Sorry for late response - we had holiday.
So as an update (perhaps someone knows what happens):
No message anymore (?!) but the printer prints out a little garbage and 
nothing more.

I can see several SPOOLSS_WRITEPRINTER calls to transmit the job.
The samba log looks like this:

[snip the logfile]
api_rpcTNP: api_spoolss_rpc op 0x13 - api_rpcTNP: rpc command: 
000000 spoolss_io_q_writeprinter 
    000000 smb_io_pol_hnd printer handle
        0000 data1: 00000000
        0004 data2: 0000000a
        0008 data3: 0000
        000a data4: 0000
        000c data5: af cb df 3c 2d 07 00 00 
    0014 buffer_size: 00001000
    0018 buffer: .............%-12345X at PJL JOB NAME="Test Page".. at PJL SET 
[logfile continues...]

The problem is, that the first 12 bytes of the buffer do not belong to the 
They are: 0e00 0000 xxxx 0000 d1ad 0000
The x differ, rest allways the same.

When using a Win2k machine as spooler, the whole communication looks 
different, but the job does not contain these sequences. 
So I wonder, what lets the driver write these bytes and what do they mean?

Any ideas?
