Table 4-14 LPD Queues tab settings (continued) Item Description Character values can be 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 "\1B". If your string includes the back slash character itself, specify it as "\5C". Enter up to 240 characters in this field. 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. Instructions for setting up an LPD printer are different for different operating systems. See LPD printing on page 155 for details. Example To reset an LPD printer at the start of each print job, you can create a print queue named clear_printer that issues a PCL reset command (Escape-E) at the beginning of each job. First, set up the print queue: a. Name the string: Type reset_string into the String Name field in row 1. b. Define the string's value: Type "\1BE" (Escape-E) into the Value field in row 1. (Alternatively, you could type "\1B\45".) c. Name the queue: Type clear_printer into the Queue Name field in row 5. d. Set up the prepend string: Type reset_string into the Prepend String field in row 5. e. Leave the Append String field in row 5 blank. f. Set the queue type: Set the Queue Type field in row 5 to RAW. Then, set up the printer to use the queue, making sure to specify clear_printer when asked for a queue name. (For details about setting up the printer, see LPD printing on page 155.) After that, any print jobs sent to the printer either from the server or from a client computer that has set up that printer, includes a reset command at the beginning of the job. USB Settings If the HP Jetdirect external print server provides a USB connection to the network device (such as a USB printer), a link to USB configuration parameters is displayed.
