Hi ulap,
Thank you for providing that information.
I have provided a few things that we can try to resolve this issue.
From the application your printing from, go to file, print, Number of copies select 2. Uncheck Collate. You can now change the number of copies. Collate should now stay unchecked.
Try printing the multiple page document again.
If it still won't print the multiple pages then try the following steps to change the printer driver's spool settings.
Click Start, and then click Printers and Faxes.
Right-click the printer icon for your printer driver, and then click Printer Properties.
Click on the Advanced tab.
Click to select Print Directly to the Printer.
Click Apply and OK.
Try printing again.
If you are still having issues, the driver might have become corrupted or damaged.
I would uninstall and reinstall the printer software.
Disconnect the USB cable from the printer.
Run the uninstall.
Uninstalling the Printer Software.
Then download and install the latest drivers.
HP LaserJet Pro P1102w Printer Drivers.
Select your operating system, click next and click on the software to download and install.
Let me know if the multiple pages will now print.
Thank you for posting on the HP Forums.
Have a wonderful day!
