Notes on slip paper
❏ Slip paper should be flat, without curls, wrinkles, or camber,
especially at the paper edges. Otherwise, the paper may
become ink stained.
❏ When using multiply-ply carbon copy paper, it should be flat
and the glue area should be as small as possible.
❏ Glue area should be located at the top or left edge of the slip
paper.
❏ Since TOF and BOF sensors are optical sensors, paper having
holes at the sensor positions or translucent paper should not be
used normallly. When using these papers, be sure to disable the
paper sensors by ESC c 4.
❏ When using slip paper of 80 mm (3.15”) long or less, load the
paper so that it is fed straight.
❏ Use thinner paper (N30 or equivalent) between the top and
bottom sheets of multi-ply paper. If thick paper is used, the
copy capability is lowered.

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.

➀When standard mode is selected:
[Description] Prints the data in print buffer and ejects the sheet.
[Notes]
• When the eject length has been set by ESC C, the printer ejects the
sheet based on the current eject length. Otherwise, the printer
ejects the sheet completely. If a paper out is detected during
ejection, the printer stops ejecting the sheet even if the specified
amount of paper has not been ejected.
• The ejecting direction is specified by ESC F.

[Range]
1≤ n ≤ 3, n = 5
[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 = 5: Transmit slip paper status
[Notes]
• The printer executes this command upon receiving it.
• When transmitting status, the printer transmits only 1 byte
without confirming the condition of the DSR signal.
• With the serial interface model, this command is executed even in
off-line or receive buffer-full state. However, with the parallel
interface model, this command is not executed in off-line or
receive buffer-full state because the printer is busy and unable to
receive this command from the host.
• The status is transmitted whenever the data sequence of
<10>H<04>H<n> (1 ≤ n ≤ 3, n = 5) is received even if it appears as
part of another command. For example,
In ESC ✻ m n L n H [d] n L+256✕n H, d1=<10>H, d2=<04>H,
d3=<1>H
Commands 5-3
• This command should not be used within the data sequence of
another command that consists of 2 or more bytes. For 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 EOT 3 is processed as the code for ESC 3
<10>H.
• 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.
• If the n is out of the specified range, the printer ignores this
command.

• The nL and nH indicate the number of dots of the bit image in the
horizontal direction. The number of dots is calculated by nL + nH
✕ 256.
• If the bit-image data input exceeds the number of dots to be
printed on a line, the excess data is ignored.
• d indicates the bit-image data. Set a corresponding bit to 1 to print
a dot or to 0 to not print a dot.
• If the values of m and nH are out of the specified range, the
following data is processed as normal data.
• After printing a bit image, the printer returns to normal data
processing mode.
• In page mode, double density bit image data is not available.

• This command cancels the previous horizontal tab settings.
• n = column number to be set - 1. When setting n = 8, the print
position is moved to column 9 by sending HT.
• k indicates the total number of horizontal tab positions to be set.
• The horizontal tab position is stored as an absolute value of
[character width ✕ n] measured from the beginning of the line. The
character width includes the right-side character spacing, and
double-width characters are set with twice the width of normal
characters. Also, when character is enlarged in the horizontal
direction in page mode, the horizontal position is set as the same
way as in standard mode.
• Transmit [n]k in ascending order and place a NUL code 0 at the
end.
• ESC D NUL cancels all horizontal tab positions. An HT received
after clearing tabs is ignored.
5-14 Commands
[Notes]
[Default]
• Up to 32 tab positions (k = 32) can be set. Data exceeding 32 tab
positions is processed as normal data.
• When [n]k is less than or equal to the preceding value [n]k-1, tab
setting is finished and the following data is processed as normal
data.
• When [n]k exceeds the number of characters printable on one line,
the tab position set is equal to the maximum printable column
plus 1.
• The previously specified horizontal tab positions do not change,
even if the character width changes.
• The right-side spacing is set independently in standard and page
modes. The horizontal tab setting is set by using amount of the
right-side spacing of the mode used.
The default tab positions are at intervals of 8 characters (columns 9,

