Spencer, thanks, again, for the reply.
I looked at comparable All in One printers from Canon, Epson, and Brother, and ALL of them have scaling in their print driver's "Print Preferences" dialog box. But HP does NOT. In addition, I was easily able to look at their documentation online to actually see visual and textual descriptions of this dialog box--something that I cannot find with any of the current/comparable other HP printers.
You don't have to "transform" anything. Pretty much every software program accesses the print driver in Windows and allows you to select your Printing Preferences for that print job through the printer software. If the driver includes a scaling/resizing option then it is EASY; if it does not (Like HP's driver) then you have to conjure up some wizardry to try and get it resized (like print it full size, then copy it on the printer with the reduce scaling--but this wastes an extra page of paper and ink).
I don't have time for wizardry every week when I print my work schedule to approximately 75-80% scale...I returned this HP 8600 printer yesterday and purchased an Epson Workforce 3540: couple more features for about the same price. And I can keep the magic wand in the breast pocket of my wizard's robe when I need to scale my print jobs.
