Hi
have a 3com wireless print server set up on my network, all works fine can
print pages that are not too graphic intensive, however when i go to print a
picture it halts and when I look at the printer status a print job shows up
but with always a 8.93Mb size. I presume this is a buffer overun problem but
my question is:
is there anyway to overcome a buffer overrun problem and if not would any
other wireless print servers cope better.

Thanks
Olly

Well, the real question is where is the buffer overrun occurring? It
could be in the client that's sending the print job, in the TCP flow
control mechanism between the client and the print server, or in the
interface between the print server and the printer. Since all you've
disclose is the manufacturer of the print server, I can't begin to
speculate which one of these is causing the problem. Probably the
printer but that's just a wild guess.

Well being a relative novice in wireless networking I wasnt really sure what
kind of information would be useful, The printer prints fine when connected
via a usb cable but just doesnt print when trying to send it large files
wirelessly.
I think i may be using SMB printer protocol (Maybe not correct terminology)
would peer to peer work best? and if so how do i set this up using win XP

I'm glad you asked. I need a good rant. In order to get any question
answered without guessworks, we need:
1. What problem are you trying to solve? One sentence is fine.
2. What do you have to work with? That means maker, model, hardware
version, firmware version, operating system, release, etc. In other
words, the numbers.
3. What have you done so far and what happened? Error messages are
useful.

There are some other things that are useful, but these are the
important items. You delivered #1 and about half of #3 just fine.
However, the equipment and software list is almost totally lacking.
All I know is it's made by 3com and that you have some USB printer.
Not enough info to make even a bad guess.

- Model number of the print server.
- Model number of the printer.
- Model number of the wireless router or access point.
- How is the router or access point setup?
- Type of printer interface (serial, parallel, USB, whatever).
- Client computer? Operating system? Version?
- Program used to do the printing? How are you testing this?
- Is it just one program or do all of them overflow?

Pass.
