Yes, good catch. This should be: oe_photo_12r_12x15in [HP20210302] >> oe_photo-14x18_14x18in [HP20210302] >> oe_photo-16x20_16x20in [HP20210302] > > As already noted, this would be “16R”. > >> oe_photo-22x28_22x28in [HP20210302] >> oe_photo-22r_22x29.5in [HP20210302] > > One reference gave “22R” as 20in by 29.5in, which makes no sense. Yes, the width is usually the number before the "R" (3R is the exception). >> oe_photo-24x30_24x30in [HP20210302] >> oe_photo_24r_24x31in [HP20210302] > > “24R” is elsewhere listed as 24in by 31.5in. 32in would make even more sense. Both of the following sources list 24R as 24x31.5: https://en.wikipedia.org/wiki/Photo_print_sizes https://mainthebest.com/sizes/24r-sizes/ which would be 7.5 inches larger than the width (just like 22R), so this entry should be: oe_photo_24r_24x31.5in [HP20210302] Unfortunately, I'm having a hard time finding a definitive source for the larger "standard" sizes... :/ >> oe_photo_30r_30x40in [HP20210302] >> om_photo-30x40_300x400mm [HP20210302] >> om_photo-30x45_300x450mm [HP20210302] >> om_photo-35x46_350x460mm [HP20210302] > > Is this the metric approximation of English 14x18 above? Yes, several of these metric sizes are close to existing English sizes, but not exactly. >> om_photo-40x60_400x600mm [HP20210302] >> om_photo-50x76_500x760mm [HP20210302] > > I’ve checked some photo print services, they are offering a poster size of nominal 50cm by 75cm, but not 76cm. Let's see what Smith can find out from his end... ________________________ Michael Sweet _______________________________________________ ipp mailing list [email protected] https://www.pwg.org/mailman/listinfo/ipp
