  -  to print again and again till you get desirable results?
  -  to waste money on ink and paper for prints that going to be thrown away because they don’t look as you expect them to?
  -  that the same picture printed differently today then it was printed yesterday?
  -  of blocked shadow and highlights details even if the rest of the print looks to be all right?
  -  of problem of the “outside of colorspace colors", when your printer can’t  print some colors, so those looks very spotty, edgy, with obviously incorrect colors?

  -  that your printer doesn't give the quality that it is able to provide?
