1. We highly recommend that a qualified engineer clean your franking machine when switching between red and blue franking ink or vice versa. Switching franking ink types without professionally cleaning the machine may cause damage to the machine.
  2. Please also note that this model differs from the Pitney Bowes DM300 and is compatible with a different set of cartridges. Unfortunately we do not sell cartridges compatible with the Pitney Bowes DM300.

Pitney Bowes DM300c Printer Review

Expert review of the Pitney Bowes DM300c printer 04 December 2012

Our Verdict:

The reliable Pitney Bowes DM300c digital franking machine is ideal for small businesses with high-level mailing needs. This franking machine has a semi-automatic envelope feed and can handle media as large as 330 x 381 mm. It delivers professional output with solid texts and even images. The Pitney Bowes DM300c mailing system comes with LAN connection to provide services like software updates and postal rate changes. This unit does not offer dimensions-on-the-way function.


This compact franking machine comes in blue and beige enclosures. The central unit comes with function buttons, a numeric keypad, and a monochrome LCD display. A weighing scale is on top and feeders and stackers for envelopes are on either side. For connectivity, LAN is built-into the Pitney Bowes DM300c. This franking machine has a speed of 65 lpm and can handle integrated weighing options of 5 kg. The Pitney Bowes DM300c measures 370 x 435 x 315 mm and weighs 10.4 kg.


The Pitney DM300c franking machine delivers good quality output and can even download and print company logos. With its built-in LAN connectivity, the Pitney Bowes DM300c printer offers quick access to postal rates. The DM300c franking station has automatic time and date settings and smart metre for VAT services. To make cartridge replacement cheaper users can purchase compatible Pitney Bowes DM300c franking ink which is a lot cheaper than the original red 765-9RN inks.


Dimensions-on-the-way functions are not offered with the Pitney Bowes DM-300c franking printer. The optional upgrades are quite pricey.
