So rather than employ people who either new how to install printers on windows or could work it out (follow the prompts in the wizard) for themselves we employed people who would happily follow the step by step instructions in our documentation.
Everything fell apart when we migrated to Windows XP, where the instructions no longer worked, the screenshots were out of date and those support personnel who used to rely on all the documentation for step by step on how to install printers were left scratching their heads.
Documentation is great, but its main aim should be to detail the outcome required, why it's required and any unique situations that the reader should be aware of.
Some bureaucracy are random stops, others are brakes.
