I am working on a VB based Hotspot Ticket system.
It uses a POS printer to produce tickets similar to what you would see from a retail store recept.
It will take the CSV files from RouterOS, deteman the proper printer (reachable via TCPIP) and print the ticket
with appopriate verbage, UPC code for inventory and serial numbers if needed. (Serialised by ticket and cross referanced to the user ID.)
Custom Graphics can be added as desired.
The tickets are barcoded as well…
There is a sample available on the MikroTik WIKI…
Kick me a note if interested.
