Without knowing exactly how things are setup, it's hard to say what is wrong. From the
Mac OS X ICA Admin Guide:
To print to your default printer
1. From the client File menu, choose Print Automatically for printing to take
place using your default printer and its settings.
2. Within an ICA session, from the application's File menu, choose Print.
3. In the Print dialog box, select the printer driver most suitable for the print job.
4. Click Print.
To print to any connected printer
1. From the client File menu, choose Print With Dialog in order to select a printer
other than the default. (If the menu bar is not visible in the session window, see
“Showing and Hiding the Menu Bar and Dock” on page 44.)
2. Within an ICA session, from the application's File menu, choose Print.
3. In the Print dialog box, select the printer driver most suitable for the print job.
4. Click OK.
This opens the Macintosh Print dialog box. (In some circumstances you may
see the Macintosh Page Setup dialog box before the Print dialog box opens. If
this happens, check the set up settings, change if necessary, and then click OK
to continue to the Print dialog box.)
5. Select the printer you want to use and click Print.
and
You can also turn printing off for a specific connection file.
To turn printing off for a specific connection file
1. Before you make the connection, open the connection file you want to edit in
the ICA Client Editor.
2. From the Connection Properties tab, select Turn Printer Mapping Off for
this Server.
3. Click Save.
Note In some circumstances, when you connect to the server, the Macintosh
Printer icon is still present even though you turned printer mapping off.
However, if you try to print, you see a Windows error message saying there is a
problem when trying to print and printing is not possible.
So, maybe printer mapping somehow got turned off on your client, or the server is not allowing it.
