With such programs you usually create an image on your monitor, then give - Epson LQ-1050X | User Manual - Page 127
graphics you need to know a little about how your printer's print head works. The print head has 24 pins. As the print head moves across the page, electrical impulses cause the pins to fire. Each time a pin fires, it strikes the inked ribbon and presses it against the paper producing a small dot - Epson LQ-1050X | User Manual - Page 128

the format of the graphics command. The Graphics Command The graphics mode command is quite different from the other commands used by the printer. For most of the other printer modes, such as emphasized and double-wide, one ESC code turns the mode on and another turns it off. For graphics, the - Epson LQ-1050X | User Manual - Page 131
The graphics command requires more than one number to specify how many columns to reserve because one line can use thousands of columns, but the printer does not use numbers larger than 255 in decimal. Therefore the graphics mode command uses two numbers, n1 and n2, for reserving columns. To find - Epson LQ-1050X | User Manual - Page 132
be 96 and n2 should be 6 because 1632 = 96 + (6 x 256). The printer interprets the number of bytes specified by n1 and n2 as graphics data, no matter what that you must be sure to supply enough bytes of graphics data or the printer will stop and wait for more data and will seem to be locked.

In fact, planning a user-defined character is like planning a small dot graphics pattern. 4-22 Software and - Epson LQ-1050X | User Manual - Page 139

This manual uses decimal numbers because the program examples are written in BASIC and everyone is familiar with decimals. The data you send to your - Epson LQ-1050X | User Manual - Page 142
you want to print a character in italics, for example, you must have the italic mode turned on when you define the character. The command your printer uses to define characters is one of the most complex in its repertoire. The format of the command is this: ESC & 0 nl n2 d0 dl - Epson LQ-1050X | User Manual - Page 143
actual data that defines the dot patterns for each character. Since it takes three bytes to specify all the dots in one vertical column, your printer expects dl x 3 bytes of data to follow d2. Software and Graphics 4-27 - Epson LQ-1050X | User Manual - Page 144

switch back and forth, at will, between the normal character set and your user-defined character set. It is, however, rather inconvenient. Therefore, your printer has a command that allows you to copy all of the standard characters from ROM to the user-defined character set. The command format is as - Epson LQ-1050X | User Manual - Page 147
Letter Quality Characters If you select Letter Quality printing with the ESC xl command, you can design user-defined characters using up to 29 columns of the Letter Quality/Proportional grid. The dot columns are spaced closer together horizontally than draft dot columns (the horizontal dot spacing - Epson LQ-1050X | User Manual - Page 148
Styles You can use each of the three userdefined character modes (draft, Letter Quality, and proportional) in combination with most of your printer's various print styles. For instance, emphasized mode works with userdefined characters. The characters you design are enhanced to give this printing - Epson LQ-1050X | User Manual - Page 149
