My Zebra LP 2844 printer would print out two labels at once (a good one followed by a blank one). I checked allof the settings and everything seems to be correct with 0 margins in between each label. How can I fix this problem? Thanks!
I've seen this be due to dirty sensor or misconfigured media setting. Clean the sensor in the middle of the edge on the inside and outside of the printer, then if still having trouble - Inside the printer it should tell you that if you are having printing trouble:
turn off the printer
Hold down the feed button
turn on the printer and at the third red flash release the feed button
it will then feed some pages print some info and ask you to hit feed again to exit dump
hit feed again and it will say exiting dump
You have just made it reconfigure media, and it may know when to stop feeding now.

Since the LP2844 is a direct thermal printer, the first thing to check is to make sure you have direct thermal labels - regular label stock won't work. Just quickly scrape your thumbnail across the label, the friction will cause a black line if the label is direct thermal.
1 Check that your label size definition is correct, measure your label height in mm and check that your printer driver settings match.
2 Perform a calibration. How?? when printer is on labels loaded and green light, hold feed key and wait for 2 blinks then release feed key. (If you release it after 1 flash you will print a configuration label)
3 If you are using Zebra Designer, download latest version of Zdesigner V2. Install latest printer driver V2.63. This driver & Zdesigner allows you to calibrate the printer directly from within Zdesigner. Go to File/Printer settings/ advanced options and click calibrate at bottom of page. when printer calibrates then tick the box USE PRINTER SETTINGS and printer will now work properly.
It's possible that the printer did not get a good calibration on the size of the label. There's an optic sensor looking for the gaps in the labels. A test would be to turn the printer off and back on again. When it is ready, just press the feed key. If one label advances then the printer had a good read on the label size. The idea is to see if the printer works ok by itself first.
Now print a label - if you get two labels then you have to look at the software / printer driver as the cause. The printer will only do what it's told to do.
Maybe the printer is not getting a good calibration on the label. If the status LED is a steady RED when trying to print, then the printer thinks its out of labels. A manual calibrationi could solve that.
1. Turn the printer off
2. press and hold down the FEED key while turning on the printer.
3. keep pressing the key until the status light flashes once, then let go
4. The printer will auto-calibrate for the size of label and then should be ready to use.
Press FEED once after its done and 1 label should feed.
First thing you need to check power is coming to printer or not.
If power is coming check printer is feeding properly or not when you press feed button it should feed one blank label.
If it does not feed label then calibrate printer from driver or press feed button and switch on printer hold feed button for 2-3 seconds and leave it .It will calibrate and print test page.
It sounds like they may need to set their "Q" values for the labels they are using. If that isn't it, we may need more info - are they using Zebra brand or custom labels?
To start with, I would ask them to try adding these "Q" value commands:
If that doesn't work, then maybe they can provide the other info mentioned above so we can understand the problem better.
If the printer is printing nothing but blanks, try another roll of labels.
If the printer is printing blanks in between labels, it probably needs to be gap sensed. You can do this by: 1. turn the printer off. 2. hold the feed button down and then power the printer back on while still holding the feed button down. 3. release the feed button when the light flashes. 4. the printer will then regap itself 5. when the regapping is done, press the feed button once. It will print on the label that it is 'out of dump' 6. the printer should then be ready to go.
It sounds like it needs to be re gapped. Try this: 1. Make sure that printer power is off. 2. Press and hold the feed button. 3. Turn printer power on. 4. When the status light blinks, release the feed button. 5. The printer advances the media to measure and verify the length of individual labels or tags. The printer then prints a status summary and remains in diagnostic dump mode. 6. To begin normal operation, tap the feed button. The printer prints "out of DUMP" and advances a label.
