The kind of work you describe can easily be done on an AmiagOS 4.1 machine.
I use Wordworth 7 for wordprocessing, poster / flyer creation. Printing to postscrit them converting to PDF with Ghostscript.
(my PDFMaker script isavailable here http://www.broad.ology.org.uk/docs/a...imple_App.html
, realy ought to split that out of the tutorial an upload it to os4depot)
I use SketchBlock and ImageFX for graphics creation, saving the results inot 3 formats native (.skprj for further editing) , .ps for inclusing in Wordworth docs, and 24bit ilbm for previewing in wordworth (need imagefx for that). And ofcourse jpeg png etc for websueage where required.
Printing wise I have a HP laserjet Pro 200 color M251n which takes postscript data direct. This is important, don;t get any new printer that doesn't support postscript. You want a lasre for quality anyway, and all the other will lack somewhere in the driver chain.
