I purchased a HP Officejet 250 All-in-one mobile printer and installed the full software onto my Toshiba Tecra W50.  The printer is wireless and connects onto a network or by WIFI Direct.  When I go to print documents nothing will print.  I called HP support and they troubleshooted for over an HOUR with me and concluded that it's a computer hardware ISSUE.  They said they tried installing other printer drivers and it won't install other printers either.  They think it's some hardware issue with the Toshiba laptop that is preventing printer files from being accepted and installed.  One thing I don't understand is why does it seem the printer and laptop are communicating through network because it's being recognized.  But problem is it won't print.  I cannot call Toshiba because they don't have a 24 hour Tech support line.  I'm on a deadline and need the printer ASAP.  Can you please help me resolve this issue?HP Officejet 250 review:

Here is my best advice if on a dead line. Run to the nearest office supply store with a helpful tech person. Ask him or her to print a document for you as a DEMONSTRATION. Have the document in PDF format on a USB stick.

Can yu get to the wireless printer with your SMARTPHONE? Send the document to your smartphone  an attachment to an email. Again, try PDF as the file type.

As an alternative to PDF, used RTF.
Has the printer ever worked for you?

EDIT: Are you in a hotel? Do they have a printer you can get into over the local wireless? Can you send your document to the  hotel  as a FAX?

The above might help if you don't already have a FAX service.
