Re: [Trisquel-users] Connecting an EPSON Workforce WF 3640 Printer to Trisquel on Lenovo T400 Libreboot

As stated, you need a driver – specifically, the printer-driver-escpr  
package.  The NEWS file says your printer model was added in version 1.4.0.   
Trisquel 7 has version 1.3.0, while Trisquel 8 has 1.6.3, so you'll need the  
version from T8.  If you can't upgrade to T8, you could just install the  
single package from T8.  Installing binary packages from different  
distribution versions normally isn't recommended, but in this case the  
dependencies are met in T7, so it should work fine.
