240/300 Switchable Printers (Infoprint 4000 Models Only)

Selecting printhead resolution

Printer Definition -> Printer -> Basic -> Printhead Resolution

If your printer has a 240/300 DPI(R) switchable printhead, you will need operator instructions on when and how to switch between the two different resolutions. If all your jobs are developed at a single DPI, for example 240 DPI, you may want to keep the printer at 240 DPI resolution all the time. However, if you have some jobs for 240 DPI and some for 300 DPI, you will need to have some way of separating the jobs by resolution and of notifying the operator when to change the resolution on the printer. This change is done from the touchscreen by selecting the Printer Definition tab and proceeding through the definition steps. The printer normally takes less than 1 minute to complete this operation.

When switching printer resolution, the operator must also switch the libraries for raster fonts. Only 240 DPI raster fonts can print at 240 DPI; only 300 DPI raster fonts can print at 300 DPI. Steps for switching the libraries depend on the PSF software that is driving the printer. For more information, see the appropriate PSF system programming guide.

If your PSF is PSF/MVS 2.2 with APAR OW27622 for Multiple Resolution support, you can set up the PSF printer definition so that the font libraries switch automatically when the printer resolution is changed. See the APAR documentation for details.
