Enhancing Your Printing You can obtain a wide variety of printing effects with the SQ-850 or SQ-2550, from changing the number of characters printed per inch to using special effects or adding emphasis to selected words and phrases. This section gives you a sampling of the features you may want to select with your software. For software control of [...]

Enhancing Your Printing In 10, 12, and 15 cpi, each character is given the same amount of space. The width of proportional spacing, however, varies from character to character. Therefore, a narrow letter like i receives less space than a wide letter like W. The width of each proportional character is given in the Appendix. The following printout co[...]

Enhancing Your Printing Condensed Both 10 and 12 cpi printing can be reduced to about 60% of their normal width using the condensed mode. This mode is particulary useful for printing wide spreadsheets because condensed 12 cpi allows you to print up to 272 characters on an 13.6-inch line. Condensed can be selected with a software command. Condensed [...]

Enhancing Your Printing Emphasized and double-strike printing Emphasized and double-strike give your printing added emphasis. In emphasized mode, the SQ-850 and SQ-2550 print each character twice as the print head moves across the paper, with the second character offset slightly to the right of the first. This process produces darker, more fully fo[...]

Enhancing Your Printing Overlining, strike-through, and underlining The overline, strike-through, and underline modes are useful for highlighting selected text. This feature can be used to score text, spaces, subscripts, and superscripts without a break. You can choose from a variety of line styles including: single, double, broken, or continuous. [...]

Enhancing Your Printing Selecting typestyles with Master Select Your printer has a special ESCape code called Master Select that allows you to choose many possible combinations of nine different modes: 10 cpi, 12 cpi, proportional, condensed, emphasized, double-strike, double-width, italics, and underline. For more information on sending ESCape cod[...]

Enhancing Your Printing For example, to print a title, you may want to use double-width 12 cpi characters and print them in double-strike mode. You would add three numbers together to calculate the value of n: 12 cpi 1 Double-strike 16 Double-width 32 n = 49 After calculating the value of n, you would use the Master Select command to send the value[...]

Graphics The dot graphics mode allows your printer to produce pictures, graphs, charts, or almost any other graphics you can think of. Because many commercial software programs use graphics, you may be able to print pictures and graphs like the ones on this page and the next by simply giving your software a few instructions. The quickest and easies[...]

Graphics Income Breakdow n The print head To understand dot graphics you need to know a little about how your printer’s print head works. The printer has a 24-element print head. On the SQ, these elements are ink nozzles. Electrical impulses cause the nozzles to transfer ink to the paper to produce a pattern of small dots. As the head moves acros[...]

Graphics Dot patterns Your printer’s print head is able to print graphics as well as text because graphic images are formed on the printer about the same way that pictures in newspapers and magazines are printed. If you look closely at a newspaper photograph, you can see that it is made up of many small dots. Your printer also forms its images wi[...]

Graphics Labeling the nozzles To tell the printer which nozzles to fire in each column, you first divide each of the vertical columns into three sections of eight nozzles each and consider each section separately. Since there are 256 possible combinations of the eight nozzles in each section, you need a numbering system that allows you to use a sin[...]

Graphics With this numbering system, any combination of the eight nozzles adds up to a decimal number between 0 and 255, and no numbers are duplicated. Since there are 24 nozzles in each column, you must make a calculation for each of the three sections in each column. As you can see, this method of planning and printing dot graphics requires consi[...]

Graphics In this command, m selects the graphics option and nl and n2 specify the number of columns to reserve for graphics. The available graphics options are listed below. Option Elements m Horiz.density dots/in. Single-density ! 8 0 60 Double-density 8 1 120 High-speed double-density* 8 2 120 Quadruple-density* 8 3 240 CRT I 8 4 80 -.. . CRT II [...]

Graphics For example, if you wish to send 1632 columns of graphics data, nl should be 96 and n2 should be 6 because 1632 = 96 + 6 x 256. The printer will interpret the number of bytes determined by nl and n2 as graphics data, no matter what codes they are. This means that you must be sure to supply enough bytes of graphics data or the printer will [...]

Graphics Using hand-calculated data to print graphics With what you know now, you can use the simplest application of graphics - using hand-calculated data to print graphic images. While this method is the most tedious, it helps you understand dot graphics. Also, it is useful for small graphic elements that are used many times. The illustration bel[...]

Graphics Write the assigned values of the nozzles next to your design and then total the values for each column of dots. These totals are the values that will be sent to the printer as graphics data to print the design. Below is shown the same grid divided into three sections to make the data calculation easier. At the bottom of each section of eac[...]

Graphics Here is the BASIC program that prints the design shown on the previous pages. Notice that the data numbers in lines 80-140 are the same numbers that you see in the last illustration. Also note that the WIDTH statement in line 10 is for IBM PC BASIC; the format may be different for your system. 10 WIDTH "LPT1:",255 20 LPRINT CHR$([...]

Graphics Adding the following lines to the preceding program will cause the pattern to print 10 times in a row as shown below. 15 FOR C=l TO 10: RESTORE 65 NEXT C Individual graphics option commands As previously mentioned, your printer responds to commands that are used by EPSON FX, RX, LX, and EX series printers. There are four individual graphic[...]

Graphics The reassigning command The SQ has a command that allows you to change the graphics option assigned to any of the four individual graphics options commands. The command looks like this: ESC ? s m The letter s represents the command that you wish to change the assignment for (K, L, Y, or Z) and m is the number of the graphics option that yo[...]

