Zebra GK420T Thermal Transfer Printer
The Zebra GK420T is compatible with Visual Jewelry Shopkeeper and quite a few users have this.
The Zebra GK430T seems to be almost the same but with higher resolution so it may be able to produce smoother text at smaller sizes. E.g. :
The GK420T supports printing at 200 dpi (dots per inch) - equivalent to 8 dpmm (dots per millimeter.)
The GK430T supports printing at 300 dpi (dots per inch) - equivalent to 12 dpmm (dots per millimeter.)
If you use a GK430T, then be sure to change the the dpmm resolution setting in the layouts, and you may also need to try larger fonts.
