Description of problem:

Various numerical job options to 'lp' can have, in fact, decimal
fractional parts.   This is even important when one is trying to
print text files with as big fonts as feasible and there is
a substantial difference between things like 'cpi=9.25' and 'lpi=5.5'
and their integer parts.

Despite of that current 'system-config-printer' does not allow to
enter values like the above.  Actually the situation is more curious.
If you will edit /etc/cups/printers.conf directly and use fractions
there then the next time 'system-config-printer' will display those
correctly, with save them after some modifications were made, and
will even allow to change fractional parts as long as a decimal
'.' is around.  The moment one will erase that character fractions
are becoming inacceptable.

'system-config-printer' from FC6 suffers from the same affliction
and this is regress from FC5 where putting fractional values was not
an issue at all and those parameters were actually correctly passed
to printing.

An impact of this bug is currently minimized due to bug 224645
which means that it really does not matter what is accepted or not
as whatever is typed in options values seems to be summarily
ignored; well, at least when printing text files.
