According to the Epic Level Handbook, in order to qualify for the Epic Spellcasting Feat, one must meet the following prerequisites:
Spellcraft 24 ranks, Knowledge (arcana) 24 ranks, ability to cast 9th-level arcane spells. OR Spellcraft 24 ranks, Knowledge (religion) 24 ranks, ability to cast 9th-level divine spells. OR Spellcraft 24 ranks, Knowledge (nature) 24 ranks, ability to cast 9th-level divine spells.
This is later confirmed in page 71:
Only spellcasters who have already mastered the ability to cast 9th-level spells can hope to tread the road of epic spellcasting.
However, in the section describing the Epic Ranger (p. 14, under the "Other Options" paragraph) it says:
If you like to cast spells, think about picking up Epic Spellcasting and one or more metamagic feats.
Why would they recommend Epic Spellcasting for a Ranger?
Unless I'm missing something, for an Epic Ranger (level 21) to have access to Epic Spellcasting he'd have to dual-class to a level 17 Wizard/Sorcerer/Cleric/Druid (that's 38 levels total!).
Am I missing something? Or is this some oversight that made it past proofreading before publishing? (copy/paste error maybe?)
