printing 2 sided on my photosmart all in one printer

[ddb787]

I am getting this dialog box when I try to print 2sided: 

The Two-Sided option, Long-edge binding, is not available when the destination paper size is set to US Letter.

@ddb787, Welcome to the HP Support Community!

Which application are you trying to print from?

Have you tried printing different types of documents like PDF, Word or Webpages and check if the issue persists?

Let us try these steps to resolve this issue:

Install the printer using AirPrint driver

Please ensure that the printer is up to date with its firmware and Mac is up to date with its software. If you are unsure you may use the links below to update the printer firmware and Mac software:

Update printer firmware

Update software on Mac 

1.) Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

2.) Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer.

3.) If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button at the bottom of the list.

4.) Click the plus sign, click Add Printer or Scanner, click the printer name.

5.) Click the Use or Print Using menu, select AirPrint in the pop-up menu. Then click Add.

6.) Try to print.

Refer to this document to know how to print on both sides from a MAC.
