Samsung SCX-6545N, SCX-6545NX & SCX-6555 Printer Network Abilities

The Samsung SCX-6545, SCX6455 are part of a series of A4 monochrome multifunction digital copiers and printers. The copier-like construction and low running cost around 0.35p per page are part of the products attraction.

Copier-printers like this are normally shared by several users in a network and these machines are clearly intended for that, they come as standard with Gigabit - capable network and a hard disk for job storage.

The printers will default to getting an IP address using DHCP so if your DHCP server (usually embedded in the router) allows an address to be pre-allocated do that before plugging the printer in. Some routers tend to reallocate DHCP addresses even when told not to; if that could be a problem then give the printer a fixed address on the subnet outside the DHCP pool.

The printer control panel can be used to give an address.

Once the printer has an IP address the embedded Web server can be used for other printer setup tasks.

As with most recent printers these machines support TCP/IP Printing Protocols.

Samsung say the following:

Interface Ports
Samsung Network Printer Port Printing
TCP Port : 2000
Port Monitor installation
OS : Windows95/98/NT/ME
LPD (Line Printer Daemon) Printing
TCP Port : 515
OS : Unix, Linux, Windows OS (Win NT, 2K ~)
Microsoft Standard TCP/IP Printing
TCP Port : 9100
OS : Windows OS (Win 2K~)
IPP Printing Protocol
TCP Port : 631
OS : Windows OS (Win 2K~), Mac OS (MAC 10.3~)

Samsung have apparently invented their own print protocol running on TCP port 2000 to interact with their SyncThru software. There is no specific problem with this but other printer makers aren't likely to adopt it. It may conceivably conflict with Cisco SCCP (Skinny) part of Cisco Unified Communications Manager which can be used with their VoIP installations - not massively common, but not unknown. There seems to be very little documentation available on how the Samsung protocol works.

Port 9100 is generally regarded as HP Page Description Language (PDL) Data Stream (rather than Microsoft) and is most likely to be used; it can be used with Linux as well - probably with CUPS redirecting to it.

IPP is commonly used by Linux as well as Windows and Mac OS. The Linux CUPS implementation was written by Michael Sweet who was subsequently hired by Apple who also bought the CUPS source code. Apple develop CUPS.

Check the Syncthru Web Service (Embedded Server) to see what is available.
