thank you for your reply.
I confirmed that the user id and passcode is corrected.
I tested to print from the server. Not problem encountered.
The code comes up here as a 'invalid user'
Did you create a Local User Account?
I am connecting our SAP system to our printer through window printer server.
The printer is enable with local accounting and the model is ApeosPort-IC C4470.
I confirm that I enter the correct user ID and passcode in the printer server. I also did a "Printer test page", I managed to print the test page.
I confirm that I installed the correct printer driver in SAP system. I did a test with diabled the local accounting and I managed to print.
But When I enable the local accounting feature, and print from SAP system, it return error code 016-757.
From the documentation, the error code (016-757) identified as wrong passcode. But I was enter the correct passcode in the print server.
Any ideas what problem caused this error code?
