No significant record of problems with Aficio 1045 or 3045 either PCL or RPCS.
Problems started with using PCL drivers for Aficio MP C5000 colour copier with popup user code customisation by Ricoh NZ. Some users had difficulty printing from Word / Publisher etc but OK when file converted to PDF and printed in Adobe Reader.
After 64 bit driver was added all Windows 7 users started having problems with all printers.
After popup and standard PCL drivers were updated to latest version 3.2 many users had printing problems.
Currently are working around by deploying RPCS drivers with hardcoded popup codes which is working for Windows 7 users & will be deployed to all users.
