Fedora 15 Network Printer Problems

[Bill]

Greetings. I've recently switched from Ubuntu to Fedora. So far I'm 
pleased, though I'm having real difficulty detecting my network printer 
(which worked "automagically" under Linux Mint 10). I've searched 
Google, the Fedora documentation, the Fedora Forums - everything I can 
think of to no avail.

I'm running Fedora 15 on a Dell XPS m1530 laptop (192.168.2.2), which is 
connected via modem/router to a network which includes my Dell Inspiron 
530 desktop (192.168.2.3), which is currently running Linux Mint 11. My 
HP Officejet 5610 all-in-one is connected to the desktop via usb cable.

I've used the Fedora 15 system-config-printer and cups browser interface 
to attempt to get it working. Firewall has been adjusted to allow 
connection. I installed hplip and have tried every driver available 
(including generic). I've tried every available ip address (http, https, 
ipp, socket and lpd) with various ports... no matter what I do the 
laptop will not detect the printer. (I even installed samba and tried 
connecting using a windows share.)

I can ping the desktop successfully, ssh, sshfs... but I can not find 
the printer.

Any suggestions will be appreciated.
