Just started getting this when trying to install iprint printers from
my oes2sp3 box (runs on sles10sp4). Strange thing is, I have a couple
machines that printers install just fine.

The vast majority of printers will not install, when I try, I get the

ErrorCode: 5

Error message: The SSL connection encountered an I/O error.

Error group: SSL
Error code: 5

I have secure printing enabled on my printers so not just anybody can
print to any printer.
