Cognitive Solutions manual Two-color commands comparison A794 to A799, 1B 59 n1 n2 d1...dn

24	Chapter 3: Programming the Printer		Revision D 12/09
Command		Description	Difference 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 justification	This command does true dot resolution alignment for
			centering versus character-aligned centering.
1D 2A n1 n2 d1...dn]		Define 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.
