Chapter 7: Programming Guide 7-49

65,516/256 = 255, remainder of 236

n1 = 236 n2 = 255

To move to the right:

Determine the value of n by multiplying the number of columns to

move right of the current position by 10 (slip or receipt standard pitch)

or 8 (receipt compressed pitch). The example shows how to set the

relative position two columns in standard pitch (10 dots per column) to

the right of the current position.

2 x 10 = 20 dots (two columns to be moved right of the current

position)

20/256 = 0, remainder of 20

n1 = 20 n2 = 0

Related Information:

If the Set Horizontal and Vertical Minimum Motion Units command

(1D 50) is used to change the horizontal and vertical minimum motion

unit, the parameters of this command (Set Relative Print Position) will

be interpreted accordingly. For more information, see the description

of the Set Horizontal and Vertical Minimum Motion Units command

(1D 50) in this document.

Compatibility Information (7158 receipt vs. 7156 receipt)

There is a difference in the normal behavior of this command in A758

Native Mode as compared to the original 7156. The difference exists

when the command is used to move to the left. The 7156 processes the

whole print string prior to putting it in the buffer for the print head.

This method of processing allows the 7156 to backup in the print string

and replace characters and their associated attributes when a “Set

Relative Print Position” command instructs the printer to move the

print position to the left.

In order to improve the speed of printing, the 7158 moves the data into

a buffer for the printhead when it receives it. When the “Set Relative

Print Position” command contains a move to the left, this causes the

new data to overstrike the previous data. This behavior can be used to

an application’s advantage to provide the ability to create compound

characters on the receipt station.
