That's a bug.

Allright. No PNG support. That means you can't print because that
relies on an intermediate PNG file. You shouldn't have been able to
even select scanning to printer in that case.

You don't mention the iscan version you use, but I am assuming you are
using a self-built version of 2.12.0 or later. The following is based
on that assumption.

It's a problem with both really. You can work around this by running
iscan from the command-line as follows:
That way, iscan will look there first and it should pick up on your
libpng.so. The default library search path on SUSE puts the lib64
directories towards the end so iscan looks at /usr/lib/libpng12.so
first. That is a 32-bit library which doesn't jive with a 64-bit
iscan. Unfortunately, iscan then gives up looking for PNG libs.
The same story goes for JPEG and TIFF libraries.

If you file a bug report with SUSE, let me know (so I can follow it
and don't have to do it myself). You should probably file it against
the glibc package.
