Canon has divided the world into 8 regions and the last or second last digit in the type number is region dependent. I think the last digit in the type number suggests that the printer is intended for use in North America meaning USA and Canada. Checking Canon US the printer is no longer supported and no driver is available,
But Canon Europe has a driver for PIXMA MX435 which I think is the same printer as the MX432 but for use in Europe in stead of North America. I think that driver will work with your printer. Notice that the driver is for the MX340 series of printers suggesting it is intended for all regions. I think it will also work if your OS is Windows 11, even if the driver officially only support OS up to and included Windows 10. Here is a link to the driver.
Here are the 8 regions:
Region 1 for South American and Mexican markets
Region 2 for North American market = USA and Canada
Region 3 for Japanese market
Region 4 for Middle East, Russian and African markets
Region 5 for European and Australian markets *)
Region 7 for Asian market
Region 8 for Chinese market
*) With the introduction of the PGI-x50/CLI-x51 cartridges Australia and New Zeeland got their own region 6:
PGI-650, CLI-651 C/M/Y/BK/GY
