I have used several Dymo printers in the past 10 years and generally they work well. This model does have a few issues. When printing more than one postage label it will misprint or skip a label or not print a stamp about every 10th time. As a result, I am wasting several stamp costs each month. This occurs more if printing more than 4 stamp labels, so I keep it to 3 or fewer each time I print. Even then, it might skip or misprint. The monopoly Dymo has on the postage labels is annoying. They claim to not support any other labels, yet price these labels significantly higher in cost than other labels where they have competition. 

I have contacted Dymo twice with no response about a replacement adapter. We pretty much have a dymo on every desk at my job and I can't even get one adapter. It's not even an option to just purchase one on the website. It shouldn't be this difficult!

I've had this printer for about 2 years. I have had no problems with it whatsoever. Works like a champ. I just wish Dymo had a twin port wireless printer. Sometimes I need to print something from my phone. No way to do that with this thermal printer.

The 450 Twin Turbo has been great for me with the old software but the new software, Dymo Connect, is not meant for the 450 twin turbo. I need the option of which label to print which is why I bought this particular printer, but the new software does not allow this option or at least I can not find that it does. The new software is not user friendly or twin turbo friendly. Recommend product but not software. I want the old software back.

I am on my third DYMO labelWriter 450. For some reason, the left printer wraps the label around the roller and when you remove it, it damages the roller and the DYMO will not work. I have paid for three label makers over the last three years and am not ready to invest in a 4th! Of course I have had to toss the first two and now this one is headed for recycling bin. So very disappointed as it is wonderful when it works for only a year.

My Dymo desktop software (Mac OS Sonoma) stopped working, forcing an "upgrade" to their Dymo Connect app. The new software cannot see my USB-connected printer. It's safe to say this is a complete piece of crap. If I have to buy a new label printer, it will never again be a Dymo.

This is ridiculous that it does not come with a CD and a user manual. So far, the website sucks. I download three users guides all for Belgium. I have spent 30 minutes on the website and still waiting for DC setup.exe to download. In the meantime, looking for an English user guide to set up the labels correctly. I am ready to return this and forget about it.

I have used the DYMO LabelWriter 450 Twin Turbo Direct Thermal Label Printer for several years. I own three: one for home office use and one at each of two non-profit organizations where I volunteer as the treasurer. I can print a variety of labels, including stamps (although I prefer Stamps.com). Since this is a twin unit, I usually have delivery address labels in one side and stamps in the other. I only swap the labels when I need to print something unique (for me), such as file folder labels. Like many other customers, I prefer the older DYMO software, but that's easily remedied by downloading DYMO Label v.8.

Ever since we have connected a new LabelWiter 450 Twin Turbo onto a new HP Desktop, we are met with frequent hangs of the computer boot process. Disconnect the Dymo-printer, which is connected through USB, and the computer boots like a charm. We have tried everything: changing the boot order, so USB-boot has a lower priority, disabeling USB-boot completely - nothing helps - the Dymo needs to be disconnected to get the computer to boot. I have never seen this before .....

I cannot download driver for windows 10. Been on here almost 1 hour downloading one driver after the other and can not get it to work. What is wrong with this everyone is complaining about the same thing. I have it on another computer and it works but not both of the printers only one does. Need this fixed asap.
