Canon never released official 64-bit drivers. If you’ve been scouring the web for a "simple download," you’ll mostly find dead ends or risky third-party sites. The Solution (The Tech-Savvy Way):
Canon uses a driver architecture called CAPT (Canon Advanced Printing Technology). The driver for the LBP 1120 is often shared with similar models like the LBP 2900 or LBP 3000.
Printing is extremely slow (one page per minute).
Official 64-bit drivers for the do not exist. Canon only released 32-bit drivers for this model, with support ending after Windows 7 (32-bit). Because this is a CAPT (Canon Advanced Printing Technology) printer, it relies heavily on software-side processing that is incompatible with 64-bit Windows architectures.
: Install a 32-bit version of Windows (Windows 7 or XP works best) inside the virtual machine.
: Set the printer as "Shared" within the VM network. You can then print from your 64-bit "Host" machine to the VM's shared printer. Method 2: Use a "Patch" or Third-Party Installer
