4"x6" Thermal Shipping Label Printer ITPP941 with Lables

Print Quality issue

1. Q: why My labels are not sharp / dark
A: The most common reason for low-quality prints has to do with low-quality source file

If it seems like your original low-quality print was designed for 8.5 x 11 size, please to see if you can change the label settings to be 4 x 6.

Our recommendation is to use a commercial solution which will automatically download your orders from your online channels (eBay, Amazon, Etsy, etc.) and provide you with a simple button to print your 4 x 6 labels in high-quality.

If only parts of your label look faded, the reason could be one of the following:

1) Label
The darkness of the label depends on the label manufacturer. High quality labels produce darker prints.

2) Margins and page size
Please ensure the content is taking up the whole label. If there are extra borders, your design may be "shrunk" printed in smaller size resulting in faded content.

3) Print density and speed

Within your ITPP941 printer preferences, you can set your "Density" and "Speed"

By default, ITPP941 is set to print at its fastest. Slowing this speed will result in a higher resolution.

Note: Increasing the number for your density / darkness will result in a darker print. Setting the density too high will result in unwanted dark lines and/or label getting too hot and sticking mid-way to the printer head. Decreasing this number result in a lighter print.

For Windows:

You may access these settings by going to your Control Panel -> Printers and Devices -> Right Click on ‘Label Printer’ -> Printer Preferences -> Page Setup -> Setting

For Mac:

Look for drop down menu under "Printer Features".

2. Q: Why there are white spots in my print

A: It is likely that the printer head has gotten dirty.

(1)Please turn ITPP941 off and allow it to cool down

(2)Please use the provided alcohol pads to wipe the printer head clean. Any 70% Isopropyl Alcohol pad would work. These are commonly available in pharmacies and grocery stores as well as on Amazon. Image below shows the highlighted areas that could cause this fade / dead zone.

(3)Allow 2-3 minutes for components to dry, then turn ITPP941 back on.

Finally, it is possible that something has interfered with ITPP941's driver. Please uninstall ITPP941, restart your computer, and install the driver: http://bit.ly/ITPP941-drivers

Label issue

1. Q: Why i am printing blank labels?

A: (1) The most common reason is that your labels are loaded in upside down. Please ensure your labels are properly loaded. The label that you peel off should be facing the ceiling when it comes out of the printer
(2) Ensure your labels are "Direct Thermal" labels.


2. Q: Why the printer is skipping labels or continuously feeding?
A: There are two main causes for ITPP941 skipping labels or continuously feeding. This behavior is usually after you change your label type, size, or manufacturer.

(1)ITPP941 hasn't learned your label [Most Common Reason]

①Please re-run the automatic label identification so ITPP941 can learn your label.

②To make sure your computer is not sending print commands to ITPP941, please disconnect the USB cable from your ITPP941 printer, then simply press and hold the top circular button on ITPP941 until you hear one beep. Then let go.

③ITPP941 will then move the label back and forth to learn the gap size and other properties of your label. You should now see a green light and label placed at the tear off point.

④Please re-connect the USB cable to ITPP941 and try your print.

(2)Your operating system is sending a longer / shorter label to ITPP941.
Please ensure you have the correct label size:

①For Windows
Please go to Control Panel -> Devices and Printers -> Right Click on ITPP941 -> Printer Preferences -> Advanced Button.
Most 4 x 6 labels are 100mm x 150mm

②For Mac
Please select 100mm x 150mm or 4" x 6" size during on the print prompt window

Note: The application you are using (i.e. Adobe Reader) could be over-riding your driver label setting and sending the print in a larger / smaller size to ITPP941. Look for "Page Setup" or "Paper Size" in the print prompt and ensure it is set to the size you want.



3. Q: Why my label is printing sideways?
A: The most likely reason is that your label is not properly formatted for 4 x 6 label printing. ITPP941 prints exactly what you see on your screen in the same orientation. So if the label looks side-ways on your screen or if it has a lot of white space around the label, ITPP941 will print it side-ways and with the same amount of white space.

If your label is 4 x 6 but just provided sideways, you can setup ITPP941 to rotate it for you automatically:

(1)On Mac

During the print prompt, select your label size under Presets, then navigate to Printer Features -> Page Options and Select 90 under "Rotate."

