Star Micronics NX-1000 manual Define NLQ download characters

The most significan bit of the attribute byte is 1 if the character is an ascender (positioned entirely above the baseline) or 0 if it is a descender (descending below the baseline). The attribute byte also indicates the amount of white space to the left of the character (0 to 7 dots, specified by bits 4 to 6), and the width of the character cell, including this space (4 to 15 dots, specified by bits 0 to 3). The left space and cell width at- tributes are used only in proportional spacing.

Each data byte indicates eight vertical dots, with the MSB being the top dot and the LSB the bottom dot. These correspond to pins 1 to 8 or 2 to 9 of the print head, depending on whether the character is an ascender or descender.

For further details, please refer to the Appendix C.

Defines one or more new NLQ characters and stores them in RAM for later use. DIP switch 2-l must be OFF. NLQ mode must be selected before this command is executed. The parameters are the same as for the draft download character command except that the attribute byte specifies right

I .space instead of character width and the dot density is doubled in each direction, so each character consists of 16 dots vertically and 23 dots horizontally and requires 46 data bytes. Dots defined by ml to m23 are printed on the first pass of the head. Dots defined by m24 to m46 are printed on the second pass, the paper being scrolled up half a dot between the two passes.
