Probably. But SeaMonkey might do something a little differently or missing a 
code patch here and there. As said not the first time I experienced a print 
lockup after upgrading but overall its imho only Gecko code.

These are not used/set/reset in SeaMonkey code. -1 sounds like some sort
of default and is also used in Firefox.

Seems the print dialog and functions got a major update in Gecko 49
which corresponds to 2.46:

reading bugzilla id=1189846, it looks like these are major code changes 
related to printing, and much of it appears to be experimental.

Looks like we need to monitor this and look closer if it happens after the 
next update again.

I tested removing certain print related settings from prefs.js (about:config),

browser that hangs.


I found two categories of "print" settings in prefs.js
1. "print_printer", {printer name} and "printer_{printer name}", {value}
2. "print.print_printer", {printer name} and "print.printer_{printer name}", 
{value}


Category #1 (without the 'dot') seem to be irrelevant - I deleted all of them, 
and printing was still broken.


Category #2 (with the 'dot') are the settings that were causing the issue. If 
I delete all of them, I lose the old page setup parameters, but I'm able to 
print, and any new page setup parameters will be written back to prefs.js.


I also tried to narrow down the specific settings in category #2 that were 
causing the issue, and it looks like the "print_paper_{setting}" and related 
settings.


old settings that cause hang (but look correct)
print_paper_height, 11.00
print_paper_width, 8.50

new settings that work (but look wrong)
print_paper_height, -1.00
print_paper_width, -1.00

So there's an easy workaround for the technical user, but this is not a great 
upgrade experience for a non-technical user. Either way, a setting in prefs.js 
should not be able to cause a browser hang, it suggests parsing (and 
validation) of parameters is not as it should be. I'm fairly sure this must be 
related to recent changes to the SeaMonkey code, as it was always stable in 
the past.

Neither do I. Maybe they come from the OS or from choices we made in 
some dialogs like the Print dialog? Anyway, it seems to me that the new 
SM version interprets some of these preferences differently and 
therefore chokes on them. Resetting at least those settings that refer 
to page sizes, margins etc. can't hurt, IMHO. For me at least it did 
solve the problem. (I did not have this problem on my Linux PC, by the way.)

Hello,

like here ...
I don't have any problems, but I see tons of "user changed" printer
preferences what definitively have not been changed by me. May be there
are other processes which do those changes.

I wonder whether with 2.46 additional changes come and cause problems,
or whether these troublemaking changes have there been for a long time,
but started to cause problems with 2.46.

Personally I am thinking you printer driver may be the problem. And SeaMonkey
isn't that good cleaning up old drivers either. Backup your profile and go to
about:config. Search for print and reset every entry which is not the default

 completely. I had similar problems a while back with an older HP Laserjet.
There were several generations of drivers still in the Windows registry. Took

Yes this might cause problems. If you try it at least back up the profile
before and delete the storage.sqlite and storage dir from you profile after
going back to 2.40. But I would try to fix the problem. Its likely something
on your system alone because no one else reported a similar problem yet.

I have experienced this with 2.40 in the past.  If I pick another printer 
driver, I can usually get my print.  The biggest problem is if I try the pdf 
driver first and then try to go to my Canon printer, I cannot access that.  By 
using another pdf driver, I can usually get it and then the canon.

Do you have the doPDF application installed on your PC?  I found that
cancelling a print-to-PDF from SeaMonkey will disable further printing
of any kind from SeaMonkey.

Can you print from any other application on your PC?

When you try to print from SeaMonkey, do you see the proper
identification of your printer in the Print dialogue?

Have you tried shutting down Windows and then doing a cold reboot?

I am sure you tried all or most of these, but try them again.
