This printer according to the IBM Proprinter XL24E, IBM 2391 and EPSON ESC/P2
emulations supports the following printer commands.
P
Pr ri in nt t a an nd d L Li in ne e F Fe ee ed d E Ex xe ec cu ut ti io on n
CR
Prints all received data and the column counter is set to the left margin.
(IBM,EPSON)
ASCII Code CR
Hexadecimal Value 0D
Decimal Value 13
This code is a terminator code; when received, it causes any data in the buffer to be
printed out. The print head then moves logically to the left margin position. The
column counter is set to the left margin value and a line feed is inserted automatically
after the carriage return (see the automatic carriage return function in the printer
setup). The code resets the double width printing set by SO code.

10
ESC ]
Sets a reverse line feed. (IBM)
ASCII Code ESC ]
Hexadecimal Value 1B 5D
Decimal Value 27 93
This code is a terminator code; when received, it causes the current contents of the
print buffer to be printed out, before reversing the paper by one line at the current
vertical spacing. If no data precedes this command or if the preceding data consists of
spaces, the code causes only a reverse line feed to be performed. When the line counter
is equal to or less than the top of the form value, the ESC ] is ignored.
ESC 5
Sets an automatic line feed after a carriage return. (IBM)
ASCII Code ESC 5 n
Hexadecimal Value 1B 35 n
Decimal Value 27 53 n
If nis equal to 1, this command sets an automatic line feed on receiving of a CR code.
If nis equal to 0, this command cancels the automatic line feed.
nAutomatic line feed
0 Disabled
1 Enabled

11
ESC J
Advances paper n/180 inch. (EPSON)
ASCII Code ESC J n
Hexadecimal Value 1B 4A n
Decimal Value 27 74 n
Range 0 < n< 255
This is a terminator code; it therefore causes the current contents of the print buffer to
be printed out before performing a single line LF of n/180 inch. This command is
cancelled after the LF has been performed. The printing will restart after a line feed
from the column at which the command was sent.
LF
Line Feed. (IBM, EPSON)
ASCII Code LF
Hexadecimal Value 0A
Decimal Value 10
This is a terminator code; it therefore causes the current contents of the print buffer to
be printed out before advancing the paper by one line at the current vertical spacing.
If no data precedes the LF code, or if the preceding data consists of spaces, the code
causes only a line feed.
When the line counter reaches the last line of the form (defined by software or function
menu), the LF code causes a skip to the first line of the next form or ejects a cut sheet,
if loaded. This code cancels the double width printing set by the SO code. In IBM
mode, the column counter is set to the first column if the automatic carriage return is
selected. In EPSON mode, the column is always set to the first column.

12
F

ESC $
Sets the absolute printing position. (EPSON)
ASCII Code ESC & n1n2
Hexadecimal Value 1B 24 n1n2
Decimal Value 27 36 n1n2
Range 0 < n1< 255
0 < n2< 127
This command specifies the distance from the left margin where you want to print
subsequent characters. The default unit is 1/60 inch. The distance is in number of dots
and must be calculated using the following formula:
Margin distance = n1+ (n2x 256) x 1/60” + (left margin)
Where n2is equal to:
1
[(horizontal position) – (left margin position)] x(defined unit )
INIT
256
Where n1is equal to:
1
[(horizontal position) – (left margin position)] x(defined unit )
MOD
256
If the selected position is outside the current right margin, the sequence will be
ignored.

13
ESC (C
Sets page length in defined unit. (EPSON)
ASCII Code ESC ( C n1n2d1d2
Hexadecimal Value 1B 28 43 n1n2d1d2
Decimal Value 27 40 67 n1n2d1d2
Range n1= 2
n2= 0
0 < ((d2x 256) + d1) x (defined unit) < 22
This command sets the page length in the specified number of units (the default unit
is 1/360 inch), previously defined with the ESC ( U command according to the
following formula:
Page length = ((d2x 256) + d1) x (defined unit)
Where d2is equal to:
1
(page length) x(defined unit )
INIT
256
Where d1is equal to:
1
(page length) x(defined unit )
MOD
256
Set the page length before paper is loaded or when the print position is at the top-of-
form position. Otherwise, the current print position becomes the top-of-form position.
Setting the page length cancels the top and bottom-margin settings. If the defined unit
is changed it does not affect the current page-length setting.

