Canon mp600r wifi and airport express

Question

I have 2 airport express. One is a routeur (because there are an imac and an ibook)and is connected to dsl on internet. The others airport express is used to enlarge the wi-fi access network in the house.
i want to use the second airport express for my wifi printer, but without the usb port (because i can't scan from the printer,and the imac can't see the scan;i juste can print form the imac).
And i want to scan from the printer or from the imac.
what can i do?
thank you

Agreed, my MP600r works fine on my Airport network.
Problems may occur if you use WEP encryption.
One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
Though sometimes not even that works and the HEX key must be used regardless.
