C4780 still says "printer off line" after troubleshooting

HP Photosmart C4780 Inkjet printer
Mac operating system
"printer off' line"
just moved and re-set up computer with same router....using printer wirelessly as before

Well, you did not say WHICH Mac operating system, so let's try this:
Reset the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.

Computer says printer Off line

computer says printer Off line, HP Office Jet 6500 E710n-z Class Driver I try to print and computer says printer is off-line. How do I get it back on-line?

Hi Michael74,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your Officejet 6500 e710n printer not being able to print. Try shutting if off, then pulling the power out of the back for about a minute. Plug it back in and turn it back on.
If that does not resolve the issue try the HP Print and Scan Doctor. The HP Print and Scan Doctor is a diagnostic tool that will help repair issues.
Please let me know how this goes.
Thanks.

Cannot print to canon MP160, dialog box says printer off line, but it is on line, OK printing with IE

I just installed the Canon MP160 printer. I downloaded the driver software from Canon version 12.1.4.0.(2/8/2008). I can print documents fine from Internet Explorer. When I go to print from Firefox the printer dialog box says the printer is "off line" and I get printer queue error messages. I can also print OK from windows. I have a PC 32 bit with Windows Vista.

I think your issue is that even though you have the latest 10.2.0 driver for 10.9, you added the printer using the previous v2.43 PPD. So open Print & Scan, remove the current printer for the iRC3380 and click the plus button to add again. After selecting IP > LPD and entering the IP address, ensure you select "Canon iR C2880/C3380" in the Use menu. Note that there is no mention of UFRII in the model name, as is the case with the previous UFR2 v2.43 driver.
Thanks for the suggestion. I did that this morning (see Step 1) and deleted the existing printer before re-adding a new printer and using the newly updated driver and printer description. Here's what I get:
You can see my model number is listed in there as is the the proprietary Canon UFRII language.
Once added, here's what happens next:
So it would appear, at this point, that the printer is installed and communicating and that I should be good to print.
Alas, I get the same error message I've been getting. back to square one.

C4795 printer off line

I have a HP Photosmart C4795
I have been using it wirelessly.
Today when attempting to print, I get the message "printer off line", "printer not connected"
I have been using it with my Mac (osX 10.7.5)
I did recently add a new wireless router to my home network (Mac Airport Express).
However I thought that the printer did not use the home wireless network, but rather it's own internal bluetooth.
Help?

Try these steps:
1. Restore Network Defaults on the printer (Wireless>Wireless Settings>Restore Network Defaults>Yes).
2. Rerun the Wireless Setup Wizard from the printer front panel to connect the printer to the router (Wireless>Wireless Settings>Wireless Setup Wizard).
3. Select your router from the list and enter the network password to connect the printer.
4. After the printer is connected, run the printer software on the Mac to discover the printer over the network connection.
5. Remove the old printer instance and Add the new printer using the + button in System Preferences>Print and Fax.

Red slide that says "Media off line."

When I work on a project and close it and then bring it back up again, the slides at the beginning of my project are gone and a red slide that says "media off line" in multiple languages comes up and my introductory slides are gone. Please help as this is getting really frustrating. Thank you.

What version of Premiere Elements are you using and on what computer operating system is it running?
The colorful media offline display indicate a disconnect between the source media that you imported into a project and the project file.
When you import source media into a project, all you have in the project are copies of the originals. The project needs to trace back to
the originals at the hard drive save location where they were when imported into the project. If you move, delete, or rename files and folders
that went into the project after you saved closed the project, you will get those media offline displays.
Another way to run into this type of issue is if you store your source media on an external hard drive and the external hard drive malfunctions, sometimes
changing drive letter.
The reconnects can be complicated and a major nuisance. They are typically done via making selections in the "Where is the file_____?" messages or using the Replace Footage feature.
Please review and consider and supply more details so that we can customize a reply for you to get to the solution.
Thank you.

Is the printer connected wirelessly?
Have you given it a fixed IP address, or is it receiving it via DHCP?

I do not know why you have declared the class as abstract. Abstract class must contain at least one abstract method.
In your code, there is no abstract method.
public Employee(String name, String address, String ssn,
            String id, double salary, double pay, String cvariable)
      name = EmpName;
      address = EmpAddress;
      ssn = EmpSsn;
      id = EmpEmployeeID;
      salary = EmpYearlySalary;
      pay = computePay;
      System.out.println("Constructor created");
     }The above code works only when you instantiate the object for the class. If it is abstract class, it will not work.
Abstract class cannot be instantiated.

Why can I not print from pages but can if I copy to text edit, I get "printer off line message " from pages ?

Why can I not print from pages but can if I copy to text edit, I get "printer off line message " from pages ? I use HP wireless printer .

Are you sure you have the right printer?
In UNIX/OSX printers are virtual links to devices and even with the same name can be trying to reach a printer via another network address, so it thinks it is another printer.

Ipad2: When I switch Wifi on, no available networks are listed. In the column on the left it still says Wifi 'off'.

Printing is landscape. Printing off line ok

When I printed before from the Internet, it always printed letter size. Now it is printing landscape. Off line it prints regular letter size. I need to know how to change it. I used about:config but although I marked the orientation to reset it is still printing landscape.

Hi there,
Looking at your link, I would say your browser is set to print each frame of the frameset separately rather than the complete frame. I've seen this with Windows but not with Mac's. Maybe have a look at the print settings and preferences of the browser/s.

if i unplug router and printer then connect router then printer all good again for about a day then gone again
cheers

Let’s try this.
Move the printer at least 3 feet away from the router.
1. Verify in the printer that 'Auto Off' is disabled. Use the Embedded Web Server (EWS) by going to the
    printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer
    Assistant, Printer Home Page (EWS).
2. Set a static IP in the printer (see step 6) outside the DHCP range of the router (check your manual).
In the router: (Refer to your router manual for information)
3. Use a fixed wireless channel like 1,6 or 11, never 'auto', try channel 1 first then the rest.
4. Set router to 20Mhz only, or 145Mbps depending on router.
5. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
6. Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your
   system now and helps with wireless connectivity (if you want to know why, search the web).
7. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same,
   they must be different for all bands, even for any Guest networks.
8. Save all settings. Power off both, wait 5 mins. Power on router wait 3 mins.
9. Power on printer and verify it reconnects to router.
Windows 7/8/8.1   Is Network Discovery on or off?
Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings.
Under Home or Work (current profile) \ Network Discovery.
Select "Turn on network discovery" and save changes.
Now try.

Hi,
During the process, it should ask you how to connect USB or wireless. Now, pull the USB cable out and run the setup from your computer again.
