Specification
(STANDARD)
General Description
Application
These specifications apply to TM-U295(Standard Specification)(RS-232 Serial Interface
Specification) or to TM-U295P (IEEE 1284 Bidirectional Parallel Interface Specification).
Features
The TM-U295 is terminal slip printer which uses a 7-pin shuttle dot printing method, and
provides the different modes, standard and page (*).
The printer has the following features:
ùProgrammable page length.
ùProgrammable print starting position.
ùMultiple character sizes (standard, double-width, double-height, and quadruple).
ùCharacter directions: 4
ùInternational character set selection.
ùForward and backward paper feeding.
ùCommand protocol based on the ESC/POSTM standard.
ùProgrammable paper feed amount.
ùPaper eject function.
ùTop Of Form (TOF) and Bottom Of Form (BOF) sensors.
ùData reception during printing (improved throughput and less waiting time for the host
computer).
ù512 byte printer buffer memory.
ùCompact, space efficient design.
ùDrawer kick-out function.
ùAutomatic Status Back (ASB) function to automatically send printer status changes.
ùEither RS-232 serial interface or 1284 bidirectional parallel interface should be selectable
when the product is shipped from the factory.
*In page mode, the print data is buffered within a specified printing area in the memory.
After all the data has been buffered in the specified printing area, it is all printed at one
time.

b) Combination of normal paper and pressure sensitive paper:
3 sheets maximum (1 original and 2 copies) (0.09 to 0.35 mm (.0035 to .0138"))
Backing paper: 0.07 to 0.20 mm (.0028 to .0079")
Copy and original paper: 0.04 to 0.07 mm (.0016 to .0028")
Carbon copy paper: Approximately 0.035 mm (.0014")
Example: 1 original and 2 copies
Original: 0.04 mm (.0016") (0.04 mm
´ 1 sheet)
Carbon copy paper: 0.035 mm (.0014") (0.035 mm
´ 2 sheets)
Copy: 0.04 mm (.0016") (0.04 mm
´ 1 sheet)
Backing paper: 0.07 mm (.0028") (0.07 mm
´ 1 sheet)
Total thickness: 0.22 mm (.0087")
5) Copy capability and ambient temperature for printing
Copying capability is influenced by the ambient temperature. Printing must be performed under the
conditions, described in Table 1.4.1.

6) Notes on using slip paper
ù Slip paper should be flat, without curls, wrinkles, or camber, especially at the paper edges.
Otherwise, the paper may become ink stained.
ù When using multiply-ply carbon copy paper, it should be flat and the glue area should be as small as
possible.
ù Glue area should be located at the top or left edge of the slip paper.
ù Since TOF and BOF sensors are optical sensors, paper having holes at the sensor positions or
translucent paper should not be used normally. When using these papers, be sure to disable the
paper sensors by ESCc4 .
ù When using slip paper of 80 mm (3.15") long or less, load the paper so that it is fed straight.

7) Printing position
Figure 1.4.1 Printing Position
NOTES: 1. The mechanical form stopper is adjustable in the range 26.5 to 36.5 mm (1.04 to 1.44").
2. The TOF and BOF sensors are fixed and cannot be adjusted.
3. After slip paper is set at the mechanical form stopper, the top margin can be shortened up
to 21.2 mm (.83") by feeding the paper backwards (ejection feeding).
4. When ejection feeding is not performed after printing, printing can be performed up to the
position at which the paper edge is no longer held by the paper feed roller (13.8 mm (.54")
from the paper edge).
5. When ejection feeding is performed after printing, the paper can be fed forward up to 11.8
mm (.46") (28 dots) after the bottom edge is detected.
