A776 (B780) Programming Guide 

A776-PG00001 C 12/09

The following table details the list of commands whose behavior differs between the A756 printer and the A758, A760, 
and A776 printers.  This is due to the physical differences of the 6 dots/mm head in the A756 and the 8 dots/mm head 
in the A758, A760 and A776.

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 A756. In text mode, the equivalent character  

 

 

position is calculated.

1B 26 s c1 c2 n1 d1...nn dn 

Define user-defined character set  Since the dots on the A776 printhead are smaller, user  

 

 

defined characters that were used on the A756 printers  

 

 

will appear smaller on the A776 printer.

1B 2A m n1 n2 d1...dn 

Select bit image mode 

In A756 emulation mode, graphics are scaled to best  

 

 

match the size of the graphic in the A756 printer.

1B 33 n 

Set line spacing 

This command uses n in terms of n/360 inches. Since the  

 

 

A756 had a fundamental step of 1/152 inch and the A776  

 

 

has a fundamental step of 1/203 inch, the actual line  

 

 

spacing will not exactly match the requested spacing.

1B 4A n 

Print and feed paper 

This command uses n in terms of n/360 inches. Since the  

 

 

A756 had a fundamental step of 1/152 inch and the A776  

 

 

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 A756 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 A756 emulation mode, this command  

 

 

calculates how many character positions to move  

 

 

based  on the A756 character width in dots (10)  

 

 

versus the A776 (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 A756 emulation mode, this command scales the  

 

 

incoming data to provide a best match to the size of  

 

 

the image as it printed on A756.

1D 2F m 

Print 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 A756.
