Referring to our earlier article Mac OS X Panther, Solving Network Printing Over Airport Express Networks, the release of Airport Express Firmware v.6.2 has enabled greater support for previously unsupported printers.
Its now safe to try uploading the latest Airport Express Firmware v.6.2 onto your Airport Express and expect support for your printer which faced driver issues in Airport Express Firmware v.6.0 thru v.6.1.1. Give it a go and in any that you find that your printer does not function, you can always revert to the earlier Airport Express Firmware v.6.0 from our Downloads section and upload it over the newer version.
