Table 4-13 LPD Queue Parameters (continued) Item Description Queue Type Processing instruction for the queue. Choose from these four queue types: ■ RAW-No processing. The line printer daemon treats the data in a raw queue as a print job that has already been formatted in PCL, PostScript, or HP-GL/2, and sends it to the printer without modification. (Note that any user-defined prepend or append string will be added to the job in the appropriate position.) ■ TEXT-Carriage return added. The line printer daemon treats data in text queues as unformatted or ASCII text, and adds a carriage return to each line before sending it to the printer. ■ AUTO-Automatic. The line printer daemon uses autosensing to determine whether the print data should be sent as raw or text. ■ BINPS-Binary PostScript. This instructs the PostScript interpreter that the printjob is to be interpreted as Binary PostScript data. Default Queue Name String Name Value Name of the queue to be used if the queue specified for a print job is unknown. By default, the Default Queue Name is AUTO. Name of a character string. You may define up to eight character strings for use in LPD queues; this parameter names the string, and the Value parameter defines the content of the string. Prepend and Append string names (specified in the table at the top of the browser window) must be chosen from the names specified here. The string name can be up to 32 characters long, and can consist of any displayable ASCII characters. 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 through queue az_queue, the job sent to the printer is "abcxyz". Instructions for setting up an LPD printer are different for different operating systems; refer to LPD Printing for details. Example. If you had an LPD printer 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 (Escape-E) at the beginning of each job. You could set this up as follows: 82 Chapter 4 HP Jetdirect Embedded Web Server (V.31.xx) ENWW