User-defined Characters With this printer, it is possible to define and print characters of your own design. You can design an entirely new alphabet or typeface, create characters for special applications such as mathematical or scientific symbols, or create graphic patterns with user-defined characters to serve as building blocks for larger design[...]

User-defined Characters Design grids To design a character you use a grid that is 24 dots high - one dot for each nozzle on your printer’s print head. The width of the character matrix is dependent upon the character set in use. For draft characters, the grid is nine dots wide. For Letter Quality it is 29 dots wide, and for proportional character[...]

User-defined Characters There is one restriction in designing characters. Dots in the same row may not print in adjacent columns. That is, there must be an empty dot position to the left and to the right of each dot that prints. This is true in draft, Letter Quality, and proportional. Defining your characters The first step in defining characters i[...]

User-defined Characters Data numbers The bits within each byte have values of 1, 2, 4, 8, 16, 32, 64, and 128. In the vertical column of dots, the bits are arranged so that the most significant bit (which has a value of 128) is at the top and the least significant bit (which has a value of 1) is at the bottom. The next illustration shows how to use[...]

User-defined Characters Now you have seen how to design a character by placing dots on a grid and translating the dots to decimal equivalents. The last step in defining a character is to send this information to the printer. Sending information to your printer The printer loads characters in the print style (Letter Quality, draft, or proportional) [...]

User-defined Characters An example will show how to specify nl and n2. If, for instance, you wanted to redefine the characters A through Z, nl would be A (or ASCII code 65) and n2 would be Z (or ASCII code 90). So the command ESC & 0 AZ (followed by the appropriate data) would replace the entire alphabet of capital letters. Following the specif[...]

User-defined Characters 60 READ A: LPRINT CHR$(A); 70 NEXT I 80 LPRINT "@@@@@" 90 LPRINT CHR$(27)"%"CHR$(l); 100 LPRINT "@@@@@" 110 LPRINT CHR$(27)"%"CHR$(~); 120 LPRINT "@@@@@" 130 END 140 DATA 1,0,0,2,0,0,4,0,0 150 DATA 8,0,0,23,255,240,8,0,0 160 DATA 4,0,0,2,0,0,~0,0 In line 10, the ESC x0 comman[...]

User-defined Characters Run the program to see the printout below: As you can see, both sets of characters (the original ROM characters that the printer normally uses and the user-defined character set) remain in the printer available for your use. The command to switch between the two sets is used in line 90 and 110. It is: ESC % n If n is equal t[...]

User-defined Characters Therefore, your printer has a command which allows you to copy all of the standard characters from ROM to the user-defined character set. The command format is as follows, where the value of n represents the font family: ESC: 0 n 0 Note: This command will cancel any user-defined characters you have created. You must send thi[...]

User-defined Characters Remember that in Letter Quality and proportional modes, as in draft, you cannot place dots in adjacent columns. There must be an empty dot position to the left and right of each dot that prints. Superscripts and subscripts You can also create superscript and subscript user-defined characters. Just as Letter Quality character[...]

User-defined Characters Since super/subscript characters are smaller, they do not require as much information when you define them. When you define super/subscript characters, you need only two bytes of data for each vertical row of dots. Design grids for these characters are shown in the figure below. Software and Graphics 4-31[...]

User-defined Characters Mixing print styles Each of the three user-defined character modes (draft, Letter Quality, and proportional) can be used in combination with most of your printer’s various print styles. For instance, emphasized works with user-defined characters. The characters you design are enhanced to give this printing effect. Mixing t[...]

Glossary bit A binary digit (0 or l), which is the smallest unit of information used by a printer or computer. See also number systems. buffer See memory. byte A unit of information consisting of eight bits. carriage return The control code that returns the print position to the left margin. In bidirectional printing, the print head may not actuall[...]

Glossary control code Besides the codes for printable characters, the ASCII standard also includes 33 other codes which are called control codes. These control codes perform such functions as sounding the beeper and performing a carriage return or line feed. cut sheet feeder An optional, detachable device that automatically feeds single sheets of p[...]

Glossary double-strike printing A way of producing bolder characters. Each character is printed twice in a single pass of the print head: the second time, the dots are printed slightly below the original dots. Can only be used in draft mode. draft One of two print qualities available on your printer. Draft uses a minimum number of dots per characte[...]

Glossary form feed A control code and a panel button that advances the paper to the top of the next page. hexadecimal (hex) See number systems. initialize To establish the initial default status of the printer by turning the printer on or sending an INIT signal. interface The connection between the computer and the printer. A parallel interface tra[...]

Glossary memory The printer, like a computer, has a memory. 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 [...]

paper-out sensor A small switch behind the platen that sends a signal when it is not in contact with paper, causing the PAPER OUT light to go on. parallel interface See interface. parity Parity is a method for a computer and printer to check the reliability of data transmission. pitch Indicates the number of characters per inch (cpi). The standard [...]

Glossary push tractor A built-in device that moves continuous paper through the printer. RAM Random Access Memory. The portion of the printer’s memory used as a buffer and for storing user-defined characters. All data stored in RAM is lost when the printer is turned off. reset To return a printer to its defaults, by either a command, an INIT sign[...]

Glossary unidirectional printing Printing in one direction only. Allows more precise vertical alignment than bidirectional printing. Often used for printing graphics. user-defined characters Characters that are defined and stored in the printer by the user. Also known as download characters. Glossary GL-9[...]
