PRINT SERVER OVERVIEW

The purpose of this document is to give the user an overview for integrating the ZebraNet PS 4000 Print Server

into their environment.

The ZebraNet PS 4000 Print Server is a transportable printing system providing connection of up to 4 printers.

The system comes in a variety of configurations including:

• Stand alone print server providing connections of up to 4 USB or serial printers.

®

PS4000 Print Server

• Print server pre-configured with Zebra direct thermal or thermal transfer desktop printers.
Figure 1 shows a particular configuration of the print server with three 2 inch direct thermal Zebra printers.

Communication

The ZebraNet PS 4000 Print Server appears to a host computer as one IP address with the individual printers
having unique port numbers. Therefore, printing is accomplished by directing print jobs to a particular printer
through an IP address/port number combination.

ZebraNet

Programming Manual

Configuration

There are two areas of configuration for the ZebraNet PS 4000 Print Server: print server configuration and
individual printer configuration.

Print Server Configuration

Print server configuration involves configuration of the print server making it available on the target network.
This involves configuring network settings such as IP address, SSID, subnet mask, gateway, etc.

®

PS4000 Print Server

Individual Printer Configuration

Individual printer configuration involves settings for the individual printers. These settings include: port
number, baud rate (serial printing only), and language (CPCL, ZPL, or EPL).

The Print Server Configuration Manager provides an easy interface for configuring the print server. This
application is described in Section 2.

Print Server Integration

Integration of the ZebraNet PS 4000 Print Server involves configuring the server with the appropriate IP settings

for the target network. Once configured, the printer exposes the connected printers through unique port numbers.

Programming Interface

Interfacing to the individual printers from a host application involves two parts: TCP/IP communication for the

actual sending/receiving of data and knowledge of the target printers since each printer type supports its specific
control language. References 2 and 3 describe the printer control language for EPL and CPCL based printers,
respectively.

TCP/IP Communication

®

PS4000 Print Server

The individual printers are accessible via a unique IP address/port number combination. All four printers share

the same IP address but are distinguished by their unique port number. The print server simply acts as a ‘pass­through’ between the host and printer. Therefore, any communication with a particular printer must use the control
language for that printer.

EPL Printer Programming Example

The following is an example format file for an EPL base printer. Sending this data over the network to the IP

address/port number for an EPL printer will result in a printed label.

Set/Get Commands

The Print Server supports the set/get interface for setting and retrieving various settings such as IP address,

SSID, etc. The suite of set/get related commands are identified in the CPCL Programming Language Manual,
available on-line at www.zebra.com. There are also set/get commands specific to the print server identified in Section

3.
A simple set/get example – printer port number:

Next S ect.

Set the port number for printer 1:

! U1 setvar “print_server.printer1.ip_port” “6102”

Get the port number for printer 1:

! U1 getvar “print_server.printer1.ip_port”

Zebra Port Driver

Communication to a printer requires installlation of a printer driver. Once this installation is complete, the Zebra

printer port driver is used to map the printer driver with the corresponding IP address/port number. This facilitates
communicating to the printer from a host PC.

utility providing an interface to perform the initial
network setup as well as maintain the network
configuration of the print server.

This application is dialog based where the main
dialog, or ‘Main Menu’, allows navigation to all
related functions. The main dialog is divided into
the following areas:

Network Setup – The operations available
under Network Setup allow the user to perform
all network related configuration and status for
the printer server. The ‘Network Setup’ buttons
include the following:

• Quick Network Setup

• Network Settings

Printer Server as well as configuring the individual printers connected to the printer server. There is also an option
to create a standard TCP/IP port in order to print from a PC to a printer that is connected to the Print Server. The PC
/ Print Server buttons include the following:

• Com Port Setup

• Print Server Settings

• Individual Printer Setup

®

• Port Driver Setup

File Management – The operations available under ‘File Management’ include the ability to send and receive

files on the printer server as well as the ability to send files to the individual printers connected to the printer server.
The ‘File Management’ section includes the following buttons:

• Send Files (Print Server)

• Read Files (Print Server)

• Individual Printers
The default operation of this configuration utility is to communicate with the printer via the serial port. Prior to

doing any configuration of the print server, confirm the serial port baud rate used by this utility matches that of the

printer. To check the baud rate used by this utility,
select ‘Com Port Setup’ from the Main Menu.

Quick Network Setup

The ‘Quick Network Setup’ option walks the user
through a series of dialogs that enable the user to
select the network related settings of the print server.
Following are the screens associated with ‘Network

Indicates if the Print Server should poll printers
for data coming from a printer.

With this set, the Print Server will periodically
ask connected printers for any data. The
server does this by issuing a USB BULK-IN
request. If a printer is bidirectional, the only
way the server knows if there is any data
coming from a printer is to request data.
