EEPPSSOONN//IIBBMM MMooddee

The following printer commands are supported b y this printer according to the IBM Proprinter
XL24-XL24 AGM, IBM 2391+ and EPSON LQ Series.

PPrriinntt aanndd LLiinnee FFeeeedd EExxeeccuuttiioonn

CR

Prints all received data and the column counter is set to the left margin.

ASCII Code CR
Hexadecimal Value 0D
Decimal Value 13

This code is a terminator code; when receiv ed, it causes any data i n 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.

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 receiv ed, 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.

8

ESC 5

Sets an automatic line feed after a carriage return. (IBM)

ASCII Code ESC 5 n
Hexadecimal Value 1B 35
Decimal Value 27 53

n

n

If n is equal to 1, this command sets an automatic line feed on receiving of a CR code. If n is
equal to 0, this command cancels the automatic line feed.

n Automatic line feed
0 Disabled
1 Enabled

ESC J

Advances paper n/180 inch. (EPSON and IBMXL24AGM)
Advances paper n/216 inch. (IBMXL24 and 2391)

ASCII Code ESC J n
Hexadecimal Value 1B 4A
Decimal Value 27 74
Range 1 <

This is a terminator code; it therefore causes the current contents of the print buffer to be
printed out before performing a single line feed of n/180 or n/216 inch. This command is
cancelled after the line feed has been performed. The printing will restart after a line feed from
the column at which the command was sent.

n

n

n < 255

9

LF

Line Feed.

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. 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.

ASCII Code ESC &
Hexadecimal Value 1B 24
Decimal Value 27 36

This command specifies the distance from the left margin where you want to print subsequent
characters. The distance is in number of dots and must be calculated using the following
formula:

Margin distance = n

+ (n

1

x 256)

2

where n2 is the integer result of the number of dots divided by 256 and the n1 is the remainder. 1 dot =
1/60 inch. If the selected pos ition is outside the cur rent right margin, the se quence will be ignored.

ASCII Code ESC \
Hexadecimal Value 1B 5C
Decimal Value 27 92
Range 0 <

This command specifies the distance between the current print head position and the position
where you want to print subsequent characters (relative position). The distance is in number of
dots and must be calculated using the following formula:

Current position distance = n
where n2 is the integer result of the number of dots divided by 256 and the n1 is the remainder.

The unit of the dots is 1/120 inch for Draft printing or 1/180 inch for Letter Quality. If the
distance is negative (Most Significant Bit of m2 equal to 1), the print head will be moved to the
left of the current position by a number of dots equal to the complement on two of n

12

ESC 0

Sets vertical spacing to 1/8 inch.

ASCII Code ESC 0
Hexadecimal Value 1B 30
Decimal Value 27 48

This code causes vertical spacing to be set to 1/8 inch.

ESC 1

Sets vertical spacing to 7/72 inch. (IBM)

ASCII Code ESC 1
Hexadecimal Value 1B 31
Decimal Value 27 49

This command causes vertical spacing to be set to 7/72 inch.

ESC +

Sets n/360-inch line spacing. (IBM)

ASCII Code ESC + n
Hexadecimal Value 1B 2B
Decimal Value 27 43
Range 0 <

n

n

n < 255

This command sets the line spacing to n/360 inch. If the line spacing is changed, it does not
affect previous settings for vertical tabs or pa ge length..

13

ESC 2

Sets the vertical spacing to 1/6 inch. (EPSON)

ASCII Code ESC 2
Hexadecimal Value 1B 32
Decimal Value 27 50

This command causes the vertical spacing to be set to 1/6 inch.

ESC 2

Enables the vertical spacing set by ESC A. (IBM)

ASCII Code ESC 2
Hexadecimal Value 1B 32
Decimal Value 27 50

This command enables the vertical spacing sets by ESC A.

14

ESC 3

Sets vertical spacing to n/180 inch. (IBM XL24 AGM, EPSON)

ASCII Code ESC 3 n

the current setting. The n1 to nx parameters specify the number of columns at which horizontal
tab stops are required and must be entered in the sequence in ascending numerical order. Any
value outside this range will be ignored. In IBM mode, the tab stop position is memorized as
logical position i n the pag e so that i t i s affected by chang ing the horizonta l spa cing. The col umns
are numbered 1 through 136. In EPSON mode , th e tab st op pos ition s et b y ES C D is memoriz ed a s

The skipover perforation is the sum of top and bottom margins values at the selected vertical
spacing. The n parameter must be less than the current form length. The skipover i s memorized
as physical position on the page. It is cancelled by ESC O or changing the form length.

