Printer sharing with 2 machines using CUPS and router?

Wife and I each have machines running Slackware. We use a Linksys router to
share the SBC DSL modem via DHCP/PPPoE.

She has a parallel color deskjet printer under CUPS attached to her laptop. I
have an ancient parallel HP LaserJet under CUPS attached to my tower.

Each machine runs CUPS.

We don't need to share files but I'd like to be able to use her color printer
from time to time. Is this possible? I've been all over the net looking for
how to do this and all I can find is multiple printers under one CUPS
'server'. I know I have to change one of the the cupsd.conf on one (both?) of
the machines, but I'm lost. Do I need to "add" a printer on my machine via
localhost:631?

Can anyone point me in the right direction?

I don't have personal experience of slackware and how it sets up, but
generally CUPS will handle all the queue assignments for you and you need
tell it only about the paramaters for the printer type, driver, resolution
and location. Suse handles this quite neatly through the YAST
configuration tool. It may be that Slackware has something similar.

Yes.

Ensure, that your firewall/Router allows to use port 631 in the local net.
Perhaps you have to open port 631 in iptables.
Then select remote printer in cupsconfig / Printing Manager, fill the
dialog. The URI is IPP://$RemoteHostname:631/printers/$PrinterName.

The Linksys router lets me do port forwarding but I don't know which computer
to forward to .... mine or my wifes?

We're not using a software firewall.

I did this but it does not see my wife's printer on her server. She has a
specific driver that I don't have because the 712C is a piece of crap and
does not use the 'standard' driver.

Are you sure I don't have to change her cupsd.conf file? Or mine?

I assume you have the obvious household network topology of two hosts
on a single ethernet, with the router as the third host as well as
being both the hub/switch and the lone router on the local network.

For the love of dog do not adjust your firewall/forwarding/router
settings to let printer service through, as another poster suggested.

Yes. Turn on the broadcast advertising feature in cups on both
machines. Then all cups clients will be able to see any cups printers
on your network.

The settings are in /etc/cups/cupsd.conf (possibly located in /etc or
elsewhere). There should be comments in that file making it somewhat
clear what to do. Edit this file, then restart the cups service, all
on both sides. Key settings will include:

Browsing On
BrowseProtocols cups
BrowseAddress @LOCAL
BrowseAllow All
BrowseInterval 30

Thanks for the help. I got it to work. The "BrowseAllow" All is the key.
