Our restaurant is on RES version 5.5. All of our TM-T88V printers are on IDN interface, and these all print guest checks and credit card receipts at the standard 6 lines per inch. However, we have one TM-T88V on an wireless IP interface. This printer prints the same checks and receipts at 8 lines per inch, resulting in the receipt lines being squished together. The characters per line are the same. The DIP switches and Epson internal settings are same. I have not been able to find any sort of driver in the Micros/Res directories. I am wondering if there is an ISL script or something sending an Epson ESC 0 (8 lines per inch) versus standard of ESC 2 for 6 lines per inch. Thank you in advance, any help and clues are appreciated.
