Hi Alternaut,
I don't think it's a font issue because it sort of looks like a watermark. But the squares appear in lines and some are smudged. Their size is about 1/2 inch by 1/2 inch and are B/W in color. It seems to be more of an issue with actual printing as opposed to any coding in the file being printed.
The printer is about 2-3 weeks old and has printed about 4-5 pictures and less than 100 pages of b/w text pages. The ink cartridge is the cartridge supplied by Lexmark in the box and haven't tried a fresh one b/c they are so expensive.
The squares started to appear on last friday (11.5.10) after several good print outs.
Drivers are from the cd provided by Lexmark (ver 1.01 i think) and I recently updated the printer's firmware as well. The problem has not been corrected.
Hope this helps.
