This is a older style of router with printer server, as it can do not use IP address to access the printer port.
That's a virtual "LPT1:" port, not a real one.weiwei wrote: look under window XP for it driver, it creates a port which points to routers IP address and then LPT1 for printing.

Sounds good.weiwei wrote: 1. I selected network printer, then TCP/SOCKET, HP jDirect, RawConnection
2. I typed in my router's IP address
3. on Port, system assign port 9100 by itself.
Linux is not Windows. Linux is not MS-DOS. Using MS-DOS device names in Linux is not very likely to work. Besides: "port" here means TCP/IP port. 9100 tcp is the standard target port for UNIX-style network printing.weiwei wrote: I have tried many different setting on port, but none of them work. I tried LPT 1, LPT #1, lpt1, LPT1.
No, it's clearly your networking setup. Why not use the printer directly on the Linux computer? You can use Linux to share the printer on the rest of the network ... it's a server operating system after allweiwei wrote: But when I connect directly to the printer via Parallel cable, it prints fine. so the driver is not the issue here.
No idea, as I don't know that strange print server you have thereweiwei wrote:Under this condition, is it possible print to that router's print server?
