Dear Carolyn, Thank you for your swift response. However when I went through the procedure it repeated responds :
The selected printer software is available from Apple. Click Add to download it and add this printer.
Having pressed Add Printer it goes through a seemingly optimistic procedure only to finally respond with
Setting up HP OfficeJet 5740 series [D4967B
The software for this printer is currently unavailable.
Please contact the printer's manufacturer for the latest software.
However I know it must be available as I have seen it on an Apple list as 3.3.2 for the OfficeJet 5740 [ P & S ]
and 5.1.7.1 for the Allin one Fax [ F ]
It would seem that the software has to initiate from Apple and not HP. All very frustrating and I have spent hours and hours without success, but thank you for trying. Regards Robert Scott
