Printers mapping using CNAME with purpose of DR

Hello,

I am trying to achieve sort basic and manual level or DR by using DNS CNAME records to redirect to a print server.

Here is the scenario:

1. printserver1.domain.com and printserver2.domain.com.
2. Both have the same print queue object deployed. i.e. PQtest.
3. Created a CNAME [printserver.domain.com] on the DNS server pointing to printserver1.domain.com. I reduced the TTL to 5min.

Testing I have done:

1. Successfully connect to printer from \\ printserver.domain.com\PQtest.
2. Successfully printed job and can see the job on the spooler of printserver1.domain.com.
3. Go to DNS and change the target of the CNAME to printserver2.domain.com. Wait 5min for TTL to reset.
4. At the workstation where printer is mapped, I logout/in. Flush DNS cache. Try printing and does not work. The print job is still going toprintserver1.domain.com spooler.
5. If I ping or nslookup the CNAME printserver.domain.com I am directed to the correct IP for printserver2.domain.com.

It seems the previously mapped printer remember the path/ or original hostname behind the CNAME and does not update.

 My questions:

1. What could be causing this?
2. What am I doing wrong? Even in my approach...
3. Is there a different way to achieve what I am trying to do without a cluster environment?

Thank you
