The format of the attribute byte "a" is different for draft and NLQ characters. Draft You can define characters 11-dots wide by 8-dots high. You must specify whether to define the upper or lower 8 dots of the 9 dots available. You can also specify the columns not printed on the left and right of the characters during proportional spacing. Set both these parameters with the a parameter, as described below: Attribute byte table Beginning Column Column Value number 0 0 1 16 2 32 3 48 4 64 5 80 6 96 7 112 Ending Column Column Value number 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11 11 Upper/Lower 8 pins Pin group Value Upper 8 pins Lower 8 pins 128 0 Add up the values for all three settings; the value for a is this total. NLQ The attribute byte a equals the width of the character, between 1 and 12 dot columns. · · · Only NLQ characters can be defined on LX printers, ActionPrinter Apex 80, ActionPrinter 2000, ActionPrinter 2250, and ActionPrinter T-1000. When you switch to NLQ printing on FX printers, the printer enhances user-defined characters to appear as NLQ-mode characters. Defining characters during draft or NLQ mode results in the user-defined characters having the draft or NLQ attribute. You cannot define characters of different attributes at the same time; previously defined characters will be deleted. Always cancel italic characters with the ESC 5 command before defining characters. After defining user-defined characters, you can italicize them by sending the ESC 4 command. Do not define continuous dots on the same row during draft mode; the printer ignores the second of two continuous dots. Send the ESC I 1 command to allow you to print the characters between 128 and 159 and the non-control code characters between 0 and 31. · · · · Individual Command Explanations C-87 Printers not featuring this command None Model-dependent variations All LX-series printers, ActionPrinter Apex 80, ActionPrinter T-1000, ActionPrinter 2250 and ActionPrinter 2000 Only the 6 characters between 58 and 63 can be defined.

Do not change any attributes before modifying characters in the copied font. Always cancel italics with the ESC 5 command before copying ROM characters to RAM. You can italicize characters after copying by sending the ESC 4 command. [. . . ] <MOVX> unit is set by the <MOVXDOT> or <MOVXBYTE> command. If #BC has a negative value, it is described with two's complement. Notes · · · The unit for this command is determined by the ESC ( U set unit command. The parameter of the new horizontal position should be a multiple of eight when the dot unit horizontal move is used. Settings that exceed the right or left margin will be ignored.
