It seems that there is no driver available,
Can you describe the seemingness in more detail? What did you do; what happened; and what didn't happen?
What were the error messages?
The 5100 should run fine in Mavericks. In fact, it will run fine with a Generic PostScript PPD. No special "drivers" needed.
On the PREFERENCES > PRINTERS AND SCANNERS window, the printer is here show as inactive, with a green light.
But when I try to print out (even a really light document), the light turns orange, saying that the printer is working.
On an other window, it says "printing on - connecting to the printer"... but nothing happens.
I've also tried with the driver rcommanded by Esquared… same non-result.
Could you please help?
