Whenever I print from Nisus Express I get hundreds of messages written to the console log, a sample:

I am using Nisus Express 2.5, MacOSX 10.4.3, and printing to a Canon i850 inkjet.
Other applications print without any problems.

It looks like these log messages are not being generated by Express itself, but rather by "Fenris". What is Fenris exactly?

Maybe?

'Fenris' is the machine's hostname I believe (similar msgs, not from NWX, in my console log show the hostname there). Those messages do seem to be coming from/triggered by NWX.

Geoff, have you checked for newer print drivers from Canon?

Looks like some kind of core graphics issue. I wonder if it's just some corrupted file? Maybe one that's diseased or somehow simply impure?

"Fenris" is my computer name (my PowerBook is called "Loki").
I am running with the latest driver from Canon for the i850 printer. These messages only show up when printing from Nisus Express, when I print from other applications, AppleWorks, NoteBook, etc. there are no messages.

I did some googling today for this problem and found the following on the SourceForge forum:

One thing that I noticed in the API-SUMMARY file for the CG reference
was to CGContextMeasureRTFTextInRect, which looks like it provides
similar functionality to AppKit's [NSString sizeWithAttributes:]
method. I googled for any documentation on this, but nothing is found
on it, so I thought I would give it a try anyway. The results it
gives seem to be correct, but it is throwing up a heap of warnings (I
guess - an error would stop the program)

CGContextClipToRect: invalid context
CGContextSaveGState: invalid context
CGContextSetShouldAntialias: invalid context
CGContextRestoreGState: invalid context
CGContextSetFillColorWithColor: invalid context
CGContextSetStrokeColorWithColor: invalid context
CGContextSetTextMatrix: invalid context
CGContextSetFont: invalid context
CGContextSetFontSize: invalid context
CGContextSetFontRenderingMode: invalid context
CGContextSetCharacterSpacing: invalid context
CGContextSetTextPosition: invalid context
CGContextShowGlyphsWithAdvances: invalid context

I think this is because the arguments don't actually take a reference
to a context. Should I just ignore this or is this method not
implmented properly?

The URL for this is: http://sourceforge.net/mailarchive/foru ... nth=200509

Don't know if this makes sense to the Nisus programmers?

Oops, that was a silly oversight on my part. Are we talking about the giant wolf Fenris then?

This is definitely a good idea. Please give it a try Geoff.

It does provide a clue that I'll be happy to pass along. Geoff, I gather this problem shows itself when you print any document? Even so, could you send me a sample document using the Help > Send Feedback mechanism? Thanks.

I'm posting this topic again to see if I can get it resolved. Whenever I print from NWE or NWP I get hundreds of errors in the Console and System logs for each page that is printed.
An example of the latest errors:

Oct 24 19:54:17 Fenris /Applications/Beta/Nisus Writer Pro 1.0.2 public beta.app/Contents/MacOS/Nisus Writer Pro: CGContextGetCompositeOperation: invalid context
Oct 24 19:54:17 Fenris /Applications/Beta/Nisus Writer Pro 1.0.2 public beta.app/Contents/MacOS/Nisus Writer Pro: CGContextSetCompositeOperation: invalid context
Oct 24 19:54:17 Fenris /Applications/Beta/Nisus Writer Pro 1.0.2 public beta.app/Contents/MacOS/Nisus Writer Pro: CGContextDrawImage: invalid context
Oct 24 19:54:17 Fenris /Applications/Beta/Nisus Writer Pro 1.0.2 public beta.app/Contents/MacOS/Nisus Writer Pro: CGContextConcatCTM: invalid context
Oct 24 19:54:17 Fenris /Applications/Beta/Nisus Writer Pro 1.0.2 public beta.app/Contents/MacOS/Nisus Writer Pro: CGContextRestoreGState: invalid context
Oct 24 19:54:17 Fenris /Applications/Beta/Nisus Writer Pro 1.0.2 public beta.app/Contents/MacOS/Nisus Writer Pro: CGContextGetCompositeOperation: invalid context

When I reported this error previously, I was using a Canon i850 inkjet (with the latest drivers). I have now upgraded to a new Canon iP4500, also with the latest drivers and the errors are still occurring. I can print with no errors to the same printer with Pages and NeoOffice. In fact, NWE & NWP are the only applications that cause these errors so I assume it is a Nisus problem (I have tried TextEdit - no problem).

I will send one of my documents to Nisus using feedback once I have posted this but don't think it will help.

Geoff

Thanks Geoff, I've received your documents. Unfortunately we are no closer to understanding the cause. We can't even reproduce the warning messages with the (non-Canon) printers we have in office.

As you may know, the printing and display systems on OSX are connected in a way that allows developers to easily create WYSIWYG applications. We write one set of code that specifies what you should see and OSX is responsible for translating these instructions for either your graphics card or printer as necessary. This is a great thing for us, but when something goes amiss under the hood it's hard for us to know the cause, especially if we can't reproduce the problem.

The most likely explanation is that something Nisus Writer is doing indirectly rubs your printer drivers the wrong way. Unfortunately that's all the information I have. Sorry to not be of more help.

I get errors like Geoff does whenever I print any document from NWP on any printer. The same documents printed from TextEdit or Jedit X do not give anything in the Console log. Here are some unique examples of errors, rearranged alphabetically. Each appears several times:

CGContextAddLineToPoint: invalid context
CGContextBeginPath: invalid context
CGContextClipToRect: invalid context
CGContextConcatCTM: invalid context
CGContextDrawImage: invalid context
CGContextDrawPath: invalid context

etc. etc. etc.

I'm glad I'm not the only one with this problem. I responded by e-mail to Martin today and mentioned that I had the same problem with the initial version 7.0 release of Adobe Acrobat Reader. I complained to them and they resolved it by version 7.03 or 7.04.
I use the console log to check that I have no problems with security or disks etc. But with the log filling up with these error messages it makes it difficult.

I am currently playing around with Pages to see if I can use that for printing Nisus documents but it's not a good way to do things.

Geoff

Thanks for the additional information- we'll investigate this further.

I installed NW Pro 1.2 today and tested the printing and it appears that this bug is finally fixed! I have been using Pages almost exclusively for the last year because of this.
