Sometimes, email attachments might print as a thumbnail view when printed from the email app.
If you see this, HP recommends downloading the attachment and opening it from its associated app or the program that supports that file type. (For example, a .doc or docx file extension opens in Microsoft Word, a .pdf file extension opens in Adobe Reader or Adobe Acrobat, and an .xls file extension opens in Microsoft Excel.) Then select Print from this App to send it to your HP Roam queue.
