Those are good choices as HP drivers have remained pretty constant (especially for the InkJet) over the years, but stay away from any serial port printers.
Using a LPT2USB device (http://www.lpt2usb.net/) allows access to newer USB connected printers; it does this externally and transparent to the Amiga. And of course with the Plipbox parallel Ethernet device you can get an A500 both online and have access to network printers.
Way cool, I just bought one after reading this. I have a few HP laser printers and I would think they should work.
