Re: [9fans] printing over usb

[James Chapman <james@cs.ioc.ee>]

Hi,

I 'solved' the problem by attaching the printer to my apple airport
express. Now I can print from plan9 using this neat trick I found
whilst digging in 9fans:

term% cat test.ps | telnet tcp!express.lan!9100
connected to tcp!express.lan!9100 on /net/tcp/2

I'd still like to be able to directly connect with usb. I will try
with native plan 9 instead of under vmware fusion and also try a
different printer to see if I get different results.

Is there some extra extra debugging I can enable to see what's going
on with the usb devices?

Best wishes,

James Chapman
