How to configurate multiples printers with findtrays

tinin

Hi all & thanks in advance for yours topics.

I have a problem with the configuration of the findtrays.exe and the "Paper tray" table (into nav).

Three printers has been configurated in the same nav server.
Two of them the same printer model (same printer provider). (Manual tray and three more trays. To use all)
One of them the most updated printer model. (Manual tray and three more trays. To use all)

Using the findtrays.exe I have two printers with the same configuration:
Manual: 264
T1:258
T2:259
T3:260
And the other one with:
Manual: 258
T1:260
T2:261
T3:262

Is not possible to use same ports for different printers into the nav table ("Paper Tray").
And I don´t know if is possible to change the automaticaly numbers shown with the findtrays in the server.

Somebody can help me? (I cannot use code into nav)
