ENWW Using the Embedded Web Server 136
To set up a user-defined print queue, you first define the strings,
assign them as prepend or append strings, and define the queue
type. Once you have defined an LPD queue, you specify its use by
setting up an LPD printer that uses that queue. For instance, if you
set up string “a” with a value of “abc” and string “z” with a value of
“xyz”, you can define print queue “az_queue” with a prepend string
of “a”, an append string of “z”, and a queue type of “raw”. Then, when
you send a print job consisting of <formatted_text> through queue
az_queue, the job sent to the printer is “abc<formatted_text>xyz”.
Instructions for setting up an LPD printer are different for different
operating systems; refer to Chapter 5,
“Configuring for LPD
Printing” for details.
Value The content of the string. The
String Name
parameter names the
string; the
Value
parameter defines its content. When a string
name is specified for a prepend or append string (in the table at
the top of the browser window), the line printer daemon sends
the value of that string to the printer before or after the print data
(as appropriate).
Character values can be anywhere in the extended ASCII range
of 0 to 255 (hex 00 to FF). You can specify a non-printing
character using its hexadecimal value, by entering a backslash
followed by two hexadecimal characters. For example, to enter
the escape character (hex 1B), type in \1B. If your string includes
the backslash character itself, specify it as \5C. The maximum
number of characters you can type into this field is 240. The
characters in the field are checked for hexadecimal values,
converted if necessary, and stored internally. The maximum
number of characters stored internally in the string is 80; any
characters that exceed this are discarded.
