A799-PG00001D
Command Description Dierence between previous product
and new product emulation mode.
1B 4A n Print and feed paper This command uses n in terms of n/360 inches. Since the
A793 had a fundamental step of 1/152 inch and the A799
has a fundamental step of 1/203 inch, the actual line
spacing will not exactly match the requested spacing.
1B 59 n1 n2 d1...dn Select double-density graphics In A793 emulation mode, the printer scales the graphics to
provide the best match.
1B 5C n1 n2 Set relative print position The parameter to this command is in units of dots.
However, the command moves and aligns to character
positions. In A793 emulation mode, this command
calculates how many character positions to move based on
the A793 character width in dots (10) versus the A799 (13).
1B 61 n Select justication This command does true dot resolution alignment for
centering versus character-aligned centering.
1D 2A n1 n2 d1...dn] Dene downloaded bit image In A793 emulation mode, this command scales the
incoming data to provide a best match to the size of
the image as it printed on A793.
1D 2F m Print downloaded bit image In A793 emulation mode, this command scales the
incoming data to provide a best match to the size of the
image as it printed on A793.
