HOW DO YOU MAKE AN EXACT DUPLICATOR ON THIS DEVICE

If the LCD light on your Zenith CD/DVD duplicator is on but it is not showing as "ready," it is possible that there is an issue with the duplicator's internal components or settings. Here are a few troubleshooting steps you can take to try and resolve the issue: Check the disc trays: Make sure that all of the disc trays are closed properly and that there are no discs stuck inside the duplicator. If a tray is open or a disc is stuck, the duplicator will not be able to operate properly. Check the power source: Make sure that the duplicator is plugged into a working power source and that the power cable is securely connected to the duplicator. If the power source is not providing enough power, the duplicator may not be able to operate. Check the settings: Check the duplicator's settings to ensure that it is set up correctly for the type of disc you are trying to duplicate. For example, if you are trying to duplicate a DVD, make sure that the duplicator is set to duplicate DVDs and not CDs. Reset the duplicator: Try resetting the duplicator by unplugging it from the power source for a few minutes, then plugging it back in and turning it on. This can sometimes resolve minor issues with the duplicator's internal components. If none of these steps resolve the issue, it is possible that there is a more serious issue with the duplicator's hardware or software. In this case, it may be best to contact Zenith customer support or a professional technician for further assistance.

Specify: what sort of computer are you using? PC? Mac? Android?
What OS version? Windows 7, 8, 10? Mac version?
What kind of output connectors are on your device? VGA, HDMI, lightning port, DVI, other?
What kind of input connectors are on your second monitor?
What are you trying to do with the second monitor? Simultaneously see a second app beside your other monitor (extend)? See the same exact image as the other monitor (duplicate)? Send the same/duplicate image (duplicate screen) to a projector, or send a different image to it (extend)?
If you can answer these questions, your inquiry will be easy to solve. Without that info? Hard to answer.

Start with photos and music files: if there are duplicates - make SURE they are exact duplicates (name/file size/R click-quicklook). You can get an external hard drive cheaply (http://www.amazon.com/s/ref=nb_sb_ss_c_0_19?url=search-alias%3Daps&field-keywords=external+hard+drive&sprefix=external+hard+drive%2Caps%2C166) and move important info. If you are unsure of your knowledge - ask friends!

To remove duplicate contacts from the Yahoo! Mail address book:

• Follow the Contacts link in Yahoo! Mail.

Using Merge all EXACT on the duplicates list, you can quickly eliminate any dupes that are precise copies without differences.

This is a problem that always plagued me too. I think you will never be able to get exact scaling or colours because the secret service is afraid of duplicating important documents exactly. Like those vip star badges they like to sport. If you could duplicate one of those you might say you are one too. Should have scale settings within the printer software previously installed. But it will never be exactly right unless you are rich and powerful and buy expensive stuff.

You can have a try Leawo Tunes Cleaner. Just follow below steps. If you still have issues or have a massive music library in iTunes or other music folders that requires a more powerful and less time-consuming option, the third-party software like Leawo Tunes Cleaner can help you. It can not only automatically clean up duplicate songs in iTunes, but also automatically delete duplicate songs in other music folders. If you want to automatically remove duplicates in iTunes, the automatic duplicate remover might have the answer for you.
1. After kicking off Leawo Tunes Cleaner, click the "Clean-up Duplicate" entry. The program provides 2 duplicate scanning modes: Quick Scan mode and Deep Scan mode. Select one of them to scan duplicate songs.
2. You could delete duplicates in iTunes music library by directly clicking "Scan iTunes" button or click "Add" button to load music files for duplicates removing.
3. After loading source music files, click the "Scan" button on the upper-right corner to start scanning duplicates. The program would display all duplicates clearly and suggest what to remove. You could decide which duplicates to delete by checking them and then click the "Remove" button to remove duplicate songs.

The printer shouldn't print the same barcode twice. As long as the data is exactly the same, and the supplies are exactly the same, these two printers should be acting the same.

Are you using a 3rd party software application or driver? If so, you may need to contact them to help you adjust the issue, but longoftheshort, if the printer details are exact, like above, then the printer is duplicating, likely, because it is being told to do it. Since the printer cannot arbitrarily reprint a label, it must be told to do it. That is either done through data, or it is done because it didn't finish the job on the previous label and may do it on the followup label.

my duplicator keeps on giving this info ''fatal error'' whenever i put it ON kindly assist asap

I would use the "Delete iCal Duplicates" AppleScript here:
http://www.nhoj.co.uk/applescripts/

when you sync, be sure you use the "overwrite iPhone data with data from this computer" option, or your duplicates will come back to your system.
