Item Description
Queue Type Processing instruction for the queue. Choose from these four queue types:
●
RAW No processing. Treats the data in a raw queue as a print job that is already
formatted in PCL, PostScript, or HP-GL/2, and sends it to the printer without
modification. (
Prepend or Append strings are added to the job in the appropriate
position.)
●
TEXT Carriage return added. 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) Uses auto-sensing to determine whether the print data is sent as
raw or text .
●
BINPS (Binary PostScript) Instructs the PostScript interpreter to interpret the print job
as Binary PostScript data.
Default Queue Name Queue name to use if the queue specified for a print job is unknown. By default, this is
AUTO .
String Name Name of a character string to use in the prepend/append queue table. Enter up to 32
alphanumeric characters. You can define up to eight character strings for use in LPD
queues.
Value Define the value for the associated string name used in the prepend/append queue table.
This value is sent to the printer before or after the print data (as appropriate).
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 165 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 165 .) After that, any
