Which Cups printer driver to print various formats

[dougm226]

Have HP LaserJet Pro MFP M521 in a RHEL 7 env.
I can successfully print to them but am struggling to find a driver that will allow me to:
Print various fmt files (pcl,txt,pdf,xls,etc)
Allow sending lp options for landscape, scaling and maybe font selection

So far have tried the proper PS driver, as well as several pcl drivers. (Both HP branded and generic) If I lp a file to the device when defined as ps or pcl, the binary pcl gets interpreted and then does not do the graphics properly. Oddly, defined as a generic txt printer works and graphics come thru. Unfortunately the txt driver does not allow the extra lp options support I am looking for and I suspect would not work for pdf either.

Hoping for a generic all-in-one driver that can recognize jobs streams and handle accordingly.