14
ESC ( c
Sets Page Format. (EPSON)
ASCII Code ESC ( c n1n2t1t2 b1b2
Hexadecimal Value 1B 28 63 n1n2t1t2 b1b2
Decimal Value 27 40 99 n1n2t1t2 b1b2
Range n1= 4
n2= 0
((t2x 256) + t1) < ((b2x 256) + b1)
(defined unit) x ((b2x 256) + b1) < 22
This command sets the top and bottom margins in the defined units, set with the ESC
( U command, according to the following formulas:
Top margin = ((t2x 256) + t1) x (defined unit)
Where t2is equal to:
1
(top margin) x(defined unit )
INIT
256
Where t1is equal to:
1
(top margin) x(defined unit )
MOD
256

15
Bottom margin = ((b2x 256) + b1) x (defined unit)
Where b2is equal to:
1
(bottom margin) x(defined unit )
INIT
256
Where b1is equal to:
1
(bottom margin) x(defined unit )
MOD
256
Send this command before paper is loaded or when paper is at the top-of-form position.
Otherwise the current print position becomes the top-margin position. Measure both
top and bottom margins from the top edge of the page. The baseline for printing
characters on the first line is 20/180 inch below the top-margin position.
This command cancels any previous top and bottom-margin settings.

16
ESC ( U
Sets units. (EPSON)
ASCII Code ESC ( U n1n2d
Hexadecimal Value 1B 28 55 n1n2d
Decimal Value 27 40 85 n1n2d
Range n1= 1
n2= 0
d= 10, 20, 30, 40, 50,60
This command sets the unit to m/3600 inch. The printer uses this unit when moving
the print position, setting the page length and setting the top and bottom margins
with the following commands (the default units varies depending on the command and
print quality):
Commands Default Unit
ESC ( V 1/360 inch
ESC ( v 1/360 inch
ESC ( C 1/360 inch
ESC ( c 1/360 inch
ESC \ (LQ mode) 1/180 inch
ESC \ (Draft mode) 1/120 inch
ESC $ 1/60 inch

17
ESC ( V
Sets absolute vertical print position. (EPSON)
ASCII Code ESC ( V n1n2d1d2
Hexadecimal Value 1B 28 56 n1n2d1d2
Decimal Value 27 40 86 n1n2d1d2
Range n1= 2
n2= 0
0 < d1< 255
0 < d2< 127
This command moves the vertical print position to the position specified by the
following formula:
Vertical position = (d2x 256)+d1) x (defined unit) + (top-margin position)
Where d2is equal to:
1
[(vertical position) –(top margin position)] x(defined unit )
INIT
256
Where d1is equal to:
1
[(vertical position) –(top margin position)] x(defined unit )
MOD
256

18
The default unit is 1/360 inch. The new position is measured in defined units from the
current top-margin position. Moving the print position below the bottom-margin
position moves the vertical print position to the top-margin position on the next page
ejects a cut sheet, if loaded.
The printer ignores this command if the command would move the print position more
than 179/360 inch in the negative direction or if the command would move the print
position in the negative direction after a graphics command is sent on the current line
or above the point where graphics have previously been printed.
ESC ( v
Sets relative vertical print position. (EPSON)
ASCII Code ESC ( v n1n2d1d2
Hexadecimal Value 1B 28 76 n1n2d1d2
Decimal Value 27 40 118 n1n2d1d2
Range n1= 2
n2= 0
0 < d1< 255
0 < d2< 127
This command moves the vertical print position up or down from the current position,
as specified by the following formula
Vertical position = (d2x 256)+d1) x (defined unit) + (current position)
For positive (down) movement:
Where d2is equal to:
1
[(vertical position) –(current position)] x(defined unit )
INIT
256
