faxes after they have been received. It is advisable to print and delete the received files routinely, since a single fax page may easily take up several hundred blocks of disk space.
CompuFax may be set up to print received faxes automatically and then delete them. This is the recommended procedure for sites where this will not cause security or distribution difficulties, as this gives reasonable assurances that available disk space will not be exceeded.
5.3 Printing Faxes
Since faxes are received as T4 (compressed bitmap) files, the printing routine must convert the T4 input file into a PCL (Printer Control Language) file, which is then spooled to a laser printer. The PCL file is automatically deleted after it is printed, while the T4 input file optionally may be deleted, as determined by the
/[NO]DELETE qualifier, explained below. Currently, the only type of printer supported is the HP LaserJet or compatible, using PCL. It is expected that in the future other printers will be supported, such as LN03 (sixel) type printers, depending on demand. The HP printer that was used for development was the HP LaserJet model 4M, which uses PCL 5. Earlier models of HP LaserJet should also work, but may be slower and may require a different value for the / MODEL qualifier. See the explanation for that qualifier below.
Printer options may be set in the FAX.OPTIONS file, using the PRINTER command. These options are activated at CompuFax startup. Printer options may also be specified from the FAX> command line, using the SET PRINTER command, to override the startup values. If your system does not have a fax printer, you can omit the PRINTER command from the FAX.OPTIONS file, or include it with / NORECEIVE and
/NOSEND qualifiers. In the FAX.OPTIONS file the PRINTER command may exist or be omitted. When used, all qualifiers are optional. Default values are assigned to unspecified qualifiers, as shown in the table below.

The / [NO]BEST_WAY qualifier determines whether the CompuFax printer driver should use the most efficient method of data compression available for this model printer. Default is / BEST_WAY, which minimizes the amount of time required to copy the data to the printer, which is normally the main factor in printing delays; however, when reducing CPU overhead is more important than printing speed, you may wish
