This would normally require a WiFi connection which the Storm is famously without. The only other way you could accomplish this is with Bluetooth if your printer supports it, or by printing over the internet...for this you would need someone to develop an application that would send your print job over the internet to your printer.
To my knowledge there is no software solution that will permit you to print to a printer at this time.
I will have to check for bluetooth connectivity.
My whole house is on a wireless network. Laptop, ps3, psp, printer, and hopefully one day my crackberry as it is what i dedicate the most time to!
