ML-191x 252x Series. When I print, why doesn't it go into queue?

Install the printer/scanner software and use the menu system.

Hi guys, The solutionto your problem is simple, just press the button just above the on/off buttonto print out the start of the printer. Make sure to see the "Toner Remaining" .

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.

Try purging the 3 pending print jobs then try to print again. Go to Printer and Faxes on XP, then right click on your printer icon then select purge print jobs. Or double-click on the printer icon on your system tray (lower right hand of the screen) then click on the pending print jobs then purge it. Then try to print again.

maybe..online error usually is a communications issue..you might want to isolate the printer from the computer power line, if that's an issue.
