How to use HP 3510 wirelessly in Slacko?

[RichK]

I installed HP 3510 with USB connection in Slacko 5.3.1 (from Multiboot USB) on laptop. It works when connected locally. But wireless install of the printer is not working.

Used App Sockets and HP/JetDirect connection to get:
Driver: HP Deskjet 3550, hpcups 3.12.4 (color, 2-sided printing)
Connection: socket://192.168.1.11

Also tried 3500 driver.

When I print test page, the LCD display on printer wakes up but nothing prints. Slacko shows the job completed.

I'm new to Linux from Windows land and loving it. But haven't been able to find a fix for this issue.
Any help is appreciated.
