May 11, 2015 9:35 AM in response to Linc Davisby gwfromlosangeles,The job is sent to the printer. I open the printer dialog box (? don't know what to call it) which shows "printing. Connected to printer" with the blue progress bar all the way across its window. And then NOTHING happens. I've done restarts, etc. but can't get it to print. (it is connected wireless)

ApplicationsLaunch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Select
/var/log ▹ cups ▹ error_log
from the hierarchical list on the left side of the Console window. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last failed printing attempt. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

Network Printer Troubleshooting
Ping printer: If you have the printers IP address open Terminal (Applications/Utilities) and at the prompt type: ping {printerIP}. You will get a reply or failure.
If you haven't done so already, try resetting the printing system.
