Many thanks to all those who gave advice, either direct or through the list, regarding a low cost cost laser printer suitable for OSX 10.3.2.

After researching the various online suppliers (Officeworks, Harris, Harvey Norman etc etc) I finally purchased a Brother HL1430 laser printer for the excellent price of $299 (it is on "special"!) from Viking <http://www.vikingop.com.au/shop/catalog/sku.asp?ID=HL1430&LEVEL=SK&PR=Q72&FMID=6246201&SID=XFGGWGRC4WJH8GAK77RR987QME500439>.

It should be noted that purchases from Viking require an ABN number.
