HP Photosmart 7520-MAC - Incorrect Paper size when printing checks on Checkbuilder pro

[Klbster]

I have an HP Photosmart 7520 printer and use a Macbook Air.  When printing checks on Check builder Pro, periodically i get the message that the paper size is incorrect and the sheet of checks will not go through.  I have tried deleting the printer driver and reloading it as instructed in a prior solution and which has worked before, but now nothing changes.  Also, when I re-add the printer driver and select Use it gives me the option of Airprint or the name of the printer.  When I select the name of the printer (as instructed in the solution) it gives me a message "inkjet4.driver" will damage your computer.   When I proceed and try to printer a regular document it says "PDE.plugin" will damage your computer,   "commandtohp.filter" will damage your computer, and then it cuts off the printing process. So I can only printer regular documents after selecting the Airprint Use option when re loading the drive, but then cannot print checks.  Please advise

I reviewed your post and I understand that you are facing issues printing.

Don’t worry, I assure you I will try my best to get this sorted.

What is the Mac OS version you are using?

Meanwhile, I recommend you remove the printer and then download the driver from the below link and then add the printer again and check if it helps.
