[Samba] XP to Samba printer access delay

[Andriy Rysin]

Hi all,

I've got a question, may be somebody can help me:
1. I've got a printer (Epson Stylus Photo R220)
2. Attached to Linux box via usb (Mandriva 2006+)
3. Configured with cups (cups-1.2.0-0.4892.1mdk)
4. Shared with samba (samba-server-3.0.21a-1mdk), user - tried guest and
real linux user
5.On WinXP native driver install from CD (later updated from Espon site)
6.From WinXP I can see the printer and can print ok, except one thing:
7.Every time when I open properties of the printer, print preview, every
page of the print wizard etc... I have a big delay (1st could up to
1min), during which WiFi card is blinking hard but network throughput is
far from reaching the limit of 802.11g

I tried to turn on debuggin on samba but even at level 3 it gives about
1.5-2 Mb of logs for each such delay, though that log info did not help
me to find the source of the problem.

Part of the log (the rest of the megabytes are almost the same pattern)
and config is listed below.

I also tried to turn off "bidirectional" option in the printer
properties on XP but that did not help.

Thanks in advance,
Andriy
