I have the same problem with mine - first job usually prints but no go on the second one. It tells me the printer is "offline". In some cases I can't even power cycle normally. I have to unplug the back cord and plug it back in, then I can power back on.
I called Samsung today 1-800-726-7864 and was told the printer will need to be taken to a repair center for service. Wish I had better news.

    After much hard work and a trip to a repair shop where the ML-2525W worked fine on windows machines there, I discovered the following solution an an Apple web page involving deleting the printer from the preferences then re-adding it. This worked for me. Hope it works for you.

    If the print queue that you migrated from Mac OS X v10.5 has an issue, try these steps

    1. Ensure the printer is connected, has power, has ink / toner, paper, and no alerts on its built-in display.

    2. Network based printers should be on the same subnet; you shouldn't have to worry about this if your printer is on your home network.

    3. Use Software Update for the latest available updates.

    4. Delete the affected printer from Printer & Fax System Preferences, then re-add the printer.

    If you still have an issue, try these extra steps:

    1. Reset the printing system (see above). Then, add the printer again.

    2. If the issue persists, reset the printing system (see above). Download and install printer drivers from here. Then, add the printer again.

Samsung ML-2525W printer & Mac OS X 10.6

I think there are 6 ways (at least?) to connect this printer:
(1) Direct to Mac (or PC) via USB Cable (2) Direct to Mac (or PC) via Ethernet Crossover Cable (3) Ethernet to router/switch, with Mac/PC also via Ethernet to router/switch (4) Ethernet to router/switch, with Mac/PC via WiFi (802.11 wireless) (5) WiFi to router, with Mac/PC via Ethernet to router/switch (6) WiFi to router, with Mac/PC also via WiFi
As (1) should be simplest, tried this first. First document would print instantly and completely, next doc would hang in queue with unexpected msg, "Printer is offline." Only way to print 2nd doc was to power cycle (off-on) the printer. This problem occurred whether 2nd doc was sent to printer before or after 1st doc had printed. Tried 2nd USB cable, tried new driver, tried reinstalling printer; same problem. Spoke to both Samsung and Apple support, including both on a conference call; never got this to work and never clarified if problem was in printer hardware/software, driver, or something else.
Nothwithstanding USB problem, did succeed in modes (4) and (6), although custom wireless config needed since my network does not broadcast SSID and requires an encryption password. Also required different driver for wireless config (as opposed to USB).

Samsung ML-2510 Printer will not work with Macbook Pro - OS X

try to use the Generic drivers and not the Samsung ML driver for your model. In the drivers list type in GEN and it'll show up.

Samsung ML-2152W won't initialize

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

Driver for Samsung ML-1640 for WIN98SE

I got the same problem. It seems they did not develop specific drivers for win98se. However, I found that you can print using the drivers for the old Samsung ML-2510. Win98se drivers for that printer can still be downloaded from Samsung website. I've been using the 2510 drivers with the 1640 printer for a couple of months, and worked fine so far. It seems very little change in electronics from the 2510 to the 1640 model.
You need also Virtual Printer Port for USB from microsoft.
