Epson Photo 825 and CUPS - Print slightly off center, how to fix

[Peter Sebastian Masny <ps-list@masny.dk>]

Hi all,

I have CUPS working fine with my Epson Photo 825 printer (shared from a 
windows computer).  The (text) print is good but shifted about 4 mm to 
the left.  When I print the CUPS test page, the page frame edge is 
exactly on the top and bottom edge, but the right side shows the frame 
edge 4 mm in and the left side does not show the frame edge.

This is a problem because the first character of text printouts is on 
the left edge, "off" the printed page, making text printouts unreadable.

I suspect I would need to change some settings in the ppd for my 
printer, but the settings area rather cryptic.  I would hope for a 
single "offset" field somewhere, but there are pagesize, paperdimension, 
imageable area, etc for each type of paper in the settings, some with 
one coordinate set, others with two.

Anyway, has anyone else encountered this problem?  How do I go about 
fixing it?

Thanks

Peter