The skipover value, when accepted, will set the top and bottom margins according to the
operator panel setting (see User Manual in this CD-ROM):

If the top margin set via operator panel is greater than the skipover value, then the following
value of the margins will be set:

Top margin = skipover value
Bottom margin = 0
If the top margin set via operator panel is less or equal to the skipover value, then the following

value of the margins will be set:
Top margin = operator panel value
Bottom margin = the difference between skipover value and top margin value
If the sum of the top and bottom margins values set via operator panel is less than the skipover

value, the following values for the margins will be set:
Top margin = operator panel value
Bottom margin = the difference between skipover value and top margin value

Changing the vertical spacing does not affect the skipover distance. This can be changed by a
further ESC N command or can be reset by the ESC O command, which resets the skipover
value to 0. The skipover perforation will be executed when the end of the page is reached with a
LF, VT or FF code and not with the ESC J or ESC C command, the skipover perforation is
cancelled and must therefore be set again.

22

ESC O

Disables the skipover perforation.

ASCII Code ESC 0
Hexadecimal Value 1B 4F
Decimal Value 27 79

This sequence sets the number of lines of the skipover perforation to the value 0 a nd so any ski p

20 cpi 1 < n < 255
24 cpi 1 < n < 255

Any value outside the accepted range is i gnored and the previous setting remains in effect. The
right margin must be greater than the left margin. The physical position set for the right margin
does not change if the horizontal spacing is modified.

right margin value must not exceed the physical right edge of the paper; otherwise the
maximum acceptable value for the right margin will be set.

25

FF

Advances paper to the top of the next page.

ASCII Code FF
Hexadecimal Value 0C
Decimal Value 12

This code is a terminator code, when received, ca uses all data in the print buffer to be printed
out. Then it advances the paper to the first printable line of the next form. The line counter is set
to the first line value and the column counter is set to the left margin value. This code cancels
the double width printing set by SO code.

HT

Moves logically the print carriage to the next horizontal tab stop.

ASCII Code HT
Hexadecimal Value 09
Decimal Value 9

This code moves logically the print carriag e to the next horizontal tab stop as defined by ESC D.
Up to 28 (IBM mode) or 32 (EPSON mode) horizontal tab stops can be set. The HT code is
ignored if no tab stop has been set or if the current print carri age position has moved past the
last tab position or if the tab stop is on or beyond the right margin. At power on, the tab stops
are set every eight columns (default).

In EPSON mode, the default tab stops are memorized as logical position in the page, so that are
affected by changing the horizontal spacing. The tab stop positions set by ESC D are memorized
as physical position in the page and therefore they are not affected by changing the horizontal
spacing. When the double width printing is selected, the tab stop setting must take account that
each character occupies two columns. In IBM mode, the tab stops, both, default and set by ESC,
are memorized as logical position in the page, so that are affected by changing the horizontal
spacing. The horizontal tab stops can be changed by the ESC D command.

26

VT

Advances paper to the next vertical tab stop of the selected VFU channel.

ASCII Code VT
Hexadecimal Value 0B
Decimal Value 11

This code is a terminator code and when receiv ed causes the contents of the print buffer to be
printed before advancing paper to the next vertical tab stop set by the ESC B or the ESC b
commands.

This code will be executed normally, if vertical tab stops follow the current print position. It will
be executed like a FF code (EPSON mode) or like a LF code (IBM mode), if the vertical tab stops
follow the bottom of form position (which corresponds to the form length if the bottom of form
has not been set) or if the current position is beyond the last vertical tab stop. It will be executed
like a LF code if no vertical tab stops have been set by the ESC B or ESC b commands.

In EPSON mode, the vertical tabul ations are referred to the VHF channel selected b y the ESC /
m. If no VFU channels have been selected, the printer assumes as default channel 0.

This command resets the double width printing set b y SO or ESC SO command.

This escape sequence is used to download fonts into the printer. Once fonts have been
downloaded they can be selected by ESC % n.

Parameter n is the character position of the first character and parameter m is the character
position of the last character to be downloaded. F or example, to download character “RST” the
user would specify n=52H and m=54H. Characters must be dowloaded to consecutive positions
after the first character. The parameters a0, a1 and a2 must be sent for each character being
downloaded and are known as the attribute bytes. Parameter a0 specifies the number of dot
columns to be added before the character.

