Epson ET-2760 wifi printer problems again...

All the latest updates to 64-current evidently killed my printer access.

I am still using slackbuilds from slackbuilds.org. Avahi from slackbuilds and cups frem Slackware were updated so these are the steps I did:

deleted mod_dnssd, nss-mdns, avahi, and libdaemon (all are slackbuilds).

deleted cups.

recompiled and reinstalled libdaemon (a dependancy of avahi)
recompiled and reinstalled avahi
recompiled and reinstalled mod_dnssd and nss-mdns

recompiled and reinstalled cups from slackware current source enabling avahi and dnssd

verified /etc/rc.d/rc.local had these lines:

# Start avahidaemon
if [ -x /etc/rc.d/rc.avahidaemon ]; then
/etc/rc.d/rc.avahidaemon start
fi
# Start avahidnsconfd
if [ -x /etc/rc.d/rc.avahidnsconfd ]; then
/etc/rc.d/rc.avahidnsconfd start
fi

verified that /etc/rc.d/rc.local had these lines:
# Stop avahidnsconfd
if [ -x /etc/rc.d/rc.avahidnsconfd ]; then
/etc/rc.d/rc.avahidnsconfd stop
fi
# Stop avahidaemon
if [ -x /etc/rc.d/rc.avahidaemon ]; then
/etc/rc.d/rc.avahidaemon stop
fi

verified that /etc/nsswitch.cinf had this line:
hosts: files mdns4_minimal [NOTFOUND=return] dns

I was finally able to print using my Asus desktop computer with a direct connection to the wifi router. But neither laptop using Slackware will see the wifi printer. The laptops are being networked strictly wifi only.

Running lpinfo --include-schemes dnssd -v shows nothing. Running the cups browser interface also shows no printers found.

I put an empty ssd in a laptop, installed Linux Mint and Mint found and setup my printer without even asking. Could be a possible security concern for some people.

Any help appreciated. I want to print via wifi on my slackware laptop computers again.
