Printing to HP1022 series printers from a VPN connected Mac requires a slightly tricky workaround as follows:
1 Download the driver package
This driver package needs to be downloaded & installed from http://support.apple.com/kb/dl907. It's unfortunately a very large download so a wired connection is good if available. A reboot is recommended for good measure.
2 Set up the printer
Open System Preferences > Print & (Scan / Fax depending on OS version)
Click the little [+] towards the bottom left of the window to get an "Add Printer" dialog box
Click the IP icon in the top-centre of the wndow and enter the printer's network name, followed by a .bioch.ox.ac.uk e.g. for printer lakp1 you should enter lakp1.bioch.ox.ac.uk
For Protocol, choose HP Jetdirect - Socket. Please note that this is not the usual way of doing things and should only be used for this particular series of printers
Pull down the "Print Using:" selection and choose "Select Printer Software..."
A long list of printers should be visible, enter a search string "1022" to narrow it down. Select "HP LasetJet 1022, 22.214.171.1241" and click OK
Click Add to finish installing your printer
