I've had the same issues on every Windows network I've worked with. Windows printing is just plain flaky sometimes. Squid has nothing to do with printing, so this definitely isn't a Squid issue. Is is possibly an issue with your Linux gateway, but only if one of the following is true: 1) The gateway is also a network print server 2) Clients go through the gateway to get to the print server If either of those is true, I would suggest asking on a mailing list for your Linux distribution. > What is the printing network port? Depends on how you are printing. Check your client configuration. Windows File/Print Sharing usually uses TCP ports 139 or 445 (depending on client and server Windows version). Network printing via LPR/LPD is on TCP port 515. Raw printing to many networked printers (such as HP JetDirect print servers) is on TCP port 9100. Again, this isn't a Squid issue, so you will likely get more useful help by asking on a different list. Adam
