I have a 7820N on a Snow Leopard Mac system. The printer will work fine for a while and then I get "Printer Offline" messages and no printing. I try shutting down the 7820 and restarting, which sometimes works and other times not. I fiddle with the printer panel in OS. No matter what I do the problem will persist. Then suddenly, in hours or days, it goes away for a while. Please HELP!! Thank you.

download the osx10.5 printer driver

or if you can find it online the correct printer driver for osx10.6

Yes you need to download the drivers from samsung site in internet, there are three drivers availabl for mac, one for your system snow leopard, you need to download the printer and the scanner driver and the samsung DR. Printer part!

Hi,
Shortly after the world started upgrading to Snow Leopard, reports began emerging that many Hewlett-Packard printers were incompatible with the upgrade. So, you can wait till you get the updated driver which is compatible with Mac Snow leopard.
Good Luck!

The first thing that you need to do is to verify if your Olympus P-440 is if it's supported by Mac OSX 10.6.x (Snow Leopard). If yes, make sure that you've installed the correct driver for Snow Leopard.

You may check the link below:

This link contains a driver for Mac OSX. I assume that this driver will work with all OSX (starting from Tiger to Snow Leopard). If this driver will not help, you may need to contact the manufacturer, and verify the system requirements of your printer.

Thank you and good luck!

The drivers should be packaged into snow leopard. This printer is listed as a supported printer for Snow Leopard.

this link will walk you through the process

This is the best solution for that problem and works perfectly...

Just posted a solution to this - but in case you haven't seen it, the story is that there is a note on the Epson support website for the SX515W saying that there is a known bug with the TCP/IP on Snow Leopard (not sure whether this is the same version as your Mac OS - but the problem sounds identical). Anyway, they suggest as an interim measure that you install a generic Bonjour driver (there are instrcutions on how to do this). Only thing I would add is that you will see that the new driver effectively shown up as an additional printer on your Mac. I found that you have to reassign this new printer as the default printer before it will work. Hope this helps. As I wrote before, I personally think that it iw pretty poor of Epson not to have this problem sorted by now - Snow Leopard has been out a long time now...

Had the same problem. If you go onto the Epson support page for the SX515W, you will see that there is a note saying that there is a known bug with the TCP/IP issue with Snow Leopard.

I am working on one of these right now for a customer. It is doing nearly the same thing. I am 99% sure it has bad capacitors in the power supply. I have removed the power supply board and found swelled and leaking caps. I will get them replaced to verify, but I am positive that is the solution. Your printer will need either a new/repaired power supply or have your existing power supply board repaired.
Good Luck

There are apparently incompatibilities between some Xerox drivers and the security-improved Snow Leopard. It seems that many pieces of software (and drivers) relied on not-so-clean techniques to cut corners while operating. These techniques are no longer allowed by Snow Leopard (the same problem afflicts XP SP3, Vista and Seven).

This article lists several problems, explanation and (perhaps) fixes:

Meanwhile, Apple is working to some workarounds too (there is an update linked in the article which may be of interest to you).
