User manual EPSON FX-1050

[. . . ] User's Manual EPSON® User's Manual FCC COMPLIANCE STATEMENT FOR AMERICAN USERS This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Subpart J of part 15 of FCC Rules, which are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient the receiving antenna - Relocate the printer with respect to the receiver - Plug the printer into a different outlet so that the printer and receiver are on different branch circuits. [. . . ] And since most characters do not use the bottom two rows, there is a heavy line to indicate the usual lower limit for an FX character. When you place your dots on this grid, remember that dots cannot go on horizontal lines, but they can go on vertical lines. If they overlap other dots, they will not be printed in draft, only in NLQ. As you design your characters, draw the dots as large as the circles you see in the example below. (The printer prints dots, but it is best to use circles when planning your characters. ) Using Software and Graphics 4-21 First definition program The next few sections explain the steps used to create the symbol for Mercury. The figure below shows the grid used to design the character. I Once you have drawn your dots on the grid, type the following BASIC program. 123456789 l!$i3 DIM F(9) 110 FOR I=1 TO 9 120 PRINT "WHICH ROWS HAVE DOTS IN COLUMN";1 130 INPUT R: IF R=@ THEN 150 140 F(I)=F(I)+2"(R-1) 150 IF R=jJ THEN NEXT I ELSE GOT0 130 160 LPRINT CHR$(27) ":"CHR$(0)CHR$(0)CHR$(0); 170 LPRINT CHR$(27)~%nCHR$(1)cH$(0); 180 LPRINT CHR$(27)"&"CHR$(@)CHR$(60)CHR$(60); 190 LPRINT CHR$(128); 200 LPRINT CHR$(27)"x$v'; 210 FOR X=1 TO 9 220 LPRINT CHR$(F(X));:NEXT X 230 LPRINT CHR$(~)CHR$(~); 240 LPRINT "YOUR CHARACTER IN 10 CPI: ( ( (" 250 LPRINT "IN DOUBLE-WIDE EMPHASIZED 10 CPI: '1; 260 LPRINT CHR$(27)"!*( ( (" 270 LPRINT CHR$(27)"!"CHR$(@)"IN NLQ:"; 280 LPRINT CHR$(27)"xl( ( (" 290 LPRINT CHR$(27) "!"CHR$(rjl) "YOUR DATA NUMBERS:" 300 FOR ~=l TO 9: LPRINT F(K);: NEXT K 310 LPRINT: END 4-22 Using Software and Graphics Running the program Now run the program. For each of the nine columns, the program asks for the numbers of the rows in which you want dots to appear. Enter the row numbers one at a time, pressing the Enter key after each one. When you have entered all the numbers for a column or when you want no dots in a column, press Enter without a number. Remember that the vertical lines in the grid are the even-numbered columns. To see the program produce the Mercury symbol, run the program and follow these instructions: 1. When the screen message asks what rows have dots in column 1, press Enter to indicate that no dots go in that column. 2. For column 2 (the vertical line) press 7, Enter, 5, and Enter again to indicate that you want dots in rows 7 and 5. (The rest of the directions assume that you know to press Enter after each number and one extra time to end the entries for each column. ) 4. For column 9 press Enter only. Now wait a moment for your computer to calculate the dot patterns and your printer to print the new character in two different typestyles and Using Software and Graphics 4-23 NLQ. Your printout also gives you nine numbers, which you use in the next program. You should get the printout you see below: When you get to this point with a character of your own, you see how it looks. If you want to make any changes, move the dots as needed and rerun the program. If you want to put dots in the bottom row, change the number in line 190 from 128 to 0. Then the usable rows are those shown in the figure below. 8 7 6 123456789 Second definition program Once the character looks the way you want it to, you can enter, modify, . The program listed here creates the Mercury character, but you can use it for any characters you create if you make one or two changes, as explained after the program listing. 4-24 Using Software and Graphics 90 FOR P=58 TO 63: LPRINT CHR$(P);" "j: NEXT P 95 LPRINT 100 K=l: IF K)3 THEN A=58 ELSE A=60 110 LPRINT CHR$(27~:f'eCHR$(~)CHR$(~)CHR$(~); 120 LPRINT CHR$(27)"%"CHR$(l)CHR$(@); 130 LPRINT CHR$(27)"&"CHR$(~)CHR$(A)CHR$(A-l+K); 140 FOR Z=l TO K 15a LPRINT CHR$(128); 160 FOR X=1 TO 9 170 READ R 180 LPRINT CHR$(R);: NEXT X 190 LPRINT CHR$(@)CHR$(@); 200 NEXT Z 210 DATA 0, 80, 170, 0, 47, 0, 170, 80, 0 290 FOR P=58 TO 63: LPRINT CHR$(P);" "j: NEXT P To use this program for your own character or characters, change the DATA numbers in line 210 by substituting the numbers generated by the first program when you created your own character. If you have created more than one character, put the DATA numbers for each character on a separate line as you see in the example below: 210 DATA 112, 8, ~, 138, 116, 138, 8, 8, 112 220 DATA 56, 68, 146, 40, 13jiY, 40, 130, 68, 56 Check your work by making sure that there are nine numbers in each line and that the numbers are separated by commas. [. . . ] When you print a file from a computer, the contents of the file are transferred quickly from the computer's memory to the printer's memory. The printer then prints information from its own memory at a much slower rate. This way of printing frees the computer to do other work while the printer is still working. The printer memory is sometimes called the buffer. memory micro-adjustment A feature that adjusts the paper loading and tear-off positions. number systems Three number systems are commonly used with printers: decimal is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. (This is the most familiar system. ) hexadecimal (hex) is base 16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. [. . . ]
