I can print a test page from cups but not windows clients

I have an HP officejet Pro 8710. I have a Ubuntu 14.04 server that is running samba and uses CUPS as the print server. I installed hplip and all seems to work from cups admin. I can print a test page. I then try to install the printer on several windows machines. I add attempt to add the printer in control panel. I browse the network and my printer does not show up but when I browse to the server that has cups I see the icon for the printer and I select it. A window pops up asking me to install the driver. I install the driver but I can not print. I have run hp-check -t and it says error: 'gtk2-engines-pixbuf' package is missing/incompatible
error: 'xsane' package is missing/incompatible. I try to install both packages and aptitude says I have the most recent of both packages. It seems to me that samba is not talking to cups. Funny thing is this whole set up worked fine with my HP officejet pro 8500 A10. I did uninstall the older version of hplip before installing my new HP office jet 8710. Below is my hp-check -t. Note at the end I try to install the missing packages but it says I have the most recent. Thanks for the help

 hp-check -t

This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to
successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]
