Hi All,

There is a problem while printing. Please review printer and printer template settings.

Have you shared the printer on the main server

Its a Customer Display unit connected to COM PORT 4.

It does not appear in the Printers and Devices Section, so not sure how that will work?

Ok I thought it was strange as dont see many printers on COM ports nowadays.

I assume the customer display works from the main SambaPOS terminal.

Remove the Customer Display print job from Settings->Terminals->Terminal Name for the Tablet.
SambaPOS - POS'n the World, one Terminal at a time.

Hi John, I will try this tomorrow and update here in the morning. Hopefully it will work. Thanks again.

Yes it works only on one terminal at a time. Hopeful John's suggestion should resolve the issue.

Unlike the printers, COM ports can not be shared between applications, and this is why you get the error. The only terminals that need the customer display print jobs are the terminals the customer displays are connected too.

Hi John

Problem still exists  >:(

In the Terminals section I have 2 terminals

1= TILL (which has the display print jobs)
2= TABLET (without the pole display print jobs)

I'm Running The Server Terminal on Windows 7 Ultimate with the Terminal Server Patch Applied, which allows me to log into Windows as a TABLET user.

The error appears just before the login screen into SAMBAPOS?

If the error appears before the logon screen, then it would be the Application Start Rule that shows 'This Section is Closed'.

In the associated rules for Application Start, Logon, Logout, etc that use the Pole Display, you can set a condition 'Terminal Name != TABLET' so the rules will not work on the Tablet, but will on other terminals.

Sorry, but it has been a while since I had these issues when using RDP.

John

You are a superstar. I would have never worked this out without your help. Thank you very much.

SambaPOS works terrific on a IPAD MINI via RDP app PocketCloud. Strongly Recommend it to anyone wanting to use a tablet to take orders.

Thanks again John!  :)

John, just realised after doing the above the customer display is no longer working on the Till Terminal Either? Any Ideas?

Are you using V2 or V3?

It shouldn't really matter. Take a step back, and remove the Terminal Name condition from the Logon & Logout rules and see if you can atleast get that working.

Are you sure each terminal has its own name set in Local Settings?

Hi John

Its V2.

To be able to change the local settings I'm guessing I need to make another local installation of SambaPOS? and run this copy on the Tablet so it will act as the Tablet Terminal and not conflict with the Customer Display. Correct me if I'm wrong?

After going back thru my configs, I am sure I only had to remove the print jobs from the RDP terminal name within Samba.

Does the Tablet RDP login using the same windows login as the Till or does it use another windows login?
If you are using a second windows login, did you login to that second account, install Samba and configure it as a separate terminal?
