Character Map Load data transfer. Character map definitions, which
follow this sequence, are stored in non-volatile memory. The
character map is selected with the GENICOM Select National
Characters (GENSNC) command using the p2 parameter that is
specified in the load sequence for this command. The load is
terminated by a String Terminator (ST) sequence. The downloaded
character map replaces the USA ISO character set in character map
memory.

A single character map containing 128 substitutions may be
specified. A character map may be designated for either the GL table
(codes 20H-7EH) or the GR table (codes 80H-FFH). Any substitutions
not specified within a character map load will be mapped one-to-one.
For example, code 41H will print the character normally found at
location 41H (upper case A). When a character map designated as a
GR map is selected by the GENSNC command (see Character Set
Selection on page 11), the GL map will automatically be mapped
one-to-one. A standard GL (7-bit) character map, such as French A,
may be specified as the base for a downloaded GR (8-bit) character
map, but an 8-bit GR map, code page 866, for example, may NOT be
used as the base for a GL character map.

p5 Reserved. This parameter is marked by inserting a semi-colon

p6 A literal string indicating the GENSNC select parameter of an

existing character map (such as 437, 850, etc.) to be used as
a base in which substitutions from this command sequence
may be made. This string may be up to 10 characters in
length and must be specified only if the downloaded character
map is to use an existing map as a base. The string is
terminated by a semi-colon (;). The base character map will
always default to Code Page 437 if an ACT character map is
specified and the downloaded character map is a GR table. If
the downloaded map is a GL table, p6 must specify an
existing GL table as the base or a one-to-one default base will
be used.

p7 A literal string which will be used to identify the character

map in the Progam Mode Font – Country menu. This string
may be up to 20 characters in length and is terminated by a
semi-colon (;). Note that only the first 11 characters of this
string will be used for display purposes.

p8-pn A trio of parameters used to specify the actual character map

substitution. A semi-colon must separate each parameter
within the trio, and a semi-colon must terminate each trio.
The semi-colon is not required for the last trio that
immediately precedes the String Terminator (ESC \).

The elements of each trio are defined as follows:

1 A decimal number that identifies the destination

character. This is the character value received from the
host. For example, an upper case "A" has a decimal value
of 65. Values of 32 through 126 and 128 through 255 are
valid for this element.

The first element processed in the first substitution trio
will define whether the map will be for GL (7-bit) or GR
(8-bit) substitution. If the first element is between 32 and
126 (inclusive), the map will be GL, and the first element
of each trio must also be between 32 and 126. Likewise, if
the first element of the first trio is between 128 and 255,
the map is a GR map and all first elements must fall
between 128 and 255. The character substitution map will
be discarded if this rule is violated.

2 A decimal number that identifies the source character.

This is the location value of the desired character pattern
in the printer font set. For example, an upper case "A" has
a decimal value of 65. Values of 0 through the last

GEK-????? 5000 Series Programmer’s Manual

for this element.

3 Reserved. A semi-colon (;) is required to mark this element

position. A zero is permitted.

(column 132 at 10 cpi for the 13.2-inch machines).

A new left margin takes effect following any line terminator that
normally calls for a print position set to the left. A new right margin
takes effect when the print position reaches the new margin.

Margin settings stored as decipoint values are enforced to the nearest
1/120 of an inch. Character printing operates at 1/120 of an inch.

vertical (p1) and horizontal (p2) size of expanded and oversized
characters. When using expanded characters, the currently selected

Parameter values are percentages of the normal sized character, so
values over 100 are needed for expansion. Expansion factors are
obtained by dividing values by 100.

Example: A parameter value of 526 would be divided by 100 to
produce an expansion factor of 5 (5X expansion). Values less than
100 are treated as 1X expansion.

GRAPHICS

Six-Bit Graphics

The ANSI emulation graphics mode provides both horizontal and
vertical dot plotting methods. These methods enable the printing of
ASCII characters in their binary code form. Since each character has
a unique pattern of 1s and 0s (dots and voids) that make up its
binary code, the correct placement of these binary forms enables you
to form larger images on the paper.

For clarity in the text, a binary 1 (a printed dot) will be shown as an X
and a binary 0 (empty dot position) will be shown as a 0.

In the graphics mode, only the low order six bits of a character are
used (bits 1-6). Looking at an ASCII code chart, the question mark

on the paper. An asterisk "*" is represented by 010101 which would
print the following:

Notice that in horizontal graphics that the character is printed on a
single horizontal dot row. In vertical graphics, the character Is
printed six dots high, a character per dot column.

