Characters to be printed according to the parity error indication code (40)H will differ depending on the setting of the printer character set. Refer to the printer User’s Guide.

Ready/Busy protocol

Block format Free Error indication The parity error indication is printed as character

40(H).

Busy state indication The busy signal turns on (becomes Busy) when the

space in the interface buffer has become less than 256 bytes. The busy signal turns off (becomes Ready) after 200 ms or 1 second has passed if 256 bytes have recovered within 200 ms or 1 second. If the recovery time exceeds 200 ms or 1 second, the busy signal turns off (becomes Ready) immediately after the recovery has occurred.

Timing chart

Technical Reference Guide – Interface specifications > 31

X-ON/X-OFF protocol

Block format Free Error indication The parity error indication character is converted

into code 40(H).

Busy state indication The DC3 will be sent to the transmission side

immediately after the space in the interface buffer has become less than 256 bytes to indicate that receiving is impossible. The transmission of the DC3 stops when data receiving has stopped. If the recovery time for 256 bytes is within 200 ms or 1 second after the DC3 is sent, DC1 will be sent 200 ms or 1 second after the recovery to indicate that receiving is possible. If the recovery time exceeds 200 ms or 1 second, the DC1 is sent immediately after the recovery has occurred.

After the settings outlined in Circuit Test mode setting are completed and power is turned on, the serial interface checks the message buffer memory and interface driver and receiver circuits, then prints all characters. To start and stop this test, press the SEL switch on the front of the printer. Details of this test are explained below.

1. Print the program revision with two numerical characters.

2. Print “LOOP TEST. ”

3. Check memory for message buffer.

Print “GOOD” if memory check is OK, and print “BAD” if memory check fails.

4. Transmit characters from code 20H to 7FH by TD signals. At the same time, characters are received from the RD signal and stored in the message buffer.

5. Print the characters that were stored in the message buffer as indicated in Step 4.

6. Repeat from Step 1.

EXADECIMAL DUMP MODE

VERVIEW

Normally a printer prints character patterns that correspond with the input character code. The printer does not print function codes or invalid codes. If the printer does not operate normally, the data sent from the host computer must be checked to determine if the commands are correct.

In this mode the printer converts input data into hexadecimal data and prints all the input data, making it is easy to check all the codes sent from the host computer to the printer.

PERATION

1. Entering Hexadecimal Dump mode:

While pressing the SEL+LOAD/EJECT switches, turn on the power.

2. Exiting Hexadecimal Dump mode: Turn the power OFF

3. Print pattern: Hex Dump Mode

> Prints in 10 CPI Utility mode. > Both parallel and USB interfaces are available. > Paper auto Skip Over Perforation (SOP) by menu default

value continuous for both. If SOP is enabled, one inch from the bottom of the paper will not be printed.

> Printing starts when more than 16 bytes of data are

received (line full).

ONTINUOUS PAPER AUTO-LOADING

Load continuous paper on the tractor (at a position such that the paper does not cross the paper-end sensor).

In this situation, pressing the LOAD/EJECT switch starts autoloading.

When the paper does not cross the paper-end sensor within an 8-in feed of the paper, a paper-end state occurs.

The print position of the first data line can be set by menu function or in first character setting mode.

NOTE

TOF is the position that is set when the operation was completed properly.

ONTINUOUS PAPER AUTO-PARKING

With continuous paper loaded in continuous paper mode, pressing the PARK switch starts auto-parking.

When the end of continuous paper is detected by the time the paper is fed 22 in reverse, auto-parking finishes and a paper-end state is established.

If the end of continuous paper is not detected after a 22-in reverse feed, auto-parking terminates. The position that is set when the auto-parking terminated becomes TOF.

Pressing the PARK switch again repeats the auto-parking operation.

Technical Reference Guide – Operator interface > 81

The number of reverse movements using the switch is limited to one.

Do not perform reverse feed if the last sheet of continuous paper will come off the tractor.

CUT-

SHEET PAPER SEMI-AUTO-LOADING

By loading paper on the input tray in cut-sheet mode or while waiting for cut-sheet feed, semi-auto-loading starts after the menu-set paper feed wait time (0.5 sec/1.0 sec/2.0 sec) has elapsed.

Once started, cut-sheet paper is fed until the print position of the first data line is reached, the printer is placed in the SELECT state and the operation finishes.

The TOF set at that time is the printing start position of the first data line.

ORM TEAR-OFF

UNCTION

Form tear-off allows the user to tear the continuous forms paper at a desired cut position by advancing the paper to the cutting edge of the front upper cover.

SET-

1. Conditions:

(a) Continuous forms paper is loaded into the tractor

feed.

2. Tear Position: (a) Load continuous forms paper.

Press the TEAR switch while On line to move the paper up to tear position.

(b) Adjust to the desired tear position using fine LFs.

Technical Reference Guide – Operator interface > 82

CTION

(a) The paper will advance to the tear-off position

approximately 500ms/1sec/2sec after printing.

(b) When data is received by the printer or the SEL

switch is pressed to select the printer, the paper will retract to the user-defined printing position.

> Out of range:

The number “n” must be within the ranges given above, otherwise it will be ignored.

If n = 0, or is less than or equal to the left margin, this command is ignored.

> Additional details:

The right margin is set as an absolute position, according to the current character pitch. Changes in character pitch do not change the margin setting.

