The content of the string. The previous parameter names the string;
this parameter defines its content. When a string name is specified for
a prepend or append string (in the table at the top of the 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
Value
hexadecimal characters. For example, to enter the escape character
(hex 1B), you would type in \1B. If your string includes the backslash
character itself, you can 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.
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 the section on
currently set to be enabled; refer to the

Example:
For example, if you had a network printer controlled by a Windows NT server and
wanted to reset it at the start of each print job, you could set up a user-defined print
queue named "clear_printer" that issues a PCL reset command (<ESC><e>)
at the beginning of each job. You would set this up as follows:
First, set up the print queue:
1. Name a string: Type "reset_string" into the String Name field in row 1.
2. Define the string's value: Type "\1BE" (<ESC><e>) into the Value field in
row 1. (Alternatively, you could type "\1B\45".)
3. Name the queue: Type "clear_printer" into the Queue Name field in
row 5.
4. Set up the prepend string: Type "reset_string" into the Prepend String
field in row 5.
5. Leave the Append String field in row 5 blank.
6. Set the queue type: Using the pull-down menue, set the Queue Type field in
row 5 to "RAW".
Then, set up the printer to use the queue, making sure to specify
LPD Printing for details. LPD printing must be