Using the question mark that prints all dots, a series of these
characters in horizontal graphics produces a one-dot-high solid line
across the paper. The same character in vertical graphics produces a
six-dot high band across the paper.

By repeating, omitting and mixing characters across a page, images
such as graphs, charts. and pictures can be produced.

Dot Patterns and Densities

The chart on the next page shows the dot patterns for each of the
ASCII characters. Each character represents six dots or dot positions,
and their spacing is dependent on the density selected. At 60 dpi
density, the dots are spaced 1/60 inch apart. At 120 dpi, each
character represents six dots spaced 1/120 inch apart.

Other Graphics Considerations

In horizontal format, an LF causes the paper to advance one or two
dot rows based on the vertical dot density, regardless of whether 6-bit
or 8-bit graphics has been selected.

In vertical format, the paper is advanced as the dot rows (6 or 8,
depending on graphics mode) are printed.

Graphics Sequences

ESC P DCS (Device Control String):

density and format previously selected by the ESC [p1;p2;p3 q
sequence. Following this sequence, the printer prints discrete dots
and leaves spaces based on the 1s and 0s in the low order six bits of
each byte received. forming graphic dot rows from left to right. To exit
from dot graphics mode, use ESC \.

While in graphics mode (after ESC P and before the ESC \ sequence),
8-bit graphics can be printed instead of 6-bit by using one of the
following sequences:

ESC " 1 n1 <data bytes> 60 dpi horizontal
ESC " 2 n1 <data bytes> 120 dpi horizontal
ESC " 3 n1 <data bytes> Uses current horizontal and vertical

n1 number of data bytes to follow
<data bytes> n1 bytes of graphics data

When the number of bytes of 8-bit data specified by n1 have been
processed, and prior to receiving an ESC \ sequence, the data will
print as 6-bit graphics.

ELECTRONIC VERTICAL FORMAT UNIT - EVFU

Downline vertical tab loading is accomplished through the EVFU. The
EVFU allows loading a form table with a minimum form length of .33
inches (240 decipoints) and a maximum length of 24 inches (17,280
decipoints).

Since the maximum length is 24 inches, the number of lines is
dependent on the lpi setting. 3 lpi = 72 lines. 4 lpi = 96 lines.
6 lpi = 144 lines, and 8 lpi = 192 lines. Exceeding the maximum
causes a fault.

Downloading the EVFU

 The vertical format type must be set to VtType:Emul VFU through

the control panel using the Program Mode.

 No paper instruction lead (PI) is required.
 When the printer has an EVFU table loaded, VFU will be

displayed on the control panel.

ESC ] !

Loading the Table

Starts EVFU table loading sequence. Each line of the form requires
an entry. Dummy values (filler codes - See Table of Channel Codes on
page 5-30) are required in lines with no channel. Two bytes are
required for each line of the form. Loading Is terminated by the ESC \
sequence.

Decimal: 27 93 33
Hex: 1B 5D 21
BASIC: CHR$(27);"]!";

The first table location is normally loaded with the channel 1 code.
This is defined as the top of form (TOF) channel. The table may be left
without channel 1, and a command to skip to channel 1 will cause a
normal form feed as though there was no VFU. Two bytes are loaded
for each line of the form to be controlled. One or more channel
numbers may be indicated in the two-byte code.

The format of two-byte channel control code is:

Bit Number 8 7 6 5 4 3 2 1

BARCODES

Thirteen different styles of barcodes and POSTNET are available.
Each style (except POSTNET) can be rotated 90, 180, or 270 degrees
and printed with or without a human-readable line (HRL). The
barcode symbol size and density are also adjustable.

Control sequences given in the following text show the proper
syntax needed from the host. The second line has examples of
code written in the BASIC program language.

Entering and Exiting Barcodes

Before the printer can print input data as barcode symbols. The
barcode mode must be both selected and activated. There are two
ways for this to be accomplished depending on the setting of printer
option 1 for both 4800 and 4410 ANSI emulation.

Printer option 1 is used to enable the SI (shift in) and SO (shift out)
ASCII codes to activate and deactivate special mode functions. In this
case, the special mode function is barcodes. With option 1 enabled,
code SO will turn on or activate the barcode mode. SI will turn
barcodes off.

NOTE

ANSI 4800/4410 Strap 1 OUT

Enter the barcode mode of printing with the following control
sequence sent by the host. (See Appendix G for strapping options.)

