Table 4.9

LPD Queue Parameters (3 of 3)

Item

 

Description

 

 

 

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.

 

 

 

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.
