RFC 2569         Mapping between LPD and IPP Protocols        April 1999


   Note: 'L' has special meaning when it is omitted. If 'J' is omitted,
   some undefined behavior occurs with respect to the banner page.

6.3 Required Document Functions

   The mapper SHALL include one set of the following LPD functions with
   each document, and they SHALL have the specified values. For each
   document, the order of the functions SHALL be 'f', 'U' and then 'N',
   where 'f' is replicated once for each copy.

   IPP attribute                      LPD function

   name        value                  name value  description

   document-   'application/octet-    f    fff    Print formatted file
   format      stream' or
               'application/PostScript'
   copies      c                                  replicate 'f' 'c'
                                                  times
   none                               U    fff    Unlink data file
   document-   n                      N    n      Name of source file
   name

   Note: the value 'fff' of the 'f' and 'U' functions is the name of the
   data file as transferred, e.g. "dfA123woden".

   Note: the mapper SHALL not send the 'o' function

   ISSUE: should we register DVI, troff or ditroff?

   If the mapper receives no "ipp-attribute-fidelitybest-effort" or it
   has a value of false, then the mapper SHALL reject the job if it
   specifies attributes or attribute values that are not among those
   supported in the above tables.

   Below is an example of the minimal control file for a job with three
   copies of two files 'foo' and 'bar':

      H tiger
      P jones
      f dfA123woden
      f dfA123woden
      f dfA123woden
      U dfA123woden
      N foo
      f dfB123woden
      f dfB123woden
      f dfB123woden

7. Security Considerations

   There are no security issues beyond those covered in the IPP Encoding
   and Transport document [RFC2565], the IPP model document [RFC2566]
   and the LPD document [RFC1179].

10. Appendix A: ABNF Syntax for response of Send-queue-state (short)

   The syntax in ABNF for the response to the LPD command 'send-queue-
   state (long)' is:

    status-response = empty-queue / nonempty-queue
    empty-queue = "no-entries" LF
    nonempty-queue = printer-status LF heading LF *(job LF)
    printer-status =  OK-status / error-status
    OK-status = printer-name SP "ready and printing" LF
    error-status = < implementation dependent status information >
    heading = "Rank" 3SP "Owner" 6SP "Job" 13SP "Files"
                    23SP "Total Size" LF
                       ; the column headings and their values below begin
    at the columns
                       ; 1, 8, 19, 35 and 63
    job = rank *SP owner *SP job *SP files *SP total-size "bytes"
                      ; jobs are in order of oldest to newest
    rank = "active" / "1st" / "2nd" / "3rd" / integer "th"
                      ; job that is printing is "active"
                      ; other values show position in the queue
    owner = <user name of person who submitted the job>
    job = 1*3DIGIT   ; job-number
    files = <file name> *( "," <file name>) ; truncated to 24 characters
    total-size = 1*DIGIT  ; combined size in bytes of all documents

11. Appendix B: ABNF Syntax for response of Send-queue-state (long)

   The syntax in ABNF for the response to the LPD command 'send-queue-
   state (long)' is:

    status-response = empty-queue / nonempty-queue
    empty-queue = "no-entries" LF
    nonempty-queue = printer-status LF  *job
    printer-status =  OK-status / error-status
    OK-status = printer-name SP "ready and printing" LF
    error-status = < implementation dependent status information >
    job = LF line-1 LF line-2 LF
    line-1 = owner ":" SP rank 1*SP "[job" job SP host "]"
    line-2 =  file-name 1*SP document-size "bytes"
          ; jobs are in order of oldest to newest
    rank = "active" / "1st" / "2nd" / "3rd" / integer "th"
            ; job that is printing is "active"
            ; other values show position in the queue
    owner = <user name of person who submitted the job>
    job = 1*3DIGIT
    file-name = [ 1*DIGIT  "copies of" SP ] <file name>
                  ; truncated to 24 characters
    document-size = 1*DIGIT  ;size of single copy of the document.

12. Appendix C: Unsupported LPD functions

   The follow LPD functions have no IPP equivalent. The LPD-to-IPP
   mapper ignores them and the IPP-to-LPD mapper does not send them.

    LPD command
    name  description

    C     Class for banner page
    I     Indent Printing
    H     Host of client
    M     Mail when printed
    S     Symbolic link data
    T     Title for pr
    W     Width of output
    1     troff R font
    2     troff I font
    3     troff B font
    4     troff S font

   The follow LPD functions specify document-formats which have no IPP
   equivalent, unless someone registers them. The LPD-to-IPP mapper
   rejects jobs that request such a document format, and the IPP-to-LPD
   mapper does not send them.

    LPD command
    name   description

    c      Plot CIF file
    d      Print DVI file
    g      Plot file
    k      reserved for Kerberized clients and servers
    n      Print ditroff output file
    p      Print file with 'pr' format
    r      File to print with FORTRAN carriage control
    t      Print troff output file
    v      Print raster file
    z      reserved for future use with the Palladium
           print system