ESC [ 3 t
LPRINT CHR$(27)*."[3t";

Data sent after the above sequence is interpreted and printed as
barcodes.

Exit the barcode mode using:

ESC [ 0 t
LPRINT CHR$(27);"[0t";

ANSI 4800/4410 Strap 1 IN

(See Appendix G for strapping options.)

ESC [ 3 t
LPRINT CHR$(27);"[3t";
Selects the barcode special mode.

SO
LPRINT CHR$(14);
Activates barcodes and prints all received data as barcodes. (Only
after it has been selected by ESC[3t above.)

36

SI
LPRINT CHR$15);
Deactivates barcodes and allows printing of normal text.

ESC[0t
LPRINT CHR$(27);"[0t";
Deselects barcodes.

When an ESC[0t is received before the SI code, barcodes are both
deactivated and deselected.

Setting Barcode Parameters

Select the style, height, spacing, orientation, and print density for the
barcode using the following escape sequence. The second line in the

Barcode Dimensions

NOTE

The following dimensions are for barcodes printed at 0 and 180
degrees rotation. Barcodes printed at 90 or 270 degrees rotation
will be compressed by a 6:5 ratio due to the difference in size of
the horizontal and vertical grids.

0 No rotation - use currently selected font style, cpi, and

lpi. This is the default setting.

1 No rotation - use special HRL font.

2 90-degree rotation use special HRL font

3 180-degree rotation use special FIRL font.

4 270-degree rotation use special HRL font.

p 10 Horizontal print density

0 60 dpi horizontal by 144 dpi vertical print density
1 120 dpi horizontal by 144 dpi vertical print density

Default for barcode styles 5, 6, 13, and 14 is 120 dpi.
Default for all other styles is 60 dpi.

Barcodes printed at 90 or 270 degrees rotation will print at the
same speed (120 x 144) regardless of the selected horizontal
density.

IMPORTANT

If no parameters have previously been entered, then the
factory default values will be used. If previous values have
been sent from the host. these values will prevail until
changed by the host or the printer is reset using the
initialization switch.

A zero parameter value for p2–p8 will cause the default value
to be selected.

Use semicolons as place holders when changing parameters.

LPRINT CHR$(27);"15;;0}" Changes only parameters 1 and 3.
LPRINT CHR$(27);"[16}" Changes only the style of the barcode.

If no changes are made to the parameters of the barcode, the
printer will use the following factory-set values.

Human-Readable Line (HRL)

The human-readable line is printed 0. 10 inch below the bar code
symbol. The height of the HRL and the 0.10 inch space are not
included in the bar code height parameter (p2).

A diamond symbol appearing in the human-readable line indicates
one of the following conditions:

• Margin overrun. The data to be printed exceeds the available space
remaining inside the programmed margins.

• The DEL character has been received while printing in a bar code
style that permits the use of all 128 ASCH characters.

• An invalid character has been received. An example of this would be
a letter "A" sent to the printer while printing a style 5 bar code. Style
5 (EAN-8) only accepts the digits 0-9.

Font Styles and Enhancements

Non-rotated bar codes can be printed with an HRL in any of the fonts
available to the printer.

If enhancements are desired (e.g., bold, underline, or expanded) the
HRL must be printed using the normal text mode. Print the bar code
symbol(s) without the HRL first. Exit the bar code mode and print the
HRL using the normal text mode with enhancements.

Rotated bar codes use a special font for the human-readable line.

Spacing and Bar Code Editing Aids

There is a 0.25-inch space called a quiet zone at the beginning and
end of every bar code. As a result, the minimum distance between
two horizontal bar codes will be 0.50 inch.

Most bar code styles accept commas. spaces, and horizontal tabs as
delimiters to separate bar codes. A comma will add no additional
space between bar codes, so the separation will be the width of the
quiet zone or 0.50 inch. A space character will add 0.10 inch to the
quiet zone for a total of 0.60-inch separation. A horizontal tab will
add the appropriate number of empty spaces to go to the next tab.

Bar Code Readability Statement

The following information is provided to ensure that the best results
are obtained from your printed bar codes.

Use bar code readers designed to operate in the visible light
frequency range. Optional infrared-readable ribbon cartridges are
available.

Use bar code readers designed to read medium- or low-density bar
code symbols. Avoid readers with apertures less than 7 mils (. 007
inch or . 18mm).

Using bar code size parameters smaller than the default settings may
produce unacceptable results.

