/* maximum width, in dots, that we're supporting. The FX80 supported
|
|
* up to 1920 ("quadruple density") -- which I'm not, b/c that's
|
|
* overkill for what I'm doing at the moment. I'm supporting "double density"
|
|
* (960 dots per 8-inch line).
|
|
*
|
|
* My general strategy here is to fill up a line with bits until the
|
|
* printer thinks it needs to move to the next line; and then do
|
|
* something with the bits (send them to a printer, a screen, a file,
|
|
* whatever). This gets both graphics and text modes in one swell foop.
|
|
*
|
|
* There is the troublesome "9-pin graphics mode" where each column of
|
|
* bits is > 1 byte of data; for that, we keep an extra "rowOfPin9"
|
|
* bits, which is just a bit stream across the width. It would be
|
|
* easier to make rowOfBits be uint16_t but it would consume more RAM,
|
|
* and I'm trying to minimize that as I'm down to about 13k of free
|
|
* space in the Teensy!
