Make sure to select the proper printer when you send it to print. Also, make sure the printer is calibrated to the size labels you are using.

SOURCE: Zebra LP2824 not printing

Sounds like you put your printer into line mode. Line mode prints code so you can see what is sent to the printer to look for possible mistakes in the code.

To switch from line mode back to page mode.

  1. Turn printer off.
  2. Press and hold the feed button down. And switch printer on.
  3. Release the feed button when the LED flashes red.
  4. When the LED flashes green, press down the feed button.
  5. When the LED flashes amber release the feed button.
  6. Try printing now that the printer is back in page mode which is used for print your labels; line mode prints the labels code.
  7. Do this fast or else it wont work if you are slow.

SOURCE: Hi,

The TLP2844 can print from any windows application providing the application can use a windows printer driver.
The page size oof the .pdf needs to be the same size as the physical label size.