Bar Code Program Examples

The following program examples are provided to help you become
familiar with the bar code escape sequences. The programs are
written in BASIC and printed using the LUST command. All bar
codes are actual size.

Test Program

This is the minimum code needed to print a bar code. Use it to test
the printer's ability to print bar codes when more complicated
programs are not producing results.

Line 10 turns on the bar code mode. line 20 contains the data to be
printed as a bar code symbol, and line 30 turns off the bar code
mode.

10 LPRINT CHR$(27); "[3t";
20 LPRINT "1234567890";
30 LPRINT CHRS(27); "[0t";

Error Symbol

This example shows the error symbol in the HRL and the error
pattern in the symbol. The error pattern causes the entire symbol to
be rejected by the bar code reader.

The error was caused by the lowercase "a" being inserted into the
data. The default style, Code 3 of 9. accepts only uppercase A-Z, the
numbers 0-9, and the characters

10 LPRINT CHR$(27); "[3t";
20 LPRINT "1a34567890";
30 LPRINT CHR$(27); "[0t"

ANSI Emulation GEK-99???

42

Changing Parameters

This example changes the style p1, height p2, and the HRL font p9 of
the bar code. Notice that semicolons are used as place holders for the
parameters not being changed.

Line 10 - change style to Code 128, change height to 1/4" (3/12").
and use the special HRL font.

10 LPRINT CHR$(27);
20 LPRINT CHR$(27); "[3t";
30 LPRINT "1234567890";
40 LPRINT CHR$(27); "[0t"

Commas and Spaces as Delimiters

When a comma delimiter is used to separate bar codes, no additional
space Is added to the quiet zones. Since the ending .25-inch quiet
zone of one bar code symbol meets the beginning quiet zone of the
next bar code, a total of . 50 inch separates the two. Style 7 (line 5) is
used for these examples since Code 11 uses both spaces and commas
as delimiters.

10 LPRINT CHR$27); "[7}";
20 LPRINT CHR$27); "[3t";
30 LPRINT "1234,56,7890";
40 LPRINT CHR$27); "0t"

When spaces are used as delimiters, an additional 1 inch is added to
the quiet zones. Note that multiple spaces can be used.

Horizontal Spacing

Use horizontal tabs for spacing bar code symbols across the page.
Line 10 sets horizontal tabs at 1440 and 2880 decipoints (2 and 4
inches). The HT codes in lines 40 and 60 cause a jump to the next
tab.

40 LPRINT CHR$(9);
50 LPRINT "5678";
60 LPRINT CHR$(9);
70 LPRINT "9012";
80 LPRINT CHR$27); "[0t"

When no horizontal tabs are set, an HT code acts as a space. adding

0.1 inch to the separation. Total separation is 0.6 inch when the HT
is added to the quiet zones.

Line 10 clears all previously set horizontal tabs for this example.

80 LPRINT CHR$(27); "[0t"

Printer Option Strap 13, Group 2 IN

Printer control strap 13 is used for positioning the paper after
printing a bar code. Strap 13 IN sets the paper to the top of the bar
code after printing; strap 13 OUT leaves the paper position as is after
printing

The state of strap 13 can be checked and changed using the
configuration menu.

In the following examples, lines 10-30 print the bar code symbol and
line 40 adds a line of text to be printed.

Examples 1 and 2 show the effect strap 13 has on the position of the
text.

In example 3, the semicolon at the end of line 30 has been deleted to
show that strap 13 only affects the same horizontal zone that the bar

44

code occupies. The semicolon in BASIC Is used to suppress a LF/CR
after an LPRINT statement.

IMPORTANT

Strap 13 is only effective after exiting the bar code mode. As in
the printout above, printing multiple bar codes without exiting
(line 80 above) causes all the bar codes to be printed in the
same horizontal area of the paper regardless of the condition of
strap 13. Also, some form of printable data must be on the line
before a paper move command (see line 40 in the examples); if
not, the paper will not backup to the top of the bar code.

OVERSIZE CHARACTER FONT

The oversize font is composed of special block-style characters that
can be expanded 156 times the size of standard fonts. This will
produce letters up to 15.25-inches (388mm) high by 13 inches
(330mm) wide. Oversize characters can be rotated 90, 180, or 270
degrees.

Do not confuse oversize characters with expanded characters. The
expanded character feature, (standard in your printer), expands all
existing fonts up to 8 times the normal size. These characters are not
rotatable.

The oversize character feature works with the ANSI protocol.

