I havea MBP 2.53 and a Samsung CLP-315 plugged directly into my Airport Extreme Base Station. Wireless network works great, Samsung drivers and software is installed on my Mac. Why is the printing flakey at best. When printing from Word or Excel (in OSX) sometimes it prints, and other times the printer light flashes once, and then nothing. In some cases I have to try printing 4 or 5 times before the thing finally goes. In all cases the printer queue appears, and everything seems to go fine, even when it is not actually printing. Also, in all cases, when I print, the little network printing box appears in the lower right (this may be samsung software at work) and it always says it cannot find the printer on the network, even when the printing does work. Does anyone have any advice about this. I do most of my computing upstairs, and the printer is in the basement. I would like to know that when I click print, it will work reliably. Right now, I bring my MBP to the basement and set it on my dryer. I just spam the print button until it works! Thanks for reading my novel!! Any help is appreciated.
