My HP DeskJet 720c has suddenly stopped printing anything from my newish Mesh computer (Windows XP)though it has worked fine for six months and still works perfectly OK on our older computer (Windows ME).
The only significant event immediately prior to this failure was the installation of Microsoft Office (Student and Teacher edition).
The printer connection is to the one parallel port on the computer (LPT1) and the connection is sound.
Looking at 'Device Manager' there appear to be no LPT ports listed - only COM1 and COM2 are listed. How can the LPT1 have disappeared? How can I get it back, please, does anyone know?
Just before your email I went into the BIOS and altered the printer port setting - printer now seems to be working. Thanks for the advice - you were on the right track! Its's the first time I have altered anything in BIOS - not as scarey as I thought.
