That's a batch error, more than likely due to a communication issue between the pc and the printer. If you reboot the printer, THEN reboot the pc you should clear that error.
This error sometimes occurs when the printer has been shut down whil logged into your software, which disables communications between pc and printer. The error indicates that the printer didn't receive enough data to properly print the batch of labels/tags.

HP Printer Error 49 is normally caused by a communications failure between your PC and the printer. If you have an HP printer you may receive the HP Printer Error 49. This is normally effected by a communications breakdown between the printer and the PC, or related file errors.

Are you sure it is a 'command error' and not a 'communication error'. I could not find anything on a 'command error' but did find this on a 'communication error'.


Q: Why am I getting a communication error when I try to print?

A: Check the following if you are getting a communication error when printing:

Make sure the type of driver you installed matches the ink type in the printer. Verify the ink type by checking the part number on the ink cartridges.

Make sure the printer interface setting matches the connection type you're using. By default, the printer interface should be set to Auto, which supports all connection types.

Check the physical cable connection and make sure the cable is not be longer than 10 ft. You may want to replace the cable.

You may also get communication errors if the printer name is not set correctly. Contact EPSON at (888) 377-6611 or (562) 276-1305 to get instructions on how to verify this.


You might want to check to see if you have the current drivers for your printer and operating system; a new driver can be downloaded here.

Trust this is helpful.
