The printer
Printer performance, or throughput of the printer, is typically
stated in impressions per minute (ipm). It depends on several factors,
including:
- Mechanical speed
- Internal processing speed
- Attachment bandwidth
- Paper size
- Printer features
Duplexed pages contain two impressions, one on each side of a sheet of paper. N_UP printing places up to eight impressions on a sheet in duplex mode. For example, N_UP 4 duplex places four impressions on each side of a sheet of paper.
