Print Driver for Ricoh Aficio SP C430DN

[RexH]

I have a Mac running macOS 10.13.2 High Sierra and a Ricoh Aficio SP C430DN. When I print, I get gibberish 20% of the time. For example, it prints: ERROR: limitcheck OFFENDING COMMAND: xshow STACK: [7.881 7.236 6.501 0.0] (!"#$).

I have tried deleting the printers and reloading them, downloading the latest Ricoh print drivers, etc. Nothing works. Help!
