How to setup Winlpd for printing to HP LaserJet 1000 and similar printers.

When you set up HP LaserJet 1000 printer the setup software installs two printers "hp LaserJet 1000" and "hp LaserJet 1000 DOS". To be able to print using Winlpd you should add the "hp LaserJet 1000 DOS" to Winlpd.

This approach will also work for other cheaper HP DeskJet printers including USB printers.

Windows Dialup networking starts dialing when I print using Winlpd LPR client.

You have the Internet explorer set to dial out automatically, unfortunately Windows 98 starts to dial out even if there is a request to connect to a machine on your local network. Solution to this is to turn off certain entries in the registry.

If you wish that the dialup networking be not started for other applications you can rename the two key names from the registry.

This will stop it from trying to connect when you try to print. You internet explorer will keep dialing out when you try to access the internet. You can start REGEDIT from Start/Run menu and got to the following key. Right click and rename the two "Auto*" names.

Windows98

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock\Autodial

Name Value
------------------------------------------------
AutodialDllName32 wininet.dll
AutodialFcnName32 InternetAutodialCallback

How to configure my network if Winlpd PC has a private IP address behind Windows ICS or a NAT device.

Most NAT implementations allow connection coming on particular port (515 for LPD) to be redirected to one private IP address. So this will have to be configured in the NAT server. You will need to redirect TCP port 515 on your NAT or ICS Server to the private IP address of the Windows PC running Winlpd. For more information about this read the ICS documentation in Windows.
