The response to each query is similar. It consists of the command repeated, with the “?” replaced by a “!” (0x21). This is
followed by a series of parameter and data pairs. Each parameter and data pair are separated by a semicolon “;” (0x3b).
Each parameter is one or more letters that uniquely identify that parameter for the type of query. This parameter and data
pair is separated by a colon. For example:
Query:
ESC{PH?}
Response: {PH!TD:0384;DD:203;M:M-T102 ;T:24.0C}
This is a response to the printhead query as indicated by the PH!. The first parameter is TD or Total Dots (across
printhead) – this printer is 384 dots wide. The next parameter is DD or Dot Density and is shown as 203 dpi. The M
parameter is the mechanism type and is an M-T102. And finally the temperature of this printhead is 24.0 degrees Celsius.
In the tables below, the VALUES/FORMAT columns will show valid values that will be returned for each parameter, or the
format of the retuned values. The meaning of that value, as indicated by the parenthesis below, is for informational
purposes only and is NOT returned in the query data. An X in the printer type column indicates that parameter or value is
present.
