Question edited for clarity.
First try a simple Power Reset. Turn it off for 5 minutes and then back on.
The Manual has procedures for Self Testing and Diagnostics, plus a Full Software Reset.

Good Day
I trust that you are well, which interface are you using (Serial, Parallel or USB) on printer to connect to the computer you printing from?
Have you tried printing a test page from the print driver?
look at either end of the printer head rails and you should find a lever with +plus and - minus move lever to + plus till you are happy with the quality
For the issue with your ribbons take the spool and wrap a section of it about half way around the pulling portion and use some duct tape to place it on it securely. then take the same portion and rotate it a few times as to wrap the ribbon around it at least three to four times making sure it is snug all the while. that should remedy the spooling tension issue. Sorry I can't help with the printing issue. try updating the driver and if that doesn't work try replacing the printing head as it may be defective now. The Z4000 are old school, ours just broke down as well and we called tech support, the guy laughed when he heard we had one in use and thought I was joking... :(
The Zebra ZP 550 will work with the GK 420t driver which is free for download at zebra.com. After installing it restart shiprush and your zebra printer will show up in your printer selection menu.
If your Zebra LP 2844 printer is experiencing shifting or off-center printing, there are a few possible causes and troubleshooting steps you can try:
Check print settings: Ensure that the print settings on your computer or label design software are correctly configured for the label size and layout you are using. Make sure the label dimensions and print margins are set accurately.
Calibrate the printer: Perform a calibration on the printer to ensure it is properly aligned. To calibrate the Zebra LP 2844, follow these steps:
a. Turn off the printer. b. Hold down the feed button. c. While holding the feed button, turn on the printer. d. Release the feed button once the green status light begins to flash. e. The printer will feed labels and automatically adjust the label alignment. f. Once the printer stops feeding labels, the calibration is complete.
Adjust label position sensors: The LP 2844 has label position sensors that detect the start of each label. If these sensors are misaligned or dirty, it can cause shifting or off-center printing. Clean the sensors using a lint-free cloth and ensure they are properly aligned.
Check label alignment: Ensure that the labels are loaded correctly and aligned properly in the printer. Make sure they are inserted straight and centered in the label guides.
Inspect the print head: Check the print head for any debris, adhesive residue, or damage. Clean the print head with isopropyl alcohol and a cotton swab if necessary. A dirty or damaged print head can affect print quality and alignment.
Update or reinstall printer drivers: Ensure that you have the latest printer drivers installed on your computer. If the drivers are outdated or corrupted, it can cause printing issues. Visit the Zebra website and download the appropriate drivers for your LP 2844 model.
Test with different labels or ribbons: If the problem persists, try using different labels or ribbons. Sometimes, the issue could be related to the specific media being used.
One possible reason for this issue could be a problem with the printer's ribbon sensor. The ribbon sensor is responsible for detecting the presence of a ribbon and ensuring that it is properly aligned. If the sensor is not functioning correctly, it may cause the printer to throw a mechanical error and check the ribbon whenever the card reservoir lid is opened.
Another possible cause of this issue could be a problem with the printer's motor or drive system. If there is an issue with these components, it may cause the printer to stall or throw an error message when attempting to print.
To resolve this issue, it may be necessary to perform some troubleshooting steps. First, try cleaning the printer's sensors and rollers to ensure that they are free from debris or dust. Additionally, check to make sure that the ribbon is properly loaded and aligned in the printer.
If these steps do not resolve the issue, it may be necessary to contact Zebra technical support for further assistance.
