#27432 — Stranger printer happenings?

I wrote a little program for the local animal shelter.  The program 
prints a poster for lost or found animals.  When I wrote the program and 
tested it at home on my printer, an HP LaserJet, it worked fine.  When I 
got to the site to test the program, the result from the printer 
appeared to be scaled up by a factor of 2 in the x direction.  The 
PageFormat was in portrait mode and the other PageFormat parameters 
looked perfectly normal.  Turns out scaling my rendering by 0.5 made it 
print fine.  Anybody ever see anything like this?

Thanks,

What printer (vendor & model) does the shelter have, and what printer 
driver?  What OS are you each using?

Contact the printer manufacture with this information and ask about 
possible incompatibilities.  There maybe other issues (bugs) or APIs 
which you are unaware that could be affecting output format.  You can 
try talking to Oracle too but generally I've found them unresponsive to 
small developers.

Could you post a sample of the printer code?  Stefan raises a good point 
that the issue could be in your code as well.

I don't have the printer manufacturer.  It is a color ink jet printer. 
The OS is Windows 7.  The print code is below (with the AffineTransform 
to make it work).  It prints fine on my LaserJet under Windows 8.

Thanks,
