Redefined function call with proper parameters

[Kappuccino111]

The following error in make has been fixed @tillkamppeter @michaelrsweet

[tillkamppeter]

Have you tested building with both libcups2 and libcups3?

[Kappuccino111]

@tillkamppeter checked and compiled with both cups 2.4.x and the cups master branch

[Kappuccino111]

@tillkamppeter also updated install.md

[tillkamppeter]

Note that the CUPS master branch is NOT libcups3, the CUPS master branch is CUPS 2.5.x.

To compile with libcups3, install libcups3 (does not overwrite anything of installed CUPS 2.5.x, then, in libcupsfilters and libppd do

make distclean
./configure
make
sudo make install

Check the output of ./configure to see whether it really selected libcups3 and not libcups2.

Compiled with libcups 3 .... works perfectly @tillkamppeter
