Star Micronics TSP100u

[Roger Foreman]

I am using a MacBook version 10.6.8.

The receipt printer font set is printing too small for most people to read comfortably.  Changing the paper size does not correct the issue; altering the page size cuts text off on the right margin. Either the internal margin settings must be adjusted to allow the text size to increase automatically or the font size must be changed in the config file.  I require help with correcting this situation because not familiar with changing the config file for this printer.
I appreciate any help or suggestions.
Thanks.
