2-50 PCL Table 2-14: Description of Command Structure (Continued) Element a # C Description Group character from ASCII table (ranging from 96 to 126 decimal) that specifies a group type of control Decimal character string value within specified numeric ranges; may be preceded by a + or - sign and contain a decimal point Termination character from ASCII table (ranging from 64 to 94 decimal) Command Parameters A command parameter sets the value for a command. This value stays constant until either a different value resets the command or a command resets the printer to the default values. For example, after the printer receives a command that selects a right margin beginning at column 63, the right margin of each printed page begins at column 63. That margin stays constant until a right margin command with a different value resets it or until the printer is reset. Parameters for each command are listed in the command tables beginning on page 2-52. Use the Symbol Set Tables to determine the decimal or hexadecimal value for each parameter. To determine a decimal or hex value, first locate the value of the parameter you require in the Symbol Set Table. The decimal value is the value shown in the bottom of the cell or box with that parameter. To find a hex value, go straight up the grid from the desired parameter and read the value in the top heading. This is the first character of the hex value. Next, go straight across the grid to the left of the parameter and read the value in the left column heading. This is the second character of the hex value. For example, ESC (←) is coded 1B in Hex and 27 in decimal. (Any one of the three values ←, 1B, or 27 might be used in your application. Read your documentation to determine which to use.) The example on the following page sets the pitch of the primary font to 16.66 characters per inch. Example: ESC(s16.66H • Decimal: 27 40 115 49 54 46 54 54 72 • Hex: 1B 28 73 31 36 2E 36 36 48 Use the plus symbol (+) or the minus symbol (-) to select a position relative to the current cursor position. For example: ESC&a6C ESC&a+6C ESC&a-6C Move to horizontal cursor position, column six Move six columns to the right of the current position Move six columns to the left of the current position