(2)On Windows

Go to Control Panel -> Devices and Printers -> Right click on ‘Label Printer’ -> Printer preferences -> Go to Page Setup -> Under Orientation choose Landscape and Click Apply / Ok.

4. Q: Why the label is getting stuck / prints only half and stops?

A: ITPP941 prints by heating your label in very specific areas.

If your label is getting stuck (usually during printing something really dark like barcode or a thick straight line), this is most likely due to your print density being set too high for your label.

This causes the label to get too hot and get stuck to the print head. Various labels respond to the same level of heat differently.

Please set your print speed to "4" and density to "2" and try your print again. If your label is too light now, please increase the density by 1.

(1)On PC:

Go to Control Panel > Devices and Printers > Right click on ITPP941 > Printer Preferences > Page Setup

Adjust Speed / Density and click on OK. 

(2)On Mac:

Access these settings directly from the print menu as shown below.

5. Q: Why the same label keeps printing?

A: When ITPP941 doesn't believe a label was printed correctly, it will attempt to re-print it.

If this keeps repeating, this is most likely because ITPP941 hasn't learned your label's properties. This is usually followed by a blinking red light.

1) Please turn ITPP941 off using the black switch behind the printer and turn it back on. This clears any pending print jobs.

2) Please ensure you have several labels available behind ITPP941 and one label loaded for ITPP941 to print.

3) Please press and hold the top button until you hear one beep, then let go. This starts the automatic label identification and you should see your label moving back and forth and stopping at the correct tear off point.

4) When you a see a green light, please try your print and it should print perfectly moving forward.



Other Issue

1. Q: Why my printer doesn't turn on?
A: Some of these suggestions may seem mundane, but often they do fix the issue.

(1)Please ensure the wall plug has electricity by plugging another device into that same plug.

(2)Please follow the power cable to the adapter and check that the cable that goes to ITPP941 is plugged in all the way into the power adapter.

(3)Please ensure the plug that goes into ITPP941 is fully inserted.

(4)Please turn the power switch off and on. This switch is located on the back side of ITPP941.

2. Q: Why the red Light is Flashing?
A: Red light is an indication that ITPP941 has a problem with your label.

Most likely, ITPP941 needs to re-learn your label.

Please ensure there are multiple labels available to ITPP941 and then run the automatic label identification. Simply press and hold the top button on ITPP941 until you hear one beep. ITPP941 will then move labels back and forth to learn the gap and other properties of your labels.

If automatic label identification does not work or red light remain, please turn off ITPP941 by using the power switch on the back and turn the unit back on.

3. Q: Why nothing happens with I try to print?(The green light is on)?
A: The most likely reason is that ITPP941 is connected to a new USB Port. Windows will register ITPP941 as a "new" printer whenever the USB port changes. Thus when you print to the "old" printer, it simply keeps it in the print queue.

This behavior exists so that you can run multiple ITPP941 printers from the same computer, each with different label types and settings.

How to fix:

(1)Please open your Control Panel -> Printers and Devices and note which ITPP941 Printer is "active". It may be ITPP941 Printer, ITPP941 Printer (Copy 1), ITPP941 Printer (Copy 2), etc. Then be sure to print to the same active printer name when printing.

(2)Alternatively, please unplug and re-plug ITPP941 into the same USB port as before and that should restore your printing without further changes.

4. Q: Why ITPP941 keeps beeping?
A: If ITPP941 keeps beeping, it most likely due to its power source. Please ensure you are using ITPP941's power adapter and that all connections are secure.

Please try plugging it directly into the wall outlet.

5. Q: Why ITPP941 is making loud noise when printing?
A: This is most likely due to your print speed being set too low or density set too high. Please set your print speed to "5" and density to "4" and print.

(1)On PC:

Go to Control Panel > Devices and Printers > Right click on ITPP941 > Printer Preferences > Page Setup

Adjust Speed / Density and click on OK.

(2)On Mac:

Access these settings directly from the print menu as shown below.

6. Q: Why the printers print extra blank labels after the prints?

A: 1. Please check if the page size set in the driver matched the size of the labels that using in the printer.

①Windows: Go to the ‘printer preferences’ ---> ‘advanced’ ---> ‘paper size’, select the correct size for the printer(If you are using 4x6 paper, please select the 100*150mm)

②MacOS: If you print a 4x6 size page. In the print dialogue, please be sure to select your "Paper Size" appropriately (for example 4 x 6).
