I have a strange problem with printing a simple document on my Mac.

Generate the following document:

1. New document

2. Make a list with text entries (3rd button from left for lists, and  
chose default)

3. Enter "n1, n2" as the item header. (without quotes)

4. Enter "Test" as the text. (without quotes)

Now I can view the generated pdf or ps->pdf without any problem on my  
computer, and I can view the ps file without any problem using gs.

However, printing the pdf document from the 'Preview' app to our HP  
laserjet printers (two different ones... one B&W one color) gives an  
error:
ERROR: invalidfont
OFFENDING COMMAND: xshow

The problem seems to be the comma between n1 and n2. When the comma is  
removed or the format of "n1, n2" is changed to verbatim, the error  
disappears.

Printing the ps file directly produces no error. Actually, opening the  
pdf/ps file on the mac, and then printing it to a postscript file  
produces a file that when printed gives the error, and when viewed on  
the mac misses the comma, and viewed with gs gives: "Unrecoverable  
error, exit code 1"

This seems to be a problem with postscript creation on the mac, though  
it could also be a combined problem of TeXmacs+mac...
A diff between the two resulting postscript files (with and without  
the comma) is below... maybe you can spot the problem... I also added  
a diff of the original postscipt files and some analysis of the  
difference.

(Adobe acrobat on the mac prints the file correctly.)

thanks for listening,

Michael

------------

The problem seems to be the line starting with "gsave", and in  
particular, the entry
b(,)44
If I change it to
b(,)71
(which is what the verbatim format file has) all works well. But I  
have no idea what this means.
