This printer according to the IBM Proprinter XL24E, IBM 2391 and EPSON ESC/P2
emulations supports the following printer commands.
PPrriinntt aanndd LLiinnee FFeeeedd EExxeeccuuttiioonn
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 da ta 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.
9
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 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)
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
This is a terminator code; it therefore causes the current contents of the print buffer to
be printed out before advancing the paper b y one line at the current vertical spacing.
If no data precedes the LF code, or if the preceding data consi sts of spaces, the code
causes only a line feed.
10
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.

This sequence sets up to 28 (IBM mode) or 32 (EPSON mode) horizontal tab stops
after canceling 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 in the page so that
it is affected by changing the horizontal spacing. The columns are numbered 1 through
93.
In EPSON mode, the tab stop position set by ESC D is memorized as physical position
in the page and therefore it is not affected by changing the horizontal spacing. The
physical position of the tab stop depends on the horizontal spacing in operation when
ESC D is used. The ESC D 0 cancels all active tab stops.

The skipover perforation is the sum of top and bottom marg ins values at the selected
vertical spacing. The n parameter must be less than the current form length. The
skipover is 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 the User Manual):
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
30
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 comma nd, 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 cancel led and must therefore be set again.
ESC O
Disables the skipover perforation. (IBM, EPSON)
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 and
so any skip perforation set by ESC N is cancelled.
ESC Q

ASCII Code ESC Q n
Hexadecimal Value 1B 51 n
Decimal Value 27 81 n
Range 1 <
This code sets the line length at the current horizontal spacing. It must be sent at the

If n1 is equal to 0, the current left margin of the page is used. If n2 is equal to 0, the
current right margin of the page is used. The left margin value must be less than the
right margin value. The 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.
33
FF
Advances paper to the top of the next page. (IBM, EPSON)
ASCII Code FF
Hexadecimal Value 0C
Decimal Value 12
This code is a terminator code, when receiv ed, causes 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
Horizontal Tab. (IBM, EPSON)
ASCII Code HT
Hexadecimal Value 09
Decimal Value 9
This code moves logically the print carriage to the next horizontal tab stop as defined
by ESC D.
In IBM mode, up to 28 horizontal tab stops can be set. The HT code is ignored if no tab
stop has been set or if the current print carriage positi on 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). The horizontal tab stops can be changed by the
ESC D command.
In EPSON mode, up to 32 horizontal tab stops can be set. 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
34
spacing. When the double width printing is selected, the tab stop setting must take
account that each character occupies two columns. Character scoring (underline,
overscore and strikethrough) is not printed between the current print position and the
next tab when this command is sent.
VT
Vertical Tab. (IBM, EPSON)
ASCII Code VT
Hexadecimal Value 0B
Decimal Value 11
This code is a terminator code and when received causes the contents of the print
buffer to be printed before advancing paper to the next vertical tab stop set by the
ESC B command.
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 fol low 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 an LF code if no vertical tab
stops have been set by the ESC B command. In EPSON mode, the vertical tabulations
are referred to the VHF channel selected by 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 sequence allows you to design and then down-line load special characters not

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:
70
Byte 1, 2 The absolute address of the character definition.
Byte 3 :
- Bit 7
- Bit 6
1
: indicates that the character is a graphic character (connects at 6 lpi)
0
: indicates that the character is an alphanumerical character
0
: indicates a DLL 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.
Byte 4:
- Bit 7, 6 Graphic character des cription:
-
-
-
-
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.
71
- 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 compress ion
is present in the character, byte 5 to 9 is composed by all zeros.
