If the printer is connected to the Mini via USB then you would need an application like Printopia to allow printing from the iPhone. Note that the iPhone would need to be using iOS 4.2.
If the printer is connected to Linksys using wireless then you may still need an application like Printopia, as the following document indicates that the L7590 does not support AirPrint.
Thanks! Printopia works great! I downloaded the trial for free, but will probably spring for the $9.95 when it runs out in 10 days. I'm sure there is a way to print to my HP directly through my wifi network, but it probably isn't as easy or intuitive as Printopia.
If I may, a query about printing from iPhone 3GS using OS 4.2.1, but to Canon printers.
I have two Canon printers available -
- MX860 USB connected to AirPort Express base station serving my MacBook, Windows 7 PC using Bonjour, and another computer using Ubuntu 10.4LTS. (All work well, although the Win 7 PC is sometimes slow, triggering a "printer not responding" message, but that is of no real concern to me);
- iP100 fitted with Bluetooth BU-30.
My preference is to use the iP100...
I've googled and found free and paid applications, but need guidance as to the best way forward. If that is possible...
To print to the iP100 via Bluetooth you would need to look at using an application like [Printopia|http://www.ecamm.com/mac/printopia>. This would need to be installed on the MacBook so that it can 'share' the printer to the iPhone.
Now I'm not sure how well this will work. I've used the demo version of the Printopia to print to USB and networked connected printers but not Bluetooth. It worked fine for my iP4 and iPad but I have no need for the product and my demo has now expired. In theory it should work but you will need to test to be sure. At least there is a demo of Printopia available so you can test before buying.
