I'm a graphic artist and recently purchased a Hawking print server to house my 3 printers. I had a professional tech hook everything up ... he printed a couple of test pages, then a few text pages ... all 3 printers worked and he left. Later when I tried printing my higher resolution graphics ... not one of the 3 printers would work ... they just give me error messages. I tried plain text again ... and it works. Is there some kind of setting for high resolution work?
