queue:    Papercut-Default
source:   /home/rsnel/tmp/reseach/2324-D.antwWIHM.pdf
media:    media=A4 pinned on every job
PPD:      the server's default Follow-Me.ppd, no option-mapping backend
answers:  l = 2-sided long edge; s = 2-sided short edge;
          1 = 1-sided; other text = unknown; empty = not checked

test 1: baseline - no duplex option
  why:      control: is the queue default simplex?
  expect:   one-sided (queue default)
  lp:       lp -d Papercut-Default -o media=A4 /tmp/duplex-tests-ukr8_p0j/test1.pdf
  job:      Papercut-Default-71
  display:  one-sided
  note:     (none)

test 2: sides=two-sided-long-edge
  why:      standard IPP attribute
  expect:   long edge (normal duplex)
  lp:       lp -d Papercut-Default -o media=A4 -o sides=two-sided-long-edge /tmp/duplex-tests-ukr8_p0j/test2.pdf
  job:      Papercut-Default-72
  display:  long-edge
  note:     (none)

test 3: sides=two-sided-short-edge
  why:      standard IPP attribute, other binding
  expect:   short edge
  lp:       lp -d Papercut-Default -o media=A4 -o sides=two-sided-short-edge /tmp/duplex-tests-ukr8_p0j/test3.pdf
  job:      Papercut-Default-73
  display:  short-edge
  note:     (none)

test 4: Duplex=DuplexNoTumble
  why:      generic PPD option name
  expect:   long edge only if the PPD name is honoured, else the default
  lp:       lp -d Papercut-Default -o media=A4 -o Duplex=DuplexNoTumble /tmp/duplex-tests-ukr8_p0j/test4.pdf
  job:      Papercut-Default-74
  display:  one-sided
  note:     (none)

test 5: Duplex=DuplexTumble
  why:      generic PPD option name
  expect:   short edge only if the PPD name is honoured, else the default
  lp:       lp -d Papercut-Default -o media=A4 -o Duplex=DuplexTumble /tmp/duplex-tests-ukr8_p0j/test5.pdf
  job:      Papercut-Default-75
  display:  one-sided
  note:     (none)

test 6: Duplex=None
  why:      PPD name, one-sided control
  expect:   one-sided
  lp:       lp -d Papercut-Default -o media=A4 -o Duplex=None /tmp/duplex-tests-ukr8_p0j/test6.pdf
  job:      Papercut-Default-76
  display:  one-sided
  note:     (none)

test 7: KMDuplex=2Sided
  why:      Konica Minolta PPD option name
  expect:   long edge only if the vendor PPD name is honoured, else the default
  lp:       lp -d Papercut-Default -o media=A4 -o KMDuplex=2Sided /tmp/duplex-tests-ukr8_p0j/test7.pdf
  job:      Papercut-Default-77
  display:  one-sided
  note:     (none)

test 8: sides=two-sided-long-edge + Duplex=DuplexTumble
  why:      conflict precedence
  expect:   long edge if the IPP name wins, short edge if the PPD name wins
  lp:       lp -d Papercut-Default -o media=A4 -o sides=two-sided-long-edge -o Duplex=DuplexTumble /tmp/duplex-tests-ukr8_p0j/test8.pdf
  job:      Papercut-Default-78
  display:  long-edge
  note:     (none)
