Compatibility Information (7194 Native Mode and 7197 Series II Native Mode receipt vs.
7193 receipt)
There is a difference in the normal behavior of this command in 7194 Native Mode and
7197 Series II Native Mode as compared to the original 7193. The difference exists when
the command is used to move to the left. The 7193 processes the whole print string prior to
putting it in the buffer for the print head. This method of processing allows the 7193 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 7197 Series II moves the data into a buffer
for the print head 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.
