Basic printing can be accomplished by using the /c switch.
telnetc /c PRINTER
In order to print to multiple printers at the client, or to set up a default printer without the /c switch, you must modify the telnetc.ini file, located in the Companion installation directory. Using the telnetc.ini file, a user can have up to 20 client-side printers available during a telnet session.
A server side port can be assigned to a specific client side printer, removing the need to toggle between printers. For example, to have any job printed to port lpt1: on the server print to the printer ClientPrinter on the client side, add the line:
ClientPrinter=lpt1
And any job printed to lpt2: on the server print to DifferentClientPrinter on the client side place the line:
DifferentClientPrinter=lpt2
under the [Printers] heading.
The syntax is the client side printer name=the server side port being monitored.
