Description

Y

Y

5.1 01-Print any waiting jobs

Starts the printing process if it is not already running.

Y

Y

5.2 02-Receive a printer job

Controlled by a second level of commands. LPD gets commands by sending them over the same connection.

Y

Y

5.3 03-Send queue state (short)

If user name, job number, or both are supplied, only those jobs for those users or with those job numbers will be sent. Response is an ASCII stream that describes the printer queue.

Y

Y

5.4 04-Send queue state (long)

If user name, job number, or both are supplied, only those jobs for those users or with those job numbers will be sent. Response is an ASCII stream that describes the printer queue.

Y

Y

5.5 05-Remove jobs

Deletes print jobs from the specified queue. If only the agent (user name making request) is given, deletes the currently active job. Can only delete a job that is not owned by the user if agent is “root.”  Only “root” agent can delete jobs by user name.

Y

Y

6.1 01-Abort job

Removes files created during this “receive job” command.

Y

Y

6.2 02-Receive control file

Control file is ASCII stream. Ends of lines are ASCII LF. Total number of bytes sent as first operand. Name of control file sent as second. It should start with ASCII “cfA” followed by 3-digit job number followed by host name that constructed the control file.

Y

Y

6.3 03-Receive data file

First operand is total number of bytes in the stream or zero. Name of file should start with ASCII “dfA” (might change to dfB, dfC, etc.) followed by 3-digit job number followed by host name that constructed the file. In the Barr product, LPR does not send a zero byte count and LPD will not support a zero byte count.

Y

Y

6.4 04-Receive control file first

Allows you to send a control file followed by multiple data files when you receive files to the print spool, which means you can print multiple copies of a file.

Y

Y

6.5 05-Receive data file with unspecified length

Allows the host to send a data file without specifying the length. The host must send the control file first because the end of file is acknowledged when the host closes the connection.

Y

Y

8.1 C-Class for banner page

Sets the class name to print on the banner page. If name is omitted, name of host on which file is printed will be used. Class operand is used to display the host from which the printing job originated.

Y

Y

8.2 H-Host name

Specifies the name of the host to be treated as the source of the print job. Command must be included in the control file.

Y/N

Y*

8.3 I-Indent printing

Specifies number of spaces to indent when the file is printed with the “f” option (only valid option).

Y

Y

8.4 J-Job name for banner page

Sets the job name to print on the banner page. It can be omitted. Conventionally used to display the name of the file or files “printed.” Ignored unless the print banner command code “l” is also used.

Y

Y

8.5 L-Print banner page

Causes banner page to print. User name can be omitted. Class for banner page “c” and job name for banner page “j” must precede this command in the control file to be effective.

Y/N

Y*

8.6 M-Mail when printed

Causes mail to be sent to the user at the host specified by the “h” entry when printing operation ends.

Y

Y

8.7 N-Name of source file

Specifies the name of the file from which the data file was constructed. Returned on a query and used to print with the “p” command code when no title is given.

Y

Y

8.8 P-User identification

Specifies the user identification of the entity requesting the printing job. Must be included in the control file.

N

N

8.9 S-Symbolic link data

Used to record symbolic link data on a UNIX system so changing a file’s directory entry after a file is printed will not print the new file. Ignored if the data file is not symbolically linked.

Y

Y

8.10 T-Title for pr

Provides a title for a file to be printed with the “p” command code. Ignored by other printing commands.

Y

Y

8.11 U-Unlink data file

Indicates that the specified file is no longer needed. Only use with data files.

Y/N

Y*

8.12 W-Width of output

Limits the output to the specified number of columns for the “f”, “l” and “p” command codes. Ignored for other output generating commands.

N

Y*

8.13 1-troff R font

Specifies the file name for the troff R font (font printed with Times Roman by default).

N

Y*

8.14 2-troff I font

Specifies the file name for the troff I font (font printed with Times Italic by default).

N

Y*

8.15 3-troff B font

Specifies the file name for the troff B font (font printed with Times Bold by default).

N

Y*

8.16 4-troff S font

Specifies the file name for the troff S font (font printed with Special Mathematical font by default).

N

Y*

8.17 X-extended print option

Specifies print option  extensions.

Y/N

Y*

9.1 c-Plot CIF file

Causes data file to be plotted and treats the data as CIF (CalTech Intermediate Form) graphics language.

Y/N

Y*

9.2 d-Print DVI file

Causes data file to be printed and treats the data as DVI (TeX output).

Y/N

Y*

9.3 f-Print formatted file

Causes data file to be printed as plain text file with page breaks. Discards all ASCII characters except HT, CR, FF, LF, and BS.

Y/N

Y*

9.4 g-Plot file

Causes data file to be plotted and treats data as output from Berkeley UNIX plot library.

Y

Y*

9.5 k-Reserved for Kerberized LPR clients and servers

Y

Y

9.6 l-Print file leaving control characters

Causes specified data file to be printed without filtering the control characters (which the “f” command code does).

Y/N

Y*

9.7 n-Print ditroff output file

Prints the data file and treats data as ditroff output.

Y/N

Y*

9.8 p-Print file with “pr” format

Causes data file to be printed with heading, page numbers and pagination. Heading should include date/time printing started, title, and page number identifier followed by page number. Title is name of file specified with “n” command code unless the “t” (title) command code was used. After page of text prints, starts with new page and new page number (no way to specify length of page).

Y

Y

9.9 r-File to print with FORTRAN carriage control

Causes data file to be printed. Interprets column of each line as FORTRAN carriage control (blank, 1, 0, +). Most FORTRAN programmers expect - (triple space) to work too.

Y*

9.10 t-Print troff output file

Prints data file as Graphic Systems C/A/T phototypesetter input (standard output of UNIX troff command.

Y