While in proportional mode the character pitch width will be set in pica character size. (ML1190 eco : 10 CPI = 36 dots, ML1120 eco : 10CPI = 12 dots)

Any graphics after the right margin are lost. Setting the right margin clears the print buffer. Minimum difference between left margin and right margin

values is 5 characters for 5 CPI. Attempting to print a character beyond the right margin

will print the character on the next line after a line feed and carriage return are executed.

SET

LEFT/RIGHT MARGIN

> Code: ESC X n1 n2 > Compatibility:

ML1190 eco: IBM ML1120 eco: IBM III

> Function:

Sets the left and right margins in character positions from the home position by the current character pitch.

> Range:

The ranges for n1 and n2 are: 0 <= n1 <= 255 Left margin 0 <= n2 <= 255 Right margin n1 < n2

> Out of range:

If n1 or n2 = 0 then the current margin setting is used. If n2 exceeds the default range n2 will be converted to the

default value.

10 CPI 12 CPI 15 CPI 17.1 CPI 20 CPI

Value 80 96 120 138 160

> Additional details:

The default value of the left margin is the first character. The margin settings are absolute. Changes in character

pitch do not affect the margin position. n1, n2 indicate the left and right edges of printable area.

For example, if n1 = 10, n2 = 100, the printable area is from the 10th column to the 100th column: 91 characters are printable.

UTO JUSTIFICATION

> Code: ESC a n > Compatibility:

Technical Reference Guide – Command descriptions > 94

ML1190 eco: EPSON LQ ML1120 eco: EPS FX

> Function:

The text position/alignment will be set according to one of the four given modes assigned by n. (n is a Binary value.)

> Range:

N JUSTIFICATION

00H Left 01H Centre 02H Right 03H Full

> Additional details:

n = 0: Left justification is the default or standard format, in which the left margin is justified and the right margin is not.

n = 1: The centring command centres a line of text between the margins. This command is used for headings, titles and captions.

n = 2: Right justification is the opposite of left justification. The right margin is justified and the left is not.

n =3: Full justification puts extra spaces where necessary so that both the left and right margins are justified.

Full justification (n = 3) is performed when data exceeding 75% of printable characters in a line is received at the time of print start.

BS, DEL, HT are invalid when auto justification is used except when n = 0.

Technical Reference Guide – Command descriptions > 95

Print position will be affected by the commands which set the left/right margin.

NOTE When using full auto justification, use carriage return at the end of paragraphs only, not at the end of each line of text.

SET/

RESET UNIDIRECTION PRINTING

> Code: ESC U n > Compatibility:

ML1190 eco: EPSON LQ/IBM ML1120 eco: EPS FX/IBM III

> Function:

Unidirectional printing, from left to right, or bidirectional printing will be performed based on the value of n.

> Range:

Range n:

EPSON IBM ACTION

01H, 31H, 81H, B1H ODD SET Unidirectional 00H, 30H, 80H, B0H EVEN RESET (Bidirectional)

> Out of range:

This command will be ignored if n equals a value other than the values mentioned above.

> Additional details:

Short line seeking is performed in both unidirectional and bidirectional print modes.

ONE

LINE UNIDIRECTIONAL PRINTING

> Code: ESC < > Compatibility:

ML1190 eco: EPSON LQ

Technical Reference Guide – Command descriptions > 96

ML1120 eco: EPS FX Function: Unidirectional printing for one line only will be performed.

> Additional details:

The line is printed from left to right. Subsequent lines will be printed, bidirectionally, according

to short line seeking priorities logic. This command returns the printhead to the start of the

print line before printing begins.

SET/

RESET HALF SPEED PRINTING

> Code: ESC s n > Compatibility:

ML1190 eco: EPSON LQ/IBM ML1120 eco: EPS FX/IBM III

> Function:

The printer starts/stops printing at 50% of normal speed upon receipt of this command depending on the value of n.

> Range:

n = 01H, 31H, 81H, or B1H SET half-speed printing. n = 00H, 30H, 80H, or B0H SET full speed printing.

> Out of range

This command will be ignored if n equals a value other than the values mentioned above.

> Additional details:

Half Speed mode can be used to reduce printer noise. If the print speed is slower than the printer’s physical

lowest speed, the half speed command is ignored and data is printed at that lowest speed.

Technical Reference Guide – Command descriptions > 97

ACKSPACE

> Code: BS > Compatibility:

ML1190 eco: EPSON LQ/IBM ML1120 eco: EPS FX/IBM III

> Function:

Prints the data in the print buffer and moves the printhead one character to the left according to the character pitch set.

> Additional details:

If a Multipass character (e.g. double height character) needs to be printed, after the BS the printer performs a back space and a LF to the printing position and prints the character. (Precise printing position is not guaranteed.)

A backspace code given when the printhead is at the left margin is ignored.

Moves back two character spaces if the printer is in double width mode.

If clearance between characters is set, BS value will be character width and clearance.

In proportional mode: EPSON LQ – The first character is back spaced by the width

of the proportional character and subsequently by 10 CPI character width (or reduced 12 CPI character width in Reduce mode). IBM – Back space by 12 CPI character width.

ONE

CHARACTER DATA DELETE

> Code: DEL > Compatibility:

ML1190 eco: EPSON LQ/IBM ML1120 eco: EPS FX/IBM III

> Function:

Technical Reference Guide – Command descriptions > 98

Deletes the last character data input into the print buffer.

> Additional details:

If the data which is to be deleted is a SP code, (20)H or (32)D, one SP code is deleted by this command.

If the data which is to be deleted is in Bit Image Graphics, this command is ignored.

Horizontal tab or skip is not deleted. Control codes are not affected. This command is ignored if auto-justification is set, except

when n = 0.