• This command is enabled only when input at the beginning of a
line.
• This command is available only in standard mode.
• After printing by FF is completed, the printer returns to standard
mode.
• This command sets the position where data is buffered to the
position specified by ESC T within the printable area defined by
ESC W.
• In page mode, the printer buffer receives data in the printable area
specified by ESC W and prints the data collectively upon receipt
of FF command. The print and line feed commands, such as LF,
ESC J, ESC K, ESC d, and ESC e, only move the print start
position from which subsequent data is buffered and do not
perform actual printing.
• In page mode, the printer porcesses data referring to normal dot.
Therefore, be careful when using half dot in standard mode.
• Only character fonts with normal dot configuration are available.
• This command switches the settings for the following commands
(in which the values can be set independently in standard mode
and page mode) to those for page mode:
Set character spacing: ESC SP
Select 1/6-inch line spacing: ESC 2
Set line spacing: ESC 3

maximum printing area automatically, depending on the values
from xL to dyH.
• If (horizontal print starting position + horizontal length) or
(vertical print starting position + vertical length) is outside the
printable area, the maximum printing area is set to the printable
area.
• When the print data is buffered in the specified printing area, the
length of the printing area in both the horizontal and vertical
direction should be 8 dots or more.
• The printing area should accommodate to the size of the print
sheet.
• When the starting point (x0, y0) exceeds the printing area, this
command is ignored.

5-24 Commands
• When the connector is not used, the value of bit 0 is always 1.
• When DTR/DSR control is selected, the printer transmits only 1
byte after confirming that the host is ready to receive data (DSR
signal is SPACE). If the host computer is not ready to receive data
(DSR signal is MARK), the printer keeps waiting until the host is
ready. When XON/XOFF control is selected, the printer transmits
only 1 byte without checking the DSR signal.
• This command is executed when the data is processed in the
receive buffer. Therefore, there may be a time lag between
receiving the command and transmitting the status, depending on
the receive buffer status.
• When Auto Status Back (ASB) is enabled using GS a, the status
transmitted by ESC u and the ASB status must be differentiated.
• If n is out of the specified range, the printer ignores this command.

[Notes]
• If n = 0, ASB is disabled.
• ASB is enabled if only one status is selected. The printer
automatically transmits a status of four bytes whenever the status
changes.
• If ASB is enabled while processing this command, the current
status is transmitted with no regulations.
• When transmitting a status, the printer transmits only four bytes
without confirming the condition of the DSR signal.
• Four bytes of status data must be consecutive, except for XOFF
code.
• This command is executed when the data in the receive buffer is
developed. Therefore, there may be a time lag between receiving
this command and transmitting the status, depending on the
receive buffer status.
• When the printer is disabled by ESC =, this command is disabled
but ASB is not disabled.
• When using ESC u, ESC v, GS I or DLE EOT, the status
transmitted by this command, the ASB information, and the status
transmitted by another commands must be differentiated.

Bit 1:
• Becomes On (slip printing possible) when slip paper is detected
and becomes Off (slip printing is not possible) when slip
ejection starts or time-out.
• When the printer goes to the slip wait status, bit 5 and 6 of the
third byte are On (no paper) and bit 1 of the forth byte is On
(slip printing is not possible).
• When paper-end stop is disabled by ESC c 4, bit 1 does not
become On (slip printing is not possible) even if no printing
area remains.
• When the release button is pressed during slip printing, bit 1
becomes On (slip printing is not possible).

[Notes]
5-32 Commands
• When DTR/DSR control is selected, the printer transmits only 1
byte after confirming the host is ready to receive data (DSR signal
is SPACE). If the host computer is not ready to receive data (DSR
signal is MARK), the printer waits until the host is ready. When
XON/XOFF control is selected, the printer transmits only 1 byte
without confirming the condition of the DSR signal.
• This command is executed when the data in the receive buffer is
developed. Therefore, there may be a time lag between receiving
this command and transmitting the status, depending on the
receive buffer status.
• When Auto Status Back (ASB) is enabled using GS a, the status
transmitted by GS r and the ASB status must be differentiated.
• If the value of n is out of the specified range, the printer ignores
this command.
• The status types to be transmitted are shown below:
