I corrected Project field, Version field and Area field as Sysop.

Could you please attach sample project to reproduce your issue?

I don't know how to add a comment to an already submitted report.

All you need is a form with a button and a memo with some text in it. Add the code I submitted to the buttons onclick event.

You are able to modify your report via Windows Native Client or Web client.

So, we can reproduce your issue with quite simple code. Thanks.

What could be simpler than what I have already told you?

This error appears to occur for any string with Write or Writeln, so the contents of the memo is not important. Not resolved in update 2. The problem may be that the printer is not being set up for the specific (or any) stream type before System._WriteBytes if called.

THIS IS A CRITICAL DEFECT AND SHOULD BE HANDLES WITH MORE URGENCY.

A large amount of code from previous versions does not work and there is no adequate workaround.

Note: the compiler appears to use asm rather than compiled pascal code (for AssignPrn), but this is nor reflected in printers.pas. Is it possible that the distributed printers.pas is not up to date?
