark Specifications
See section 4.3.5 Top of Form Commands

Page 14 of 64
NEED NEW DRAWING
Figure 4 Black Mark Specifications
See section 4.3.5 - Top of Form Commands for additional information.
2.3 Paper Jam
In the event of a paper jam condition do not force paper into the unit, or try to pry the paper out of the unit, this may
damage the thermal print mechanism . Caution should be exercised when working next to the cutter mechanism , the
blades are sharp and may cause serious injury.
To release paper:
 Turn off power to the printer.
 Push the Head Open lever to the down position.
 (See Figure 6 - MTP-1500 with Cutter Mechanism open ) Paper can be removed at this time. Once paper is
cleared from the mechanism, return the Head Open lever to the up position.
2.3.1 Head Open Lever
The Head Open lever is located at the left front of the printer mechanism. The up position is ready to print. The down
position lifts the print head off of the platen roller for manually inserting paper or for clearing a paper jam. The down
(head open) position signals the microprocessor that the head is open so that no printing will occur.

backward direction relative to the cutting position. In this case, the maximum backward feed length is 14 mm (112 *
0.125mm).
4.1.2 LEDs and Error Indication
Three LEDs (D3, D5, and D6) are located above Dip switch DSW1.

Page 18 of 64
D3 is the green POWER LED, ON means power is stable and the printer is ready for operation. OFF means power
in not stable.
D5 is a red PAPER OUT LED, OFF means paper is installed and the printer is ready for operation. ON means
there is no paper installed in the printer mechanism (or the paper low sensor if selected). The PAPER OUT LED blinks
steadily to specify that self test has finished the first part of printing and that the user can press the PAPER FEED
button to print the “barber pole” character print part of the self test. The PAPER OUT LED also blinks steadily to
specify that a MACRO is waiting for the user to press the PAPER FEED button to continue it’s execution (macro stand-
by mode).
D6 is a red ERROR LED. OFF means there are no errors and the printer is ready for operation. ON indicates the
printer is OFF LINE (except during paper feeding using the FEED button, during self-test printing, and in the error
state). The ERROR LED blinks a defined pattern every 5.12 seconds to notify the user of various error conditions.
When the LED is normally OFF and blinks ON, an error is indicated which may be recoverable. . When the LED is
normally ON and blinks OFF, an error is indicated which in not recoverable. For any error that is not recoverable,
power should be turned off as soon as possible.
