Zebra LP2844-Z - no longer prints a barcode on a specimen label

Epson standard code is totally different. EPL is Eltron printer language. I've not programmed in it, but there should be a programmers manual out there somewhere.

Define your label size correctly. Measure your LABEL exactly, do not include the backing paper or the gap. Calibrate the printer. HOW?
Power off printer. Press and hold the green feed button down and power printer on. Count one, two and release green button. The printer will calibrate and move labels and then print some stuff on the label. Wait until it has comletely stopped. wait another few seconds and the press the feed key once. The printer will print "out of dump". You should now be ready to print again.

Same here... Can't be the printer - has to be something with either the paypal software or the driver since my 'SAMPLE' prints solid as well. Did you ever find a solution?

Update the printer firmware, download latest printer driver from zebra website.

Please be aware that zebra Lp2844Z is different with LP2844.
LP2844 - Eltron

LP2844Z - zebra

please make sure the programming language is correct

Try to use this driver in www.seagullscientific.com, it is better that zebra driver.

This sounds like the Density setting is set to light. The selection is 1-15 I think. In the windows driver look at the advanced settings and you should find Density is one variable. set it to about 11 and see what happens.

OS X 10.5.2 and above have built-in ZPL and EPL drivers. Plug the printer in to USB, go to System Preferences > Print & Fax, click + , and choose the Zebra driver. For the LP2844 you choose the EPL2 driver.

We've been having problems with ours. Make sure that the properties are correctly set, landscape, portrait, 180' rotation, label size, on the printer properties. Then check again through whatever package you are using 'printer properties' and try a print. You may have to re-enter properties each time you print.
