Printer Categories

PSF 4.4.0 is priced in Cumulative Block Tiers. The PSF tier is determined based on the number of printers PSF will be driving and the impressions-per-minute (IPM) rated speed of those printers. Printer points are assigned to each printer, then accumulated. The total number of points indicates the appropriate PSF price tier.

Table 1 defines the ranges of printer speeds and the points assigned to each printer category.

To determine the printer categories of PSF supported printers, see the IBM® System z® Software Pricing web page:

A printer is considered to be driven by a single printer control unit, even if that control unit drives two printer engines for duplex continuous-forms printing (or certain non-IBM continuous-forms printers that use two coordinated control units).

The rated speed for continuous forms printers is based on the number of landscape pages (8 1/2 inches length) printed per minute when printing only one page across the width of the web. For continuous forms printers with wide webs (17 inches or greater width), the maximum rated speed is based on the number of pages printed per minute when printing two portrait pages (11 inches length) side by side across the width of the web. For continuous forms duplex printers, the maximum rated speed is what is advertised for the duplex printer system.
