interface) and when the printer is ready to receive data.

• During the self-test.

• When the cover is open.

• During paper feeding using the paper feed button.

• When the printer stops printing due to a paper-end (in cases when
an empty paper supply is detected by either paper roll end detector or
the paper roll near-end detector with a printing halt feature by
ESC c4).

• During macro executing stand by status.

• When a temporary abnormality occurs in the power supply voltage.

• When an error has occurred.

Print Commands

The WTP series supports the following commands for printing characters and advancing
paper.

HT

[Name] Horizontal tab

[Format] ASCII HT
Hex 09
Decimal 9

[Description] Moves the print position to the next tab position.

[Details] ·This command is ignored unless the next tab position has been set.

·If the next horizontal tab position exceeds the printing area, the printer
sets the printing position to [Printing area width + 1].

·Horizontal tab positions are set using “ ESC D” .

·If this command is received when the printing position is at [printing area
width +1], the printer executes print buffer-full printing of the current
line and horizontal tab processing from the beginning of the next line.

·The default setting of the horizontal tab position for the paper roll is font
A
(12 x 24) every 8th character (9th, 17th, 25th, … column).

[Reference] ESC D

LF

[Name] Print and line feed

[Format] ASCII LF
Hex 0A
Decimal 10

[Description] ·Prints the data in the print buffer and feeds one line based on the current

line spacing.

[Details] ·This command sets the print position to the beginning of the line.

[Reference] ESC 2, ESC 3

TITLE : RP-300/310

Page -22 -

CR

[Name] Print and carriage return.

[Format] ASCII CR
Hex 0D
Decimal 13

[Description] When automatic line feed is enabled, this command functions the same

as LF; when automatic line feed is disabled, this command is ignored.

[Details] ·Sets the print starting position to the beginning of the line.

·The automatic line feed is ignored.

[Reference] LF

FF

[Name] Print and return to standard mode in page mode.

[Format] ASCII FF
Hex 0C
Decimal 12

[Description] Prints the data in the print buffer and returns to standard mode.

[Details] ·The buffer data is deleted after being printed.

·The printing area set by ESC W is reset to the default setting.

·The printer does not execute paper cutting.

·This command sets the print position to the beginning of the line.

·This command is enabled only in page mode.

[Reference] ESC FF, ESC L, ESC S

CAN

[Name] Cancel print data in page mode

[Format] ASCII CAN
Hex 18
Decimal 24

TITLE : RP-300/310

Page -23 -

[Description] In page mode, delete all the print data in the current printable area.

[Details] ·This command is enabled only in page mode.

·If data that existed in the previously specified printable area also exists in
the currently specified printable area, it is deleted.

[Reference] ESC L, ESC W

DLE EOT n

[Name] Real-time status transmission.

[Format] ASCII DLE EOT

n

Hex 10 04

n

Decimal 16 4

n

[Range] 1≤n≤4

[Description] Transmits the selected printer status specified by n in real-time,

according to the following parameters:

n

=1 : Transmit printer status

n

=2 : Transmit off-line status

n

=3 : Transmit error status

n

=4 : Transmit paper roll sensor status

[Details] ·The printer transmits the current status. Each status is represented by

one-byte data.

·The printer transmits the status without confirming whether the host

computer can receive data.

·The printer executes this command upon receiving it.

·This command is executed even when the printer is offline, the receive

buffer is full, or there is an error status.

·When Auto Status Back (ASB) is enabled using the GS a command, the

status transmitted by the DLE EOT command and the ASB status must
be differentiated.

·Even though the printer is not selected using ESC = (select peripheral
device), this command is effective.

[Notes] ·The status is transmitted whenever the data sequence of

<10>H<04>H<n> (1≤ n≤ 4) is received.

Example :
In ESC *

m nL nH d1…dk

d1=<10>H, d2=<04>H, d3=<01>H

·This command should not be used within the data sequence of another
command that consists of 2 or more bytes.

Example :
If you attempt to transmit ESC 3

n

to the printer, but DTR (DSR for

the host computer) goes to MARK before

n

is transmitted and then

DLE EOT 3 interrupts before

n

is received, the code <10> H for DLE

due to a circuit failure (e.g. wire break) occurs, it is impossible to recover.

DLE ENQ n

[Name] Real-time request to printer

[Format] ASCII DLE ENQ n
Hex 10 05 n
Decimal 16 5 n
[Range] 1≤n≤2

[Description] Responds to a request from the host computer.

n

specifies the requests as follows:

n Request
1 Recover from an error and restart printing from the line where the error occurred
2 Recover from an error aft clearing the receive and print buffers

[Details] ·When the printer is disabled with ESC = (Select peripheral device), this

command is effective.

·This command is effective only when an auto-cutter error occurs.

·The printer starts processing data upon receiving this command.

·This command is executed even when the printer is offline, the receive
buffer is full, or there is an error status with a serial interface model.

·The status is also transmitted whenever the data sequence of
<10>H<05>H< n> (1≤ n≤ 2) is received.

Example:

In ESC * ** * m

nL nH dk, d1 = <10>H, d2 = <05>H, d3 = <01>H

·This command should not be contained within another command that
consists of two or more bytes.

Example:

If you attempt to transmit ESC 3 n to the printer, but DTR (DSR
for the host computer) goes to MARK before n is transmitted, and
DLE ENQ 2 interrupts before n is received, the code <10>H for
DLE ENQ 2 is processed as the code for ESC 3 <10>H.

DLE DC4

n m t

[Name] Generate pulse at real-time

[Format] ASCII DLE DC4 n m t
Hex 10 14 n m t
Decimal 16 20 n m t

[Range] n=1

m=0,1
1≤ t≤ 8

[Description] Outputs the pulse specified by t to connector pin m as follows:

m Connector pin
0 Drawer kick-out connector pin 2.
1 Drawer kick-out connector pin 5.

The pulse ON time is [ t x 100 ms] and the OFF time is [ t x 100 ms].

[Details] ·When the printer is in an error status when this command is processed,

this command is ignored.

·When the pulse is output to the connector pin specified while ESC p or
DEL DC4 is executed while this command is processed, this command is
ignored.

·The printer executes this command upon receiving it.

·This command is executed even when the printer is off-line, the receive
buffer is full, or there is an error status.

·If print data includes the same character strings as this command, the
printer performs the same operation specified by this command. The user
must consider this.

·This command should not be used within the data sequence of another
command that consists of 2 or more bytes.

·This command is effective even when the printer is disabled with ESC =
(Select peripheral device).
