Hi,

I am Anubhav from Wipro, India. I am interested in your specification of PSI
and I am subscribed to the mailing list as well.

I am sorry if I am not supposed to post in message on PSI to you this way,
however I assure you that once I know the protocol, I will stick to it.

Following is my comment on the Requirement Specs of PSI.

After reading the speicification document I see a note on page 17. This is
actually an issue "How does the mobile device know that it can use Model 3
instead of needing use model 2".

I see the following options:

a) Model 2 is one, wherein the mobile device is 
	1. more capable than in model 3 (hence is probably costlier)

b) Model 2 is one, wherein the print service is
	1. capable of handling lesser channels of simultaneous
communications than in model 3
	2. for some reason not able to talk to printer

Hence i feel that a mobile will need to take a decision to go in for 2/3
based on 

	1. Existing protocol support on the mobile itself
	2. May be depending of the level of support provided by the print
services
	3. Current load on the mobile/print service

However I am not sure about other issues that may be underlying this.

Best Regards,
Anubhav.
