Printing loop I have a Zebra Z4m printer and sometimes when printing larger amounts of text data it acts like there is a buffer problem because it starts printing the same data over again loke it gets in a loop. Then we have to kill the print. I does not seem to hapen when we send small a mounts of text to print.

There is a printhead hot error that will come up on the printer if it overheats the printing mech and it will pause. If it totally locks up I'd suspect the main logic.

Check for missing teeth on the main drive belt.

Firstly make sure your using the correct drive ZM400 rather than Z4M. if you are using the applications driver make sure of headers and footers sizes and the print area is set correctly. If your using odd sized lables download some new drivers from the Nice Label website, they are far more adjustable that the standard Zebra drivers.

Did you switch your ribbon as well?

My problem is listed on this site as well. I have found my problem to be the HP Jetdirect. When I have tested the same print job on the same model printer but using either the the Zebra Net Printerserver II (kindly loaned to us by UniqueID for this testing) or one of our units that has a wireless cisco card the job terminates correctly.

Hello,

Have you tried sending print jobs thru the parallel port only? I think it has to deal with your jetdirect box. You can try reseting that as well.

An unorthodox solution is to install an old driver. Another solution is to use with Codesoft the driver from www.seagullscientific.com, and with Zebra Designer, the Zebra Designer driver. If the printer is connected to the serial port, speeds up communication.

I think your problem comes from your spool server. Check if you can select not to reprint on errors. As far as the error issue is concerned, i need to konw the reason of the errors to help

The use of a Print Buffer will help, the problem happens when there is a buffer overflow. Reboot the printer and let the print queue to resume will fix it every time, a print buffer will help with the overflow, try get one with a fair bit of RAM

Try a reset: press the PAUSE and FEED keys while turning the printer, release the keys when feed the label. You can also try downloading the latest firmware.
