Thank you for contacting ScanPower support.  Please use the instructions below.  Please ensure that you un-install any and all DYMO drivers associated with your printer to ensure that no duplicate drivers remain.

Firefox and Chrome have released recent updates which may have thrown off your ScanPower printing settings.  Please un-install all versions of the printer driver for your DYMO on your computer.  Next, restart your computer.  Then, re-install the driver using the appropriate link provided below.  Next, restart your computer.  Restart your browser, log back into ScanPower and go to SETTINGS > LIST.  You should see the printer detected at this point.

NOTE: Firefox no longer requires a plug-in, unless you are using an older operating system.  

DYMO Direct Printing, in conjunction with the Firefox or Chrome browser, is the recommended printer set-up for ScanPower.  This printer set-up is specific to ScanPower and different from the basic DYMO set-up.  Below is a video tutorial which will walk you through the set-up process.  If the printer is still not detected after going through this process please see the additional troubleshooting suggestions below.

Recommended Equipment:

DYMO 450 LabelWriter Printer

30252, 30334, 30336 or 30321 Labels

Recommended Software:

Please make sure you have the latest driver for your Dymo (or other) printer.  Please use the links below rather than the set-up disc which came with your printer.  Some times updates are released after the production of printers and the disc is no longer up to date.  Also, please ensure that you do not have more than one printer driver for your printer installed as this will result in ScanPower not detecting your printer.

UPDATE 03/18/16:  DYMO Direct Printing is now available with Firefox and Chrome.

 DYMO Software Mac, version 8.7.2 (updated 6/7/2018)
DMYO Software Windows, version 8.7.2 (updated 6/7/2018)

DYMO Direct Printer Set-up Video Tutorial:


If printing is still not working in either Firefox or Chrome following these instructions (and after trying both browser options - Firefox and Chrome), please enter the following link into your browser: https://localhost:41951/DYMO/DLS/Printing/Check

If you get a message that the DLS Web Service is up and running, then reload ScanPower and see if the printer is recognized in Settings->List.

If you get a message ERR_SSL_VERSION_INTERFERENCE you may need to turn off TLS. Follow the instructions here: on the 

DYMO Developer SDK Support Blog

If you get a message that the connection is refused this likely means the DYMO web service is not running. In Windows click the Windows Icon then select Run and enter the path below:

C:\Program Files (x86)\DYMO\DYMO Label Software\DYMO.DLS.Printing.Host.exe

Alternatively, you can search for "Command" and load the Command program and paste the above into the prompt.

This should allow the link above to localhost to successfully connect and you will see the Dymo service icon in your system tray.

If at anytime during this process you get a notice of "an insecure connection" please trust that the connection is fine, click ADVANCED and then PROCEED or ADD EXCEPTION to continue on in the process.

If you get an error dialog saying: "Your process does not have access rights to this namespace..", you'll need to allow Windows Communication Foundation (WCF) access to the localhost via HTTP.   Click on the Windows icon in the lower left (formerly Start) and type Command in the search bar. Right-click the Command results above and select "Run as Administrator". Next paste the following command into the prompt and press enter: netsh http add iplisten ipaddress=

If it is still not working, just shoot us a note and we will screen share with you to debug ... 

*DYMO Direct Printing is the recommended print method for ScanPower. If you wish to manually configure your printers the instructions to that can be found in the Alternate Printer Setup guide.
