Response

[SOH] <n>…

Description

This command can be placed in the print data and, when processed by the

 

printer, will return a progress status marker. The value of <n> can be any

 

8-bit value. It is returned to the host unaltered. The intent is for it to be a

 

sequence number. This command can be used to track the print progress of

 

the printer or verify that the data has been printed.

Note: This command is a line terminator that causes the printer to print all previous data. If a normal line terminator (like a [CR]) is not supplied, right justify and autocenter will not function correctly. All data will be left justified. [ESC] q does not perform a [CR] or [LF] function.
