We have a HP Laserjet 2550L connected to our XP PC by USB. We have now got a Windows 7 Home Premium machine and have tried to attach the printer using the Universal Printer Driver supplied by the HP website, but the printer is showing in the 'Unspecified' category in Devices and Printers.
During the installation process for the UPD, the 'Found Hardware' wizard gave two options - local printer (which stated not USB printers) and network printer - there wasn't a USB option?! We then selected the local printer option anyway and selected Virtual USB port and the UPD installation program said installed successfully.
The printer is still shown as 'Unspecified' but the printer software is there, as we can access the printer properties via print manager when trying a test page - unsuccesfully. The printer also doesn't appear in the list of printers in Word, etc.
Any help appreciated, Thanks.
