HP OFFICE JET PRO 7740

[EDOMOLETTI]

Good morning, I have an HP Officejet 7740 AIO printer and it works perfectly except for printing on A3 paper, it prints horizontal lines that are broken and diagonal, basically instead of printing like this " _____" it prints like this " ". I tried printing on A4 paper (which it prints perfectly) and then making a copy enlarged from A4 to A3 and the copy comes out correct, without issues, so I don't think it's a problem with the A3 format but something not configured correctly. I have aligned and cleaned the print heads, it has new cartridges, I have tried with multiple file formats but the result is always the same, it prints perfectly on A4 while on A3 it has this issue of the broken and diagonal horizontal lines. Can you help me? Thank you.

Hi @EDOMOLETTI, Buon giorno,

1. Please install the next driver software for your printer:

2. Restart your computer.

3. Then try again to print your document in A3 paper.
