AN-14 (Line Printer and Easy Print Modes)
December 28, 2005
AVAILABLE GENERAL QUERIES
The printer can return a lot of information to the host. It can give some statu
configuration. This is all done through a series of query commands that can be issued to the printer. Not all queries are
in all printers, and some queries are available in later versions of printer firmware. All queries are of the same form and
contain 6 bytes (0x1b, “{“ or 0x7b, TWO LETTER QUERY, “?” or 0x3f, and “}” or 0x7d):
ESC {<TWO LETTER QUERY>?}
Legal two letter queries include:

1
Original card reader on non-radio ready printers is approximately 1 inch thick. .BIN files that support this card reader will
have a cr-xyz suffix on the name. The xyz are replaced by “m”, “s”, and “b”, if the Magnetic Card, Smart Card, or Button
features are supported. An “x” occupies that position if the feature is not supported. For example, the 2tcr-msx.bin file is
for the 2t printer with the original thick card reader that supports the Magnetic and Smart cards. Support for this card
reader was last in Version 4.22 firmware.
2
The newer “Slim Card Reader” or SCR was first supported in Version 4.23 firmware and last supported in the 4t in
version 4.33 and the 2t in version 4.34. This card reader is approximately ½ inch thick. The .BIN files that support this
card reader have and scr suffix in the name. For example, 2t-scr.bin is for the 2t printer with the slim card reader. All scr
.bin files support both the magnetic and smart card readers but do not support the button readers.
3
The radio ready printers have supported only the “Slim Card Reader” or SCR, beginning with Version 6.52. The .BIN
files that support the card reader have an “s” in the suffix. For example, 2tr-s.bin is a radio ready 2t printer that supports
the card reader.

Similar to the queries, there are some commands. These have exa
been replaced by “!” (0x21)

ESC{SR:<string>
ESC{SW:<string>
The response to each query is similar. It consists of the comm
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!. T
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 colum
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.
