The host print transform allows the SCS-to-ASCII or AFP-to-ASCII data stream conversion to take place on the iSeries server instead of on an emulator. Having the conversion take place on the iSeries server provides these advantages:
The host print transform is capable of supporting many different types of ASCII data streams. For example, the Hewlett-Packard printer control language (PCL), the IBM® personal printer data stream (PPDS), and the Epson FX and LQ data streams.
Having the conversion done on the iSeries server ensures that the resultant ASCII data stream provides the same printed output regardless of the emulator that the printer is physically attached to.
The host print transform is based on the 3812 SCS printer emulation of the iSeries Access for Windows workstation function. Using the host print transform, all of the ASCII printers that are connected to an iSeries server can perform a 3812 SCS level of function.
Without host print transform, each emulator supports a limited number of ASCII printers. With the host print transform, most IBM printers and a large number of other printers are supported.
Workstation customizing objects that come with the host print transform can be updated by the user to change or add characteristics to a particular printer. Also, if the host print transform does not have a workstation customizing object for a printer you want to use, you can create your own.
Image output can be printed on PCL printers (Hewlet-Packard LaserJet) or PPDS laser printers (IBM 4019 or 4029).
This support allows you to print incoming faxes from Facsimile Support for iSeries to PCL and PPDS laser printers. This support is available to all emulators discussed under host print transform.
Incoming faxes saved in a folder as RFT:DCA can be printed by using the Print Document (PRTDOC) command. You can also use the Print Fax (PRTFAX) command to direct the incoming faxes directly to an ASCII print device configured to use the host print transform. Host print transform has also been enhanced to do image resolution scaling which allows faxes to be printed in normal size. See Facsimile Support for OS/400® User's Guide for more information.
For the AFP-to-ASCII data stream conversion, there are additional advantages, such as support for AFP font, text, image, and bar code commands.
