Suddenly can't print to an HP 6500 all-in-one printer. Color JPEG file, letter size 300 dpi. Have re-installed printer drivers and reinstalled Photoshop CS5. Other applications will print to it OK. Any thoughts? Mac OS 10.6.8

Why can't you print? Is there an error?

Chris!
Thanks for the quick reply.

No errors show. It is as though it spooled the image, but that the image never got to the printer. The same printer will print other application documents immediately before and after the Photoshop attempt. It used to print Photoshop documents with no problems. It makes no difference if I change images and formats. If I switch to a different printer, it will print the desired file from Photoshop. Maddening.

That means that Photoshop is spooling the data to the OS printer driver, but somehow between there and the driver or the printer, it's lost. (the file format, etc. don't matter - Photoshop prints the same bits regardless of how it got the bits)

That isolates the problem to the driver, or the connection to the printer itself. Since other applications can print, that means that the printer connection is ok, and that only leaves the driver.

Since different applications can use different printing paths (Cocoa, Carbon, simplified, color managed, etc.) that can actually use different parts of the print driver code. It could be a damaged file, or a bad setting/preference.

You could look for the printer driver preferences (probably in a plist file) and try resetting those.
You could also try resetting Photoshop's preferences, in case the driver stored some bad settings data with Photoshop (which will get reused as the defaults for that printer).

Beyond that, you'll have to talk to HP about how to troubleshoot their driver.

I have solved the problem. I changed USB ports for the printer and it printed OK. I then went back to the original USB port and it printed OK. I did this because I have seen similar fixes for USB keyboards and mice. It is as though the computer and Photoshop forgot the printer was on the port and had to be shown where it was. I believe Apple had a note on this, or it was mentioned in a Mac magazine I read somewhere. At any rate, the problem is solved.

I thank you for your time and thoughts in this. It is greatly appreciated.
