I have a toshiba laptop model with windows 8.1. I'm trying to download a driver for a citizen clp-621 label printer. for some reason it will not work. I think the label printer is 5 to 6 years old SNjmaa001323. any suggestions?

Hi there... i used to have the same problem... and i found and old driver designed for both PN50 (mine) and PN60... but i did´nt work... i could get it working using the Epson LQ-800 or LQ-2550 emulation printer... this is in your MS Windows System, in the "ADD Printer" feature. Hope it could help you!!...

I have used this type of printer before. Long ago when it was called the C-ITOH. However, never had to change the print head before. I would imagine that if you did - all the adjustments would need changing. Bad Gap would skip labels and bad pressure would make them too light or too dark. If there are any vertical lines (even faint) the print head is damaged. Also, these things are very specific as to media vs ink roller. You cannot use a paper ink roller with mylar labels. Vise versa works but those rolls are more expensive. I am sure you have tested this already but you point pretty exclusively to the "new" print head with your testing. Sounds like you have answered your own question. I would do some continuity tests on the head to see if it carries any current at all. Good Luck!
