For those using HP (tm) Inkjet AIO Printers for Photo printing, (there are numerous models), as a few examples herein: Models C10a, 7510, 7515, 7520, 7525 - they are "very picky" about feeding 4x6, 5x7 paper from their photo paper tray. Not so much the case for 8x10, or 8.5x11 out of the Main Paper Tray. The typical result of failures seen by these HP Printers after a no feed, or miss-feed is the message Paper Tray Empty. These repeated messages and failure to print is very frustrating and time consuming. People I've talked with have, or are ready to throw away their HP Printers. In my personal case, I've used Premium Photo Papers sold by COSTCO, and BJ's wholesale for several years. They are typically 60 or 70lb. rated Premium Quality photo paper for Ink Jet printers that states they are equal to the best photo papers buy the OEM Mfrs. - but they do not work all the time in these HP Printers even though you have set your "Printer Properties" to the correct firmware/software specifications.
Ah, at last relief - the HP Premium Plus Photo Paper 80lb. rated, feeds every time, after hundreds of Photos now printed with this particular photo paper. It is made in Germany, and available in Glossy or Semi-Glossy finish. The results are excellent. Yep, it costs more... but what value is your peace of mind while getting nice prints. We all want to save money when and where possible, but for those who enjoy printing their own photos, this product is worth every penny. WMB.
