My printer TLP 2844 print with wrong label offset, and every printed label green button turn to red.
I try calibrate it, but it print only a row of printer information and green button turn red, after press it, the printer print another row of information and turn green button to red..
I had the same problem. I found out later there was a small piece of label sticking against the sensor, thus blocking the sensor from sensing the end of the label. As soon as I removed the label (open the cover, it is on the top part) it immediately started to work as usual. Hope this helps.

This is an easy printer to fix since there is only one control button. Turn the printer off. Hold the green feed key down while turning the printer on; once the red light begins flashing, let go of the feed button. This will do three things: the printer will calibrate with the installed media, it will print a configuration label and the printer will go into dump mode. Press the feed key again. One more label will come out with with the words "Out of Dump" printed at the top. If the printer still fails to print, remove the ribbon and try the same procedure with direct thermal labels (UPS or FedEx). From there, consult the manual for more troubleshooting tips.
To change from "page mode" (protrait) to "line mode" (landscape) you need to complete the following steps. 1. turn the power off 2. hold the feed button down 3. turn power on, the feed button should blink, release the button. 4. when the feed button blinks green, press and hold until it turns red or amber. release the button. 5. turn the power off. 6. hold down the feed button and turn power on, the button should blink and release. it will now print a calibration page. 4 blanks followerd by 2 text pages, the last saying "Now in DUMP" press feed to exit. on the first print, the 4th line down will say either page mode or line mode.
You are probably using the Gap sensor on the 2844, unfortunately the shape of the butterfly labels means you are sensing the wide gap between the labels in the centre, so it will not print anything in the apparent gap area on both ends of the label.
What your label or system supplier should have done is supplied you with the same labels but with a 3mm wide black mark on the underside of the label backing paper, centred between the labels. You can then change the printer sensor setting in the driver to Black Mark. You will then be able to print anywhere between the black marks.

make sure you have selected the correct media in the printer driver. The tracking mode has 3 options, (1) Web Sensing (Cut Labels), (2) Mark Sensing (Black marks on back of liner) and (3) Continuous . In your case select continuous. It sounds like the printer is in the wrong media mode and is feeding labels looking for a mark or gap and when it doesn't find one it flags a media error.
