+ == USB -> Parallel adapter ==
+ 
+ We highly recommend not to buy and use these adapters to get old parallel-only printers connected to newer computers without parallel port. Please try the following alternatives:<<BR>>
+ 
+  1. First check whether the printer is really parallel-only. If it has a USB or Ethernet port, use one of these for connection. If you do not have free USB ports on your computer, use USB hub.
+ 
+  2. If you have already a USB -> Parallel adapter and you have an All-in-One router (or NAS) with USB port, try to connect the printer with the adapter there, if the router has print server functionality, your printer should appear as a network printer.
+ 
+  3. You can also get an old JetDirect (or compatible) network print box on eBay or Amazon for cheap, which also makes a network printer out of your printer.
+ 
+ Note that if the alternative you choose makes a network printer out of your printer that system-config-printer should find it as a network printer (wait for the scan to finish when the spinning icon disappears, then open the "Network printer" section). Perhaps you will need to choose make and model of the printer manually to finish the setup.<<BR>>
