/pffs (or pffs:)
The power fail file system is used to store files that need to be saved when the
printer is turned off. Files stored in this location cannot exceed 256 bytes each. The
total size of the “pffs” unit is 32 KB.
/rom (or rom:)
This device is used to store a collection of files that are available by default in the
printer, for example the default web pages, fonts, and images.
/rom/images (or rom:images)
This directory is used to store images used for the default web pages.
/rom/secure (or rom:secure)
This directory is used to store the password protected web pages.
/tmp (or tmp:)
This is the printer’s temporary read/write memory. Files in this location are not
saved when the power is turned off or if there is a power failure. Do not store valu-
able data in this location. You may want to use “tmp:” instead of “/c” to temporarily
store data, because data can be written to SDRAM faster than to the flash memory.
Customizing the Printer Home Page
The easiest way to modify the appearance of the printer web page is to create an
HTML file called “INDEX.HTM” on the device “/c” with custom designed logo and
colors. From this file you can easily link to the printer configuration pages. The web
server generates these web pages with dynamic information on the fly. This pro-
cess makes the real-time generated pages of the printer appear in the Honeywell
style. The colors and logo of the customer are ignored.
Web Style Guide Files
The printer network cards customizes the default web pages by changing the con-
figuration of the engine that generates the pages. While generating the pages, the
web server accesses configuration parameters, like the background color, the
name of logos to display on the page and generates the HTML code. Default con-
figuration of these parameters makes the printer’s web page appear in the Honey-
well style, with corporate colors and logos. When changing the parameters, the web
pages are permanently customized.
Customization of these parameters has to be done in specific files called “Web
Style Guide Files” , assigning user-defined values to several support environment
variables.
