Yes, Old Toad, I am trying to print from iPhoto. (If you have to ask the meaning of CRS, you must already , since I believe you're older than I am, have it, Can't Remember S%$#.) I will give the HP application a try as soon as I find my manual in my drawer. Found it, no, nothing in it. The last time I am sure I did collages, I was still using my eMac, and an Epson printer. I used AppleWorks Painting. I had been trying to create pages of family pix to send to my sibs. You helped me out then. BTW, they came out great. The Epson had multiple creative apps, as did the old iPhoto. Hmm, Page Setup isn't under file anymore, dang. That's where i used to be able to choose multiple photos per page? Oh, phooey. Give me back my ancient iPhoto! I now recall the last time I printed multiple photos on one page, without borders, with my Windows laptop. I am not setting that whole thing up. I can print single photos per page, or do a contact sheet, enlarging the photos using the column slider to lower the number of columns, thereby enlarging the pix, but I can't get them to come out very big. Well over an inch of white between the pix on my letter size paper. Doesn't resemble a collage at all. I was going to add a photo of one collage, but I just found out the pix of my creations aren't even in my current iPhoto library, yikes! I have some work to do.
