Q: In a Windows NT4.0 machine. When try to add a printer port, there is no port type of LPR port to add.

A: Go to the Network in Control Panel. Click "Services" tab.  Make sure there is a "Microsoft TCP/IP Printing" service installed. If the Microsoft TCP/IP printing is not listed, you need  to add this service on.  After NT4.0 reboot, you will have the LPR port available to add.

Q: I have a Windows NT workstation with TCP/IP.  I send a job but the print job just sits in the queue, not to the print server.  How to troubleshoot this?

A: First of all, get the IP address of PrintSir. Click "PrintSir Status" tab in PrintSir Configuration Utility.  The 'Active IP' would be the current IP address of PrintSir.  For example here, IP address 192.168.10.15.  Then go to the DOS command prompt in Windows. Run the PING command.  For example, PING 192.168.10.15. You should get 0% fail rate and 4 success replies, otherwise, please refer the user manual to setup a right IP address for PrintSir.

Secondly, go to the property of the printer. Click the "Ports" tab, then "Add Port" button. Choose add LPR port. Put IP address of PrintSir in the  first field for the name of Print Server. Put lpt1 in the second field for the name of Print Queue. If your PrintSiris a three ports print server, you might put lpt2 or lpt3 as the name of Print Queue depending on which PrintSir port is connected to the printer. Finish the "Add Port" process. Click OK or Finish button. Then you can do a test print now.

Q: For PS3100A+. When I send print jobs to multiple ports at the same time, port 2 doesn't print until port 1 is finished.

A: This problem is not caused by the print server, it is caused by the spool system. A couple of System V Unix systems show the same behavior. Example of those systems are Solaris 2 and AT&T Unix and ICL System V. BSD Unix systems uses natively LPD and here it is no problem having2 jobs going in parallel. Solaris 1 is one example where it works. On some System V Unix systems LPD has been implemented as well (ask the Vendor) and here it will work. HP-UX is one such example.

Q: Using the LPR/LPD protocol from a Windows NT workstation causes some jobs to be halted for two to four minutes before printing is resumed.

A: In Windows NT 4.0 Service Pack 3 (SP3), the TCP/IP is updated. There are two new registry entries that allow line printer remote (LPR) to use any available port higher than 1,023. With these entries, LPR is no longer restricted to only using the 11 TCP Ports (721 through 731) and will not conflict with reserved ports, even on very busy print servers. TCP/IP printing (LPR) in Windows NT 4.0 Service Pack 2 (SP2) and earlier defaults to using TCP ports 512-1,023. In Windows NT 4.0 Service Pack 3, LPR defaults to using TCP ports 721-731, as described in RFC 1179 (Windows NT 3.51 Service Pack 4 and earlier versions). In addition, LPR in Service Pack 3 is now configurable through two registry entries, which enable the use of TCP ports 1,024 and greater. For information on setting LPR printers to be RFC compliant, please see the following Microsoft Knowledge Base article: ARTICLE-ID: Q141708 TITLE: Printing to LPD Printer Is Slow or Fails with Windows NT

Q: I can not find the print server on the network after configuring its IP address.

A: This problem occurs only when you have a NetWare server on the network and you configure some TCP/IP parameters without setting up the NetWare configuration at the same time. This problem was solved in firmware version of 7.6 (for both PS1000A+ and PS3100A+ respectively), please upgrade the firmware. 

Q: I send two jobs continuously, but I got a wrong print or garbage. It seems these two jobs are merged into one incorrect job.

A: The print server should be attached to a printer with slower speed. This problem was solved in firmware version of 7.8 (for both PS1000A+ and PS3100A+ respectively), please upgrade the firmware.

Q: What are the port names (queue names) for PS3100A+?

A: The port names for PS3100A+ are lpt1, lpt2 and lpt3 respectively.

Q: What are the port address (port number) for your print servers when printing on TCP/IP environment?

A: Our print servers support LPR/LPD printing protocol which port address for TCP is 515.
