Need help - AC Adapter for RS 26-3591

[Ren]

Can you solder?
I have no idea if the barrel (power) connector of the Amazon power supply will fit your printer, but a proper size one could be soldered on.
The 4.8 volt or 5 amp output of the Amazon power supply should not be a problem. The printer will hopefully draw only the amperage it needs. As it has AC output, (I couldn't really tell even when I enlarged the Amazon photo), polarity of the barrel connector shouldn't matter. 2.4 W / 4.8 V = 0.5 Amp, so the power supply could provide 10x the power the printer is slated to draw. That would be a consideration if the printer has a defect causing it draw far more than the slated current. (i.e smoke!)
