SAFETY PRECAUTIONS AND INSTALLATION
DPT 282 PLM
SAFETY PRECAUTIONS
Read and keep the following instructions.
•∙Observe all warnings and follow all instructions attached to the
printer.
•∙Before cleaning the printer, disconnect the feed cable.
•∙Clean the printer with a damp cloth. Do not use liquid or spray
products.
•∙Do not operate the printer near to water.
•∙Do not place the printer on unsteady surfaces. It could fall and
get seriously damaged.
•∙Do not place the printer on soft surfaces or in poorly ventilated
environments.
•∙Position the printer in such a way as to ensure that the cables
connected to it will not be damaged.
•∙Use the type of electricity supply marked on the printer label.
In the event of uncertainty, contact the seller.
•∙Ensure that the printer’s electricity supply is grounded and that
it is protected by a differential switch.
•∙If the printer is fed through an extension lead, ensure that the
total absorption of the equipment connected to it does not exceed
the maximum admissible current for that type of extension and
that it does not, in any event, exceed 15 amperes.
•∙Do not obstruct the vents.
•∙Do not put objects of any kind inside the printer as they could
cause a short circuit or damage parts which could affect its
performance.
•∙Do not spill liquids on the printer.
•∙Do not carry out technical operations on the printer with the
exception of the scheduled maintenance operations specifically
indicated in the user’s manual.
•∙Disconnect the printer from the electricity supply and have it
repaired by a specialized technician should any of the following
conditions occur:
A. The feed connector has been damaged.
B. liquid has penetrated to the inside of the printer;
C. The printer has been exposed to rain or water;
D. The printer is not operating normally despite the instructions in
the user’s manual having been followed.
E. The printer has been dropped and its case damaged.
F. The performance of the printer is poor.
G. The printer does not work.
INSTALLATION PROCEDURE
•Place the printer near the computer or the working station so that
the connecting cable arrives easily;
•Before to connect the printer to the supply, check if the voltage
and the feeding frequency correspond to those showed on the
characteristics' label, the feeding system has the earthing and the
switch is in OFF;
•It's necessary to have near the printer a sufficient place for a
suitable space for ventilation and for standard printing operation
and maintenance.

1.3 FRONT PANEL
The FEED and PRINT keys and a green indicator light are on the front panel.
•Pressing the FEED key, printer carries out paper feed which can be used to insert paper in
printing mechanism. Pressing the key once gives double paper feed. During the switch on
phase, if you hold the FEED key down the printer performs the FONT TEST.
•During the switch on phase, if you hold down PRINT, the printer carries out the GRAPHIC
TEST with programmable logo.
•During the switch on phase, if you hold down the PRINT and FEED key, the printer goes in
Print Setup. After printer setup report, the printer waits a button pressed, or characters from
serial port ; every 10 chars, prints hex values and ASCII codes (if characters are underline,
the receive buffer is in the full state), see Hexadecimal Dump.
With FEED button, the printer skips setup mode and ends Hexadecimal Dump function.
With PRINT button, the printer goes into the parameters setting mode. The variables are:
•Printer ID : 1 - 63.
•Printer emulation : ESC/POS, CUSTOM DPT24 or CUSTOM DPT42.
•Baud Rate : 1200, 2400.
•Autofeed : CR disabled or CR enabled.
•Print mode : Normal or Reverse.
•Height mode : x1, x2 or x4.

kindicates the total number of horizontal tab positions to be set.
[Notes] •The horizontal tab position is stored as a value of [character width ×n]
measured from the beginning of the line. The character width includes the
rigth-side character spacing, and double-width characters are set width
twice the width of normal character.
•This command cancel the previous horizontal tab setting.
•When setting n= 8, the print position is moved to column 9 by sending
HT.
•Up to 32 tab position ( k= 32) can be set. Data exceeding 32 tab
positions is processed has normal data.
•Transmit [ n] kin ascending order and place a NUL code 0 at the end.
•When [ n] kis less than or equal to the preceding value [ n] k-1, tab
setting is finished and the following data is processed as normal data.
•ESC D NUL cancels all horizontal tab position.
•The previously specified horizontal tab position do not change, even if the
character width changes.
[Default] The default tab positions are at intervals of 8 characters ( columns 9, 17,
25, ...) for Font A when the right-side character spacing is 0.

Hex 1B 5C nL nH
Decimal 2792nLnH
[Range] 0 ≤nL ≤255
0 ≤nH ≤255
[Description] Sets the print starting position based on the current position by using the
horizontal or vertical motion unit.
•This command sets the distance from the current position to
[( nL + nH ×256) ×( horizontal or vertical motion unit)].
[Notes] •Any setting that exceeds the printable area is ignored.
•When the starting position is specified by N motion unit to the right :
nL + nH ×256 = N
When the starting position is specified by N motion unit to the left (negative
direction), use the complement of 65536 :
nL + nH ×256 = 65536 - N
•If setting exceeds printing area width, left or right margin is set to default
value.
•The horizzontal and vertical motion unit are specified by GS P.
•The GS P command can change the horizontal (and vertical) motion unit.
However, the value cannot be less than the minimum horizontal movement
amount.
•In standard mode, the horizontal motion unit is used.
