There is modern printer support on the amiga as many have stated, you seem to just ignore the solutions given.
Whining about the hardware and os you bought doesn't do much good.
printing via network works fine, i have been doing it for many years on the amiga under os3.9 as well as 4.x. Before that i used a old hp5l for many years i picked up used for $39.
color lasers are dirt cheap now,and there are many new in the box ebay deals to be had even.
You can't cry that you bought a unsupported cut down windows printer. The logical thing to do would of been check what drivers were available before you bought that printer.
Amiga has always been a niche market compared to linux and windows and always will be.
printer models change as much as you change underwear(at i hope you do)and it is unrealistic to expect all of them to be supported.
You could always learn to write your own printer driver.
