Printing without text in Terminal Server Windows 2008

oneoftherrrr

Some Terminal Server users print documents with only the lines of the boxes, without any text. This is also true for the print preview. Other Terminal Server users are OK.

This occured after an Olivetti d-Copia KX 300 printer was installed (2 printers, for 2 trays) on the terminal server. A first try to resolve the problem was removing both printers, and re-installing them. This was done several times. Several drivers have been tried.

Now all occurences of these Olivetti's, their drivers and registry entries have been removed.

Navision (sql, 4.0 SP1, client 5.0 SP1) was resynchronized for all users, although no rights were changed. Windows security was not altered neither.

As the Navision printing and pre-view use a printer driver, several default printers have been selected: no avail.

Deleting the ZUP file: no success.

It seems that certain TS session are infected, and some not. Once infected, it remains so, also after log of. Closing and opening of Navision has no influence.

A user that was absent a few days has not been infected. Perhaps the infection occured only on the TS user sessions that were open at infection time, but this is only a guess.

Removing a TS session, via System Properties - Advanced - User Profiles, and recreating it via a new logon has no influence.

Creating a new Windows user, and making him a super Windows logon user: no success.

All users have Windows logon.

The only workaround I have found for the infected users is using database logons. On an infected TS session neither the windows logon nor the database logon works. On a non infected TS session both types of logon are OK. So this really points to a TS problem.

Can anybody help in solving this enigma?
