Authenticating on the Konica Minolta printer


The Personal Printing Client for Konica Minolta printers is not installed directly on the printer, but rather, as a Windows service on a separate computer; this can also be the Per­sonal Printing server. The Windows service sends the Personal Printing Client's code, and it's settings, to the OpenAPI on the printer. There, the Personal Printing Client can be used for authentication at the printer and to display the list of print jobs. The advantage of this solution is that a group of printers can all be configured simultane­ously at a central location.

Generally, communication between printers and the Personal Printing server is achieved via the Windows service of the Personal Printing Clients for Konica Minolta. The Personal Printing server only communicates as the print server for receiving and sending print jobs. It communicates directly with the applications that the jobs are being printed from, and with the printers.PIN or NFC card authentication on Konica Minolta printers

Installing the Windows service

The Personal Printing Client for Konica Minolta printers can be installed on the fol­lowing systems:

  • Windows Server 2008 and later
  • Windows Vista and later
  • incl. .NET Framework from version 4.5

All Konica Minolta printers from Open API v4.5 can be used.

  • Request the Personal Printing Client for Konica-Minolta from ThinPrint Customer Support.
  • On newer systems, cancel the automatic blocking of the file PPKMClient.exe by clicking on Unblock in its file properties. Windows blocks executables down­loaded from the internet or other sources automatically.clicking Unblock to cancel the file blocking

clicking Unblock to cancel the file blocking

  • Copy the client software into a directory on the computer that you want to install onto. The installation uses installutil.exe from .NET Framework; you must therefore specify its directory, such as:

c:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe

  • Open the command prompt, switch to that directory, and run the following com­mand:
installutil.exe -i :\\PPKM­Client.exe

You will then find the service in the Windows services folder. It uses Auto­matic start up, but has not yet started.

  • Therefore, start the service manually.

Preparing the Konica Minolta printer

Before we can configure the Personal Printing Client, the printer(s) must be made ready to communicate with the Personal Printing Client. To do this, open each printer's web interface and then enter, or check, that the following settings are in place:

> in Network→ OpenAPI Setting:

Port No. (SSL) = 50003
This is required because the printer app only allows encrypted communication for the OpenAPI. Confirm twice with OK.

a printer’s web interface: OpenAPI with SSL-TCP port 50003

a printer’s web interface: OpenAPI with SSL-TCP port 50003

> in Security→ SSL Setting:

Mode using SSL/TLS = Admin. Mode and User Mode
This is also needed for encrypted communication with the Windows service. Confirm twice with OK.

a printer’s web interface: select SSL modea printer’s web interface: select SSL mode

> in Security→ External Certificate Setting:

  • Provide the root certificate of your company's CA (or another issuer's certificate) for authentication of the Windows service on the printer. Select Trusted CA Root Certificate (or one of the other options), and then import the certificate, using the New Registration option. Confirm twice with OK.

> in User Auth/Account Track→ Print without Authentication:

Print without Authentication = Full Color/Black or Black only
Otherwise – i. e. if Restrict is selected – the printer wouldn't accept printing jobs from Personal Printing. Confirm twice with OK.

a printer’s web interface: Print without Authentication must be set to Full Color/Black or Black only

Special case Proof-of-concept

For the authentication of the Windows service on the printer within a proof of concept that uses one printer only, instead of importing the root or issuer certificate, you can generate a self-signed certificate for the printer.

> in Security→ Device Certificate Setting:

  • To generate a self-signed certificate for the printer, select New Registration.

a printer’s web interface: machine certificates installed

a printer’s web interface: machine certificates installed

  • Then select Create and install a self-signed Certificate.

  • You then export this certificate, using the Setting (see above). Select Export Certificate. Confirm twice with OK.

Configuring the Windows service

Starting PPKMClient.exe (without parameters) will open the configuration console of the Windows service Personal Printing Client for Konica Minolta Printers. A shortcut for this purpose should be placed on your desktop.

The console for the Windows service contains the following fields (described below):

  • Personal Printing (Settings that the service requires to communicate with the Personal Printing server)
  • Service settings (Settings that the printer uses to communicate with the ser­vice; the service sends these to the printer beforehand, using Register)
  • Credentials (User names and passwords, with which the service is authenti­cated to the printer)
  • User authentication modes (Settings for authenticating users to the printer: with NFC card only, with NFC card and PIN or with PIN only and the setting for which number or character groups of the card number should be used)
  • Printer setup (List of Printers – with specific settings, if applicable - to which the service sends all the settings en bloc)

Personal Printing

Menu itemFunction

Default PIN• is the same for all users and printers
 with self-registrationmust be the same as the Default user PIN in the console of the Personal Printing server, e. g. 0000
 • with manual setup by the admin: must be the same as the User PIN in the users’ AD configuration on the Personal Printing server
Certificate issuer name (optional)• name of the root certificate or issuer certificate, if the cer­tificate installed on the Personal Printing server is not one purchased from a public certification authority, but is instead, a web server certificate from your own CA

Authenticating on the Konica Minolta printer

  • For sending a print job to the Personal Printing server see the section Authenti­cating on the Lexmark printer.
  • When printing, the KM printer’s home screen is used for authentication. To login, the user must hold his or her NFC card or NFC token up to the dedicated reader, located below the display.
