Epson LQ-2500 User Manual - Page 80

such as emphasized and double-width, one code turns the mode on and another turns it off. For graphics, the commands are more complicated because a code that turns on a graphics mode also specifies how many columns it will use. After the LQ-2500 receives this code, it interprets the next numbers as pin patterns and prints them on the paper. The LQ has one command that allows you to use any of the 11 graphics options. The format of the command is: ESCape =*" m nl n2 data 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 in Table 6-1. Table 61.
