EPSON/IBM Mode

This printer according to the IBM Proprinter XL24E-XL24AGM, IBM 2391 and EPSON LQ 1050-2550 emulations support the following printer commands.

Print and Line Feed Execution

Prints all received da ta and the column counter is set to the left margin. (IBM)

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 le ft 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 received, it causes the current contents of the print buffer to be printed out, be fore reve rsing 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.

A78408098-003

EPSON/IBM Mode

ESC 5

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

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

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 cance ls the automatic line feed.

n Automatic line feed 0 Disabled

1 Enabled

ESC J

Advances paper n/180 inch. (EPSON)

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

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 inch. This command is can celled afte r the line feed has been performed. The printin g will restart af ter a line feed fro m th e co lumn at which the command was sent.

255

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 be fore advancing the pape r by one line at

A78408098-003

EPSON/IBM Mode

the current vertical spacing. If no data precedes the LF code, or if the preceding data consists of spaces , the code ca uses onl y a lin e 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 IB M mode, the column cou nter 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.

Format Control

ESC $

Sets the absolute printing position. (EPSON)

ASCII Code ESC & n1 n Hexadecimal Value 1B 24 n1 n Decimal Value 27 36 n1 n Range 0 < n1 < 255

, n

specified by n

and so on in the 0 VFU ch annel. The tab stops are

memorized as physical positions. In IBM modes, this code sets u p to 64 vertical tab stops at the line

number specified by n

, n2 and so on in the 0 VFU chan nel. The line

at top of form is line 1. The tab stops are memorized as logical positions.

A78408098-003

EPSON/IBM Mode

ESC b

Sets vertical tabs in VFU channels. (EPSON)

ASCII Code ESC b m n1 … n Hexadecimal Value 1B 62 m n1 … n Decimal Value 27 98 m n1 … n Range m = channel

This command sets vertical tabs in one of the 8 VFU channels available. n

… nx 00

1 n2

… nx 0

1 n2

255

This sequence sets up to 28 (IBM mode) or 32 (EPSON mode) horizontal tab stops after canceling the current setting. The n

to n

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 changin g the horizo ntal spacing . The columns are numbered 1 through 136.

In EPSON mode, the tab sto p position se t by ESC D is memor ized 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.

ESC d

Spaces forwards relative dot position. (IBM)

ASCII Code ESC d Hexadecimal Value 1B 64 Decimal Value 27 100 Range 0 <

n1 n

This command moves the print carriage of a (n1 + (n2*256))/120 inch displacement on the right of its current dot position. If the selected position is outside the current right margin, it is forced to the last column.

A78408098-003

EPSON/IBM Mode

ESC e

Spaces backwards relative dot position . (IBM)

ASCII Code ESC e n1 n Hexadecimal Value 1B 65 n Decimal Value 27 101 n1 n Range 0 < n1, n2 < 255

1 n2

This command moves the print carriage of a (n1 + (n2*256))/120 inch displacement on the left of its current dot position.

ESC EM

Loading/ejection of paper. (EPSON)

ASCII Code ESC EM n Hexadecimal Value 1B 19 n Decimal Value 27 25 n

This command controls cut sheet feeding (ASF) according to the parameters below:

n Description 0 Disables

1Bin 1 2Bin 2 3Bin 3 4 Last bin R Ejects cut sheet

ESC l

Sets left margin (10 cpi). (EPSON)

ASCII Code ESC l n Hexadecimal Value 1B 6C n Decimal Value 27 108 n Range 0 < n <

255

This code sets the left margin at the current horizontal spacing. It must be sent at the beginning of the line. The n parameter specifies the number of columns. For each type of horizontal spacing there is a different range of possible va lues, as shown in th e following table.

A78408098-003

EPSON/IBM Mode

Character Width Horizontal Spacing Range of columns Double Width

30 < n

< 67

6 cpi 0 < n < 80

7.5 cpi 0 < n < 100

8.5 cpi 0 < n < 114

12 cpi 0 < n < 160 15 cpi 0 < n < 201 17 cpi 0 < n < 229 20 cpi 0 < n

< 255

Any value outside the accepted range is ignored and the previous setting remains in effect. The left marg in must be smaller than the right margin. The physical position set for the left margin does not change if the horizontal spacing is modified. This command overrides the menu setting.

ESC N

Sets the skipover perforation to n lines. (IBM, EPSON)

ASCII Code ESC N Hexadecimal Value 1B 4E Decimal Value 27 78 Range 1 < n <

127 (EPSON mode)

1 < n < 225 (IBM mode)

The skipover perforation is the sum of top and bottom margins values at the selected vertical sp acing. The n p arameter 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 User Manual):

A78408098-003

EPSON/IBM Mode

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 whe n the end of the page is reache d with a LF, VT or FF code and not with the ESC J or ESC C command, the skipover perforation is cancell ed and must t herefore 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.

A78408098-003

ESC Q

Sets the right margin (10 cpi). (EPSON)

EPSON/IBM Mode

ASCII Code ESC Q Hexadecimal Value 1B 51 Decimal Value 27 81 Range 1 < n <

255

This code sets the line length at the current horizontal spacing. It must be sent at the beginning of the line. The n parameter specifies the number of columns and for each type of horizontal spacing there is a range of values, a s shown in the following table:

Character Width Horizontal Spacing Range of columns Double Width

5 cpi 0 < n < 67 6 cpi 0 < n < 81

7.5 cpi 0 < n < 102

8.5 cpi 0 < n < 116

ESC SP

Sets intercharacter space. (EPSON)

ASCII Code ESC SP n Hexadecimal Value 1B 20 n Decimal Value 27 32 n Range 0 < n <

255

This command sets the intercharacter space to n/120 inch in Draft printing and n/180 inch in Quality printing.

ESC X

Sets left and right margins. (IBM)

ASCII Code ESC X n1 n Hexadecimal Value 1B 58 n1 n Decimal Value 27 88 n1 n Range 0 < n

This command specifies lef t and right margin po sitions. The n

1, n2

< 255

and n

parameters indicate respectively the number of columns for the left and right margins at the current spacing. These margins are memorized in terms of absolute displacement from the physical left edge of the page.

is equal to 0, the current left margin of the page is used. If n2 is equal

If n

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.

EPSON/IBM Mode

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 received, causes all data in the print buffer to be printed ou t. Then it adv ances 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 print ing set by SO code.

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 horizon tal tab stop s can be se t. The HT co de is ignored if no tab stop has been set or if the current print carriage 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 (defau lt). The horizontal tab stops can be changed by the ESC D command.

In EPSON mode, up to 32 horizontal tab stops can be se t. The de fault tab stops are memorized as logical p osition 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. Character scoring (underline, overscore and strikethrough) is not printed between the current print position and the next tab when this command is sent.

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 bef ore adv ancing pap er to the next ve rtical 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 e xecuted like a FF cod e (EPSON mode) or like a L F code (IBM mode), if the vert ic al ta b s t ops fol low t he b ott om of form position (which co rr e spo n ds to th e f o rm le ng th if th e bo ttom o f f o rm has not been set) o r if the c urren t position is be yond the last v ertical 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, th e vertical tabulations are referred to the VHF channel selected by the ESC / m. If no VFU channels have been selected, the printer as sumes a s default channel 0.

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