I just tested certs from the the three following providers on iOS 9 (iPhone 6+) using the Pharos Print app without any issues.
- Starfield (at least available through GoDaddy)
Based on the certificate provided by this page <https://prtsrv03.tarleton.edu/myprintcenter/>, you are using an inCommon certificate which is not on the default list as you already know. Self-signed certificates would not work by default either since the issuer of the certificate is unknown to the iOS device. In the end, unless Apple adds inCommon to the trusted root certificates installed with iOS, you will either need to train people on how to install the certificate on each iOS device, or just get a new cert. It looks like the GeoTrust certs go for around $99 per year, and the Comodo certificates which go for around $50 may/should also work based on the them being listed.
Keep in mind that there are different types of certificates and a lot of times the increased cost is for the insurance that comes with protecting an e-commerce site. If you are not accepting credit cards, then you may be content with a cheaper cert that has less insurance. As for making sure what you get works, find out who the root authority is for the certificate you wish to purchase, and compare that to the list from Apple.
Hope this helps!

Just to add to this, we are running with InCommon certs and the iOS Pharos Print application works fine.
We just ran into this problem for iOS 9 devices. I had to reissue my COMODO certificate to get the SHA256 cert. Then I needed to install it on the Windows 2008 R2 server and the intermediary certificates (https://support.microsoft.com/en-us/kb/954755). Finally, I had to enable TLS 1.2 (https://support.quovadisglobal.com/kb/a433/how-to-enable-tls-1_2-on-windows-server-2008-r2.aspx) on my IIS server. It all works now and COMODO certs work.
Just to update...
We eventually ended up purchasing a SSL certificate from GoDaddy. Once we got those certificates installed, we no longer had certificate issues, but we had some network communication issues. As was stated above, we had to enable TLS 1.2 on our server and everything started working properly.
We ran into a similar issue and had to enable TLS 1.2 on our server in order for the latest version of Pharos Print v1.3 to work on iOS 9. However, we didn't have an issue with our InCommon certificate. At least for our InCommon cert it's signed by AddTrust External CA Root which is included in Apple's trusted root list.
