From the Canon S450 driver for OS X readme:
BJ Printer Driver
- This printer driver cannot be shared with other printers by the network.
- This driver does not support the banner and custom paper printing supported by the Mac OS 9 printer driver.
- This driver does not support the Photo Optimizer PRO, Simulate Illustration, and Monochrome Effects functions supported by Mac OS 9.
- This driver does not display the low ink warning and BJ cartridge mismatch error that are displayed by the Mac OS 9 printer driver.
- The print queue button in Print Center malfunctions dpending on the click timing.
- The print position may deviate or the scaling function may malfunction depending on the type of application software.
- When an application that runs in the Classic environment is used, communication with the printer could fail. If this problem arises, cancel Classic in [Classic] in [System Configuration]. If the same problem persists, disconnect the USB cable and then reconnect it.
- When making settings in the [Page Setup] dialog box, be sure to select your BJ printer model from [Format for]. If you select any other printer model, printing could fail.
BJ Printer Utility
- When an application that runs in the Classic environment is used, the BJ printer utility does not run normally.
- If this problem arises, cancel Classic in [Classic] in [System Configuration]. The BJ printer utility will run normally.
- If the printer model is not displayed in the printer list even after Classic is canceled, power the printer off and on again or disconnect the USB cable and then reconnect it.
It’s almost like the team that wrote the OS 9 driver had to write the readme for the team that wrote the OS X driver. Not that I’d really call it much of a driver, if the readme is any indication… The original has trouble printing from Freehand (and apparently Word, but I haven’t tried), so if this will fix that, I’ll call it a win. I never print anyway, so it’s mostly academic. Still, bastards.
…And they didn’t even put the text in pretty HTML so I could just slap it in. Bastards.
