The printing from Calc is quite misorganised.

By default, the Calc prints all pages of all sheets.
Usually I need printing only from current sheet.

1, OOo has such option very far away, deep inside Options. User must check it,
and other time, when he wants to print whole document, must go to Options again
and uncheck..
The function of printing_from_current_sheet_only should be accessible more
flexible, maybe as suboption of Print button.

2, Even in actual design it dosent't work properly. If user enables the function
in Options, the print only accepts the option if he directly prints from Calc.
If he opens the Preview window first, the function is broken. Yes, there are all
pages from all sheets visible in Preview, so it's not big surprise that pressing
Print button prints again everything from all sheets.
This approach remains incorrect, however. User checked
"printing_from_current_sheet_only" and deserves the OOo's respect for his
choice! From user's point of view, OOo simply dosen't function correctly.

Moreover, such a behavior damages Preview function, because user dosen't use
Preview just for fun -he wants to check the overall design of document,
printability, correctness of formatting etc. The actual behavior de facto
disables the Preview function for him, because as soon as he opens Preview, the
Print no longer does what the user wants.

The right behavior?
1, Preview shouldn't have control over user set options. The user has priority.
If the user selects "printing_from_current_sheet_only", the Preview should obey
that.

2, User should be explicitely acknowledged that such option is selected when he
enters Preview and should have option to switch it on/off directly in Preview
window. Maybe some rollup-sellect-button "Only current sheet"/"All sheets"
should appear in Preview window. If there's "Only current sheet" visible in the
button, user knows what's happening. If user wants change the behavior, he
simply selects "All sheets" and again he knows what's going on.

In the Options, the function should act like this:
"By default, print from 1, All sheets 2, Current sheet only 3, Keep last setting"
