Looks like I've cracked it [Touches wooden desk]. Need a USB to IEEE 1284 36-pin Parallel Printer Cable, like the one I received today (ordered yesterday from www.cables2u.co.uk
). First, connect it to Z11. Turn on Z11 and boot up Vista PC/laptop. (I run Vista Business on my laptop.) Connect cable to computer. Message appears "Installing device driver software". Click it for status. 'Found New Hardware' box appears. Click 'Locate and install driver software'. A message appears "Error loading LXADSUI.DLL. Specified module could not be found". Click 'OK'. Message appears saying driver software installed successfully. ["Yeah, right ..."] (Have faith, folks!) Now, click Start, then Control Panel and double-click Printers. Right click on Z11 and click on Set As Default Printer. Right click on Z11 again and click on Properties. Check on Ports tab that Port USB is ticked for Z11. On Cartridge Maintenance tab, check right cartridge is showing. If not, click 'Install/Change Cartridge' and follow instructions. Then 'Clean Print Nozzles' and 'Align Cartridges'. Check settings on the other tabs in Properties look OK and try printing a test page! It looks good to me!
