Near-letter-quality characters can also be downloaded. NLQ characters
are printed in two passes of the print head, the paper scrolling half a dot
up between the two passes. The dot matrix therefore has 16 instead of 8
vertical dot positions. The print head travels at half speed, so there are 23
instead of 11 horizontal dot positions.
The dot matrix for an NLQ car symbol is shown in Figure 3-4. The
black dots are printed on the first pass of the print head. The dots printed
on the second pass are shown in white in Figure 3-4, although of course they
too are printed black. In all there are 46 bytes of dot data. As in draft mode,
the printer cannot print adjacent horizontal dots. The procedure for
downloading this character is the same as for downloading a draft character,
except that NLQ mode must be selected by the < 27> < 120> < 49 >
command.
