This chapter describes the MX-82, MX-82 F/T (hereinafter refered to as MX-82) from the viewpoint of hardware and software. The contents of the chapter are; 1. What is a dot matrix printer? 2. Definitions of some terms often used. 3. Control codes in the text mode 4. Control codes in the bit image mode 5. Print samples in the both modes This printer[...]

The dot matrix printing method allows a printer to easily form any desired character, It has a print head that contains 9 needles vertically and can create distinctive char- acters like with typewriter. In that sense it is one of the key features that the printer has. EPSON’s MX-82 can control each needle programmably, expanding the ability of th[...]

This is called “Dot Matrix Printing”. Dots are printed according to a pre-designed “Matrix” or “Grid” system, where each letter, number and punctuation mark is formed by arrangement of dots. In the above figure, the print head moves from left to right. Since the MX-82 is a bi- directional printing type, the head can also move from right[...]

2. Definitions of Some Terms Often Used Before looking at the printer in detail, some terms should be defined first so that you can understand them more easily and in less time. They are; * ASCII code * Escape codes * “+” symbol * 2, D and H If you are already familiar with the above terms, skip these paragraphs. (1) ASCII code Characters in co[...]

The “ESCAPE” codes used in the MX-82 should not be confused with the es- cape key which some computers have. So be familiar with EPSON’ S control codes. (3) “+” symbol You will see “+” symbol often in the explanation or description of control codes from now on. This symbol is used for legibility only and may not be input in your actua[...]

Back space NU[...]

(3) VT (Vertical Tabulation) When the VT code is input, all data preceding this code is printed and the vertical tabulation is made to a predetermined line position set by “ESC B” (up to 8 posi- tions). If no vertical tab position is set by ESC B, the VT code behaves like the LF code. Therefore, the paper is advanced one line after printing. (4[...]

(4) ESC A + n (for setting amount of line spacing) This code specifies the amount of line spacing in the Line Feed, provided that (n)o must satisfy the condition: 1 s (n)b Z 85 (Decimal). “n” - 1 is equivalent to 1/72 inch paper advancement. Since the distance bet- ween any two dot wires of the print head is 1/72 inch, any line spacing in incre[...]

(5) ESC 0 input of the ESC 0 causes the subsequent line spacing to be set at 1/8 inch. (6) ESC2 Input of the ESC 2 causes the subsequent line spacing to be set at either 1/6 inch or 1/8 inch depending on the initial set condition of the DIP switch pin 1-1. (7) VT (Vertical Tabulation) See paragraph 3.1 (3) above. (8) ESC B + nc + n2 + + nk + NUL (1[...]

(9) FF (Form Feed) See paragraph 3.1 (4) above. (10) ESC C + n (for setting a form length) ESC C + n (n + 0), ESC C + [O]H + m (for setting form length) The “ESC C + n” codes specifies the form length which is determined by the number of lines (n: 1 s (n)n $ 127 where the value of “n” is a positive numb- er and must not exceed 127 lines). I[...]

End of previous page Top of form position Beginning of next page (12) ESC 0 This code cancels the skip-over perforation set by the ESC N + n code. 3.3 Character designation codes (1) SO (Shift Out) (for enlarged characters) [...]

(2) SI (Shift In) (for condensed characters) When the SI code is input, all data that follows it will be printed out in condensed characters. This code is cancelled by the input of “DC 2” code. The SI code can be input at any column position on a line, but all characters/symbols on the line containing SI code are printed out in condensed charac[...]

(7) ESC E (for emphasized characters) The ESC E code causes the Printer to print emphasized characters. Emphasized printing gives the character stronger impression on the paper. This code can be input in any column position on a line, but all characters on the line containing ESC E code are printed out in emphasized characters. The speed of the hea[...]

3.4 Other codes (1) DC 1 (Device Control 1) The DC 1 code places the Printer in the Selected state. It enables the Printer to receive data. W ith the Printer in the Selected state, if the DC 1 code is input during data transfer, all data stored before the DC 1 code is ignored. (2) DC 3 (Device Control 3) The DC 3 code places the Printer in the Dese[...]

(6) BS (Back Space) The BS code cancels the data immediately preceding this code in the Text Mode. In other words, one byte data stored prior to the BS code is cleared from the print buffer, as though that data has not been transferred from the host com- puter. Note that this code is valid only in the Text Mode. (7) NUL (Null) The NUL code is regar[...]

4.1 Normal-density bit image mode setting by ESC K + nl + nz To convert the printer’s operation mode from Text to Normal-density Bit Image, the “ESC K + nl + nz” code must be input. (Here, the sign “+” is inserted for the purpose of legibility only and should not be input in actual operation.) Namely, when ESC (< 1 B> H and K (< [...]

4.2 Dual-density bit imagemode setting by ESC L + nl + nz When the ESC (< 1 B> H ) and L (< 4C > H ) codes followed by data nc and n2 are input, the printer’s operation mode is converted from Text to Dual-density Bit Image. The transfer sequence of bit image data is the same as with the ESC K (normal-den- sity bit image printing), but[...]

4.3 Relationship between data and dot wires Fig. 63 shows the relationship between the Bit Image data and the dot wires in the print head. You can control arbitrary 8 dot wires in the print head. LSB Input data Dot wire l - NOTE: 04 In the Bit Image mode, the 9th dot wire cannot be used. l - 0 .- l - 0 - & Fin. 63 Relationship between Data and [...]

4.4 How to obtain nl and n2 In the MX-82 Printer, you have to send the amount of data by nr + n2 in hexadecimal numbers following the ESC K or ESC L. If the amount of bit image data is 300, then nt and nz may be derived as follows; nl = (Amount of data) MOD 256 = 300 MOD 256 = <44>D = <2c>H n2 = INT (Amount of data/256) = INT (300/256) [...]

4.5 Programming examples (1) Dual-density bit image printing Fig. 65 Example of Graphic Pattern Formation NOTE: The most significant bit (MSB) of the bit image data corresponds to the dot wire at the uppermost position. For example, to print a graphic data as shown in Fig. 65, a program such as shown below must be executed. However, this program ha[...]

With this signal being at “LOW” level, the paper is automatically fed one line after printing. (The sig nal level can[...]

3. All interface conditions are based on TTL level. Both the rise and fall times of each signal must be less than 0.2 p.s. 4. Data transfer must not be carried out by ignoring the ACKNLG or BUSY signal. (Data transfer to this printer can be carried out only after con- firming the ACKNLG signal or when the level of the BUSY signal is “LOW’.) (4)[...]

NOTES: 1. In Table A2-2, it is assumed that as soon as the Printer receives data, it sends back the ACKNLG signal, though this data is not stored in the print buffer. In this status, the Printer is waiting for the DC 1 code for normal entry. 2. In the above table, it is also assumed that no ERROR status exists other than that attributable to the OF[...]