Parameter a1 specifies the width of the character.Parameter a2 specifies the number of dot
columns to add after the character. The parameters d1 …dx represent the dot column data being
downloaded for each character. 2 or 3 data b ytes represent 1 column of dots depending upon the
print mode type as shown below. Draft, Letter Quality and super/subscript fonts can be
downloaded. It is necessary to sel ect the desired print mode prior to sending the downl oad data.
Each dot column has a width of 1/120 ” in Draft and 1/360 in Letter Quality. Following are limits
of parameters a0,a1 and a2 for LQ Draft and Super/Subscript print mode at various character
pitches.

If a data bi t has a value of 1 , then the corresponding wire is fired. If a data bit has a value of 0,
then the wire is not fired. In general the user of this feature must be careful that the number of
bytes of downloaded information is equal to 3 x width of the character being defined (a1) or the
results will be unpredictable. Only one print mode type may be downloade at a time. That is, if
draft characters have been downloaded, then selecting Letter Quality and downloading
characters will cause the draft download characters to be cleared. This applies similarly to script
characters.

This sequence allows you to design and then down-line load special characters not present in the
character set in use. Whenever you would like to start the DLL setting procedure, proceed as
follows:

• Copy the character generator in ROM into RAM

• Select the DLL generator

There are 256 entries of 9 bytes that compose the look up table of a character generator. One
entry describes one character as follows:

Byte 1, 2 The a bsolute address of the character definition.
Byte 3 :

- Bit 7 1: indicates that the character is a graphic character (connects at 6 lpi)

0: indicates that the character is an alphanumerical character

- Bit 6 0: indicates a D LL character

1: indicates a resident character

- Bit 5 to 0 These 6 bits indicate the effective number of dot columns of the character shape
stored in memory.

63

Byte 4:

- Bit 7, 6 Graphic character description:

- 0: shading character

- 1: line drawing character

- 10: underscored character

- 11: not supported
All graphics characters are 30 dot high. An underscored character is defined as a

blank graphic (all zeros) and it is automatically generated by the printer. A
shading character repeats dots 1-6 of each column as dots 25 through 30
respectively. A line drawing character repeats dots 23 and 24 as the pairs 25
and 26, 27 and 28, 29 and 30.

- Bit 5 to 0 The number of dot columns of the character shape minus one. For example: the
character width of Draft generator is 10 dots and bit 5 to 0 must be set to 9.

- Bit 5 to 9 Compression mask description. It is used to optimize the memory occupation
and it is based on the concept that a dot column on its left is not stored. You can
calculate the compression mask of a character only after designing the entire
character. Every bit is associated with a dot column with the bit 7 of byte 5
associated with the leftmost column. The bit is set to {1}, if the column is equal
to the preceding one; otherwise, it is set to {0}. If the character is longer than 39
dot columns the remaining dot columns must be stored without compression.
The bit 40 (bit 0 of byte 9) must be 0. If no compression is present in the
character, byte 5 to 9 is composed by all zeros.

64

If you wish to copy an entry over another entry so that two characters with the same
characteristics and different code are present in the same look up tab le, the DLL sequence ESC
= n m id p t has the following meaning:

n and m: Indicate the byte number of the sequence n is the low part and m is the high

part.

id:

Indicates the printer model. The id related to your printer is 23H.

p and t: Indi cate the memory address of the character that you wish to replace. p is the

low part and t is the high part.

data:

Is the entry 9 bytes of the character that you want to position at address
specified by p and t.

n 10 p EM

CODE-GP bar code allows bar codes to be constructed from the two basic
elements (BAR and SPACE) b y sending 0,1 digits: digit 0 produces a BAR and
digit 1 produces a SPACE.

These two elements may be combined in any sequence, thus giving the
possibility of producing bars and spaces of any width that is a multiple of the
basic element width. Default bar/spaces width is 1/60” (q = 0,1) but these values
may be set by the user according to its specific needs. Data fields do not have a
defined format length and contain 0,1 data only; question marks will be printed
in place of HRC string otherwise, if possible.

No Human Readable Interpretation is possib le, hence is the user task to prov ide
a TEXT STRING below or above the bar/space symbol: f field is meaningless. No
internal check digit algorithm is available: o field is meaningless.
