Comparison Chart
The following table details the list of commands whose behavior differs from the
A756 because of the physical differences of a 6 dots/mm head (A756) versus an 8
dots/mm head (A758).
Command Description Difference between A756 and A758
configured in A756 Emulation Mode.
15
n
Feed
n
Dot Rows This command will move the paper on the receipt
in n/203 inch steps instead of n/152 inch steps.
16
n
Add
n
Extra Dot Rows The dot rows will be measured in n/203 inches
versus n/152 inches.
1B 20
n
Set Right-Side Character
Spacing
This command sets the right side spacing to “n”
horizontal motion units. By default, these units
are in terms of 1/203 inches versus 1/152 inches.
1B 24
n1 n2
Set Absolute Starting
Position
For graphics commands, the position is scaled to
best match the previous product. In text mode, the
equivalent character position is calculated.

] Define User-Defined
Character Set
Since the dots on the new printhead are smaller,
user-defined characters that were used on the
previous printer will appear smaller on the new
printer.

Select Bit Image Mode In A756 Emulation Mode, graphics are scaled to
best match the size of the graphic in the previous
printer.
1B 33
n
Set Line Spacing This command uses
n
in terms of n/360 inches.
Since the previous product had a fundamental
step of 1/180 inch and the new product has a
fundamental step of 1/203 inch, the actual line
spacing will not exactly match the requested
spacing.

Select Double-Density
Graphics
In A756 Emulation Mode, the printer scales the
graphics to provide the best match.

Set Relative Print Position The parameter to this command is in units of dots.
However, the command moves and aligns to
character positions. In A756 Emulation Mode, this
command calculates how many character
positions to move based on the previous product’s
character width in dots (10) versus the current
product (13).
1B 61
n
Select Justification This command does true dot resolution alignment
for centering versus character-aligned centering.

] Define Downloaded Bit
Image
In A756 Emulation Mode, this command scales
the incoming data to provide a best match to the
size of the image as it printed on the previous
product.
