Greek code page probe — NETUM NT8330L (or any unknown printer)
|
||
Usage: python print_codepage_probe.py <IP> [PORT]
|
||
Example: python print_codepage_probe.py 192.168.1.50 9100
|
||
|
||
Prints one long receipt that tries every candidate (n, encoding) combination.
|
||
Circle the block where you can read "ΚΑΛΗΜΕΡΑ ΕΛΛΑΔΑ" correctly.
|
||
That block tells you the codepage_n value to use in the printer profile.
