After some tries and google searches I found a way to use the wireless printer server from LevelOne in Ubuntu. The following problems are known concerning this server especially in Ubuntu 8.04:

• The printer stops printing after a half or one page.
• Printer jobs do remain in the printer queue after the printing is completed and the job is printed again after the next boot of the computer.
• Some people have trouble installing the corresponding network printer.

To install the server you must pay attention that you choose a "LPD network printer" to be installed, and no IPP printer or other kinds of network printers. Even if the printer works perfect with IPP on Windows you will run into trouble with that protocol on Ubuntu. Then enter the IP address of your printer server as the host address and "lpt1" as the queue. If you use the actual version 8.04 of Ubuntu, there is a bug concerning LPD network printers and without a little workaround you won't even be able to print a testpage:

1. Backup your /etc/sysctl.conf file
   sudo cp /etc/sysctl.conf /etc/sysctl.conf.backup
2. Edit the file /etc/sysctl.conf with you favourite editor, for example with kate
   sudo kate /etc/sysctl.conf
3. Add the following line to the end of the file and save the file
   net.ipv4.tcp_frto = 0
4. Execute this command to make the changes productive
   sudo sysctl -p

Now your should be able to print to your printer using the printer server without problems.