Entering and Exiting Oversize

The following sequences are used to enter, rotate, and exit oversize
printing:

ESC [ 0 | Exit oversize printing.
ESC [ 1 | Select oversize font with no rotation.
ESC [ 2 | Select oversize font with 90-degree rotation.
ESC [ 3 | Select oversize font with 180-degree rotation.
ESC [ 4 | Select oversize font with 270-degree rotation.

Selecting Size

LPRINT CHR$(27);"[0|
LPRINT CHR$(27);"[0|";CHR$(124);

Once oversize has been turned on, it will remain on until an
ESC [ 0 | sequence is used to turned it off. It does not turn off due to
line terminators (CR and LF).

ESC [p1;p2 B is the sequence used to set the vertical (p1) and
horizontal (p2) size of the oversize characters. A p1 value of 300
would increase the vertical size of the character 300% or 3 times.

The last two digits of each parameter are necessary to comply with
the ANSI standard, but are ignored by the printer. Using the above
example for p1, any three-digit number starting with 3 (300-399) will
be interpreted as 3 times normal size. Likewise, 400-499 equals 4
times, 1200-1299 equals a 12-times increase in size, and so on. The

maximum size is 15600;15600 (156 times) and the minimum or
default is 200;200 (2 times).

Since this same sequence is used to change size in the expanded
mode, the parameters must be cleared to normal size,
ESC [100;100 B, to prevent entering expanded mode when oversize is
turned off.

Decimal: 27 91 p1 59 p2 66
Hex: 1B 5B p1H 3B p2 42
BASIC: CHR$(27);"[";p1;";";p2;"B";

Size Parameters for Rotation

The p1 and p2 size parameters are always relative to a rotation angle
of zero degrees. That is, the characters are expanded first and then
rotated.

Spacing Between Characters

For non-rotated characters and characters rotated 180 degrees, the
horizontal spacing between characters is 1/60-inch times the p2
parameter.

For characters rotated 90 or 270 degrees, the horizontal spacing
between characters is 3/60-inch times the p1 parameter.

Vertical spacing is dependent on vertical paper move commands (LF,
CR, VPR, etc.), the state of menu option GenPrtOpts/Group 2/Strap
13, and the character size and line spacing currently in effect.

Sample Programs

The first example shows the code used to print oversize.

Line 10 sets the size to X3 vertical (V) and X3 horizontal (H). Line 20
enters oversize printing with
printed. Line 40 exits oversize printing. Line 50 returns the size
parameters to X 1 V - X 1 H.

20 LPRINT CHR$(27); "[1|";
30 LPRINT "ABCabc";
40 LPRINT CHR$(27); "[0|";
50 LPRINT CHR$(27); "[100;100B"

no rotation. Line 30 is the data to be

Example 2

The next two examples demonstrate the importance of setting the size
parameters back to X1 V - X1 H after printing oversize. This is the
same program used in Example 1 with an additional line added.

Line 60 prints 1234 in the currently selected font.

10 LPRINT CHR$(27); "[300;300 B";
20 LPRINT CHR$(27); "El:";
30 LPRINT "ABCabc"
40 LPRINT CHR$(27); "CO:";
50 LPRINT CHR$(27); "[100;100 B"
60 LPRINT "1234"

NOTE

In BASIC, LPRINT statements automatically generate an LF/CR
at the end of the line unless suppressed by a semicolon. Since
line 30 does not end with a semicolon, an LF/CR occurred at
the lpi in effect (still in oversize). This accounts for the vertical
distance between the ABCabc line and the 1234 line.

Printer Control Strap GenPrtOpts/Group 2/Strap 13

This printer control strap is used for positioning the paper after
printing oversize characters. When this strap is set to IN, the paper is
positioned at the top of the oversize character after printing; when set
to OUT, the paper position remains as is after printing oversize.

The state of the printer strap can be checked and changed using the
configuration menu.

In the following examples:

 Lines 10-30 print oversize characters at X3.
 Line 50 changes the oversize to X4 V by X6 H.
 Lines 70-80 print oversize and exits.
 Line 90 returns the parameters to X1 to prevent expanded

printing.

 Lines 100-110 print normal text to show the effect that strap 13

has on positioning.

IMPORTANT

Line spacing was set back to normal (6 lpi) when normal text
was selected in line 90. When strap 13 is IN and the paper
position returns to the top of oversize, vertical moves (CR, LF,
VPA, VPR) must be used to move the paper to prevent
overprinting on the oversize characters.
