While in Writer hitting ctl-p presents the print form, and you can select the various option, in calc ctl-p sends the current sheet to the printer. This is an inconsistency. I think calc should behave like writer. Anyway, I think the shortcut should have the same effect of the menu element (file-print), and in this case this doesn't happen.
For me this does not happen. What Linux distro and desktop environment are you using? Set back to UNCONFIRMED, if the bug is still happening. Win 7 64-bit Version: 4.4.0.0.alpha1+ Build ID: 8b21b5cbe78945b27525b4ce78ae3d981f90590f TinderBox: Win-x86@39, Branch:master, Time: 2014-11-06_03:55:51
