I continued to use the same (old!) printer after I got a new computer loaded with Win7. Just downloaded new drivers for it. It was trivial. I can’t believe Adobe doesn’t have an upgrade available for PhotoShop for Win7.
My ex uses PS professionally every day. I’ll ask him how he dealt with the change for you.
I could print text with the old printer and vista but could not make adjustments or run cleaning cycles.
Without the ability to set preferences you just waste photo paper. I set the printer to match a color chart and a Pantone Huey to set the monitor. If it doesn’t all work together print quality is all over the place. Photoshop version 7 is old stuff but it works fine. there aren’t any upgrades. The printer is the problem anyway. It’s taken a long time to accumulate software, I can’t afford to start over.
