I absolutely love this thing! Instead of waiting for my poor printer to finish up printing, then cutting out labels, taping them on and ensuring that the tape is actually holding on I can slap on a thermal label on move on. In just two days this thing has already saved me roughly two hours of time. I didn't use the included USB and instead downloaded the drivers straight from the website and had this up and running in about 5 minutes. I absolutely recommend it!Overall, I am very pleased with it. I do prefer my name-brand printer because the print quality is quite a bit crisper (a difference in the dpi) but this is legible, packages are scanned and arrive just fine, so I'm happy to have something that I can travel with. It's durable, easily portable, was easy to install, and is super easy to use. Satisfied customer.I use Stamps.com to print shipping labels, basic account. Prior using 8x11 2 labels per sheet with HP Instant Ink max cost could be 17¢ per label if I was over my Instant Ink print quota. With the Comer = 2.7¢ 4x6 label. Comer in my experience is printing 60 labels per minute. I'm using 4x6 Comer rolls, 350 labels per roll. Comer notes to set the printer format to 100mmx150mm or 4x6 label. I tried that on Stamps.com and it would not print correctly. Mess. Than I found the printer setting at the top of address fields and chose 4x6 Roller. Worked Perfect. Very Fast. Couple of annoyances: 1. Printer Driver Win10 is set to call the Comer "RE418" a part number? I went into devices / printer properties and changed it to "Comer Label Printer", worked fine no issue renaming it. It does not come with any dedicated label software, however any Office365 app can be set to replicate 4x6 labels, including Excel. Likely their is some freeware label software out in the Inter-webs if needed. I did go into Comer printer properties and changed the density from default setting of 8, to 12. Max is 16. At 12 it printed darker and clearer with no printing speed loss. With Amazon clip coupon I paid $99. Half the price of other "XL" label printers. This is a no brainer of a bargain and its a speedy work horse, that works flawlessly. Just in case I did order a 10FT USB A cable to from Amazon $8, the one that came with it measured 5FT, and I needed 8. Unless you need some dedicated label printing software and you don't have Office or freeware label software, then you might consider another option. Highly recommended from an initial skeptical perspective, this is winner.This printer is of great quality. You can use roll labels or flat labels. Super easy to install and set up. Good printing quality. Nothing to envy to Zebra printers.So— as per my first review— thermal labels do not come with this printer. But, once a roll is inserted the printing works well. It prints quickly and cleanly. If I have any quality criticism it would be that the contrast is slightly low. Nevertheless, this was a sound investment.The process of paying for and printing a label is pretty much seamless through eBay. Through UPS and USPS it's a bit cumbersome. Several more steps are required through these services, which is not unexpected, but tedious. And, while eBay and UPS are working just fine, USPS is somehow preventing me from printing labels— for over a week, now! (Even after four customer service calls, and six representatives, including three tech troubleshooting experts, there is no resolution.) Of course, that's not the fault of the printer, but it's evidently a glitch in the USPS system which can shut you down real fast. That is something useful to know.Also, the software, while functional, is not quite as easy to set up as what you may have become used to these days, but it isn't difficult. Ultimately, it works.All in all, I am happy with this thermal printer, and would buy again.We are using this printer as a replacement for a Zebra 2844 printer which after many many years of great service, an employee broke it. This printer works just as well - only time will tell. We use with a custom app, printer driver a bit difficult to obtain but once we got it, installed and works fine!Works as advertised. Though, the shipping sticker roll will steadly goe out or alignment and needs re adjustment after 50 or more prints, so if don't print out more than 40 stickers in a row, you'll dig this machine.This was an okay value and worked fine for the last 10 months. I only use to print labels for a very small business. The print quality is touch and go. Often prints partial labels. Now, less than a year later - it just turned off and won't power back on. Disappointing!
