Photoshop CS6: I think that changing paper sizes and printers in the print dialog box should be a little quicker. I have used all the versions of Photoshop since v6.0 and this version seems like the slowest yet.
That shouldn't take much time at all -- but Photoshop has to communicate with the OS and printer driver when it makes some of those changes. If your printer driver is having problems communicating with the printer, or is slow for some other reason (bugs in the driver), then that could cause what you are describing.
Which OS version are you using?
Which printer model and driver version are you using?
Is the printer local, or on the network?
And isn't changing the paper size done entirely in the printer driver dialog, not in the Adobe print dialog?
I have this problem too. Is there any solution for this problem?
Hard to change printers and papers. What's more, this os dialog stuff cannot remember the last selected printer. Photoshop CS2 was the best...
