There has been a bit of grumbling recently about HP printer capability in one of our smallest prototyping Labs. We have a single GigE switch connecting a Windows 7 machine and a Dell/CentOS-6 machine. The CentOS machine also has connectivity via another network. Currently, only the Windows 7 machine has been setup for printing on our HP OfficeJet 8615. Our Samba effort on the CentOS system has not been successful so we use Cygwin and ftp to move files to the Windows 7 system for printing. Being able to print directly from the CentOS 6 system would be most convenient. Software supporting the HP OfficeJet Pro 8615 is apparently available as indicated in the links and other information below. We also see that hplip was apparently part of an installation or update performed on the CentOS 6 Dell machine at some point in time. http://sourceforge.net/projects/hplip/?source=typ_redirect http://hplipopensource.com/hplip-web/index.html The current version of the HPLIP solution is: 3.15.11.

Is there any significant possibility that printer setup or printer use on the CentOS 6 system will negatively impact printing functionality on the Windows 7 machine? Thanks in advance for any help or advice, and Happy New Year.
