Question about HP Photosmart 7450 InkJet Printer

My printer is either asleep or it has died! It shows as "offline" but doesn't respond when I press the on switch, and doesn't respond to commands. I've tried plugging and unplugging it, switching it on and off etc. etc. The drivers are there all right. What can I do?

The Brother MFC-7840W printer was installed on a USB connection. The printer worked the previous week albeit not for all applications but at least for the Vista word program. Now it doesn't respond to...


Hi there!
You can check if the usb cable is connected directly & securely from printer to your computer. Once it's verified. The display of your printer should show the date/time.
Since the printer is displaying offline you can open Control Panel, go to Printers folder right click on the printer icon and select 'Use printer online' If you have pending documents right click on the printer icon and click on cancel documents.
Try checking for a duplicate copy of your printer driver or check which printer driver is selected as the default and has the status ready.
Right click on the printer driver that has a Ready status click on printing preferences and click on print a test page.
Hope this helps! Vikroks

Our Genicom Tally printer fails to keep settings. The model type is 6312. What could be the problem?


There may be a number of reasons for the 6312 failing to keep your settings, the first thing to identify would be that you have changed the settings on the printer and then saved these settings. If you do not save the settings to a menu / configuration they will be lost if the printer is powered off or receives a reset command.

Once you have made your settings changes, the settings can be saved in the following way;

Ensure the pritner is OFFLINE
Press Menu
Press Up Arrow until display shows Config Menu
Press Enter
Press Up Arrow until display shows Configurations
Press Enter
Press Up Arrow until display shows Save
Press Enter
Press Up Arrow until the Config Number Or Name appears that you want to save the settings to (Default is Confg 1)
Press Enter
Press Clear, to return to Offline mode.

If you save your settings you can then print a configuration report to see the values that have been saved, this can be done in the following way;

With the printer OFFLINE
Press the Menu key
Press any Arrow key until display shows Config Menu.
Press the Enter key.
Press any Arrow key until display shows Printer.
Press the Enter key.
Press any Arrow key until display shows Report.
Press the Enter key.
Press any Arrow key until display shows All Configs.
Press the Enter key and the configurations will be printed.

This should show your saved settings, try powerign th epritner off and back on again and again print the Congfig report to check the settings are retained.

If you find the settings appear to change when you print to the printer this will be caused by your print job, escape commands in the print job will take presidence over the printer menu settings.
You would need to check the host computer system to see what might be causing the problem; chack page size, fonts, ensure the correct printer driver is used etc on the system.

Follow the instructions on the LCD display, which will advise on removing and reinserting the paper.
After you have compleated the calibration place the pritner ONLINE to exit the menu.
And finally turn the printer power off, wait ten seconds and turn the printer power on again.

If the problem still exits you may need to repalce the lower tractors or the main logic board.

Does not respond when keys are pressed


Had the same problem, but printer on server showed on line.
Simple solution for us was to delete the printer on the workstation and add it again. After this, printer showed online again on our workstations.
