For some laser printers such as LIPS III and ESC/Page, dviprt for MS-DOS tried to optimize such as data transfer by downloading fonts. When printing is done by a Windows system driver in Windows 95/98 or NT, there is no optimization and printing might be slow.
The Windows 95 and NT printer drivers are improved by the printer manufacturers, and new versions of the drivers might be available. Printing speed may be improved by changing the driver settings or updating the driver.
Printing speed may improve if -cmode: is set to auto-mode or patch2 in the Property Sheets->[Graphic] page and if dviprt is not checked in the dialog of Print. In particular, this may be efficient if no other fonts than TrueType are used for printing.
This remedy setting to patch2 is appropriate only for printing not for preview but under auto-mode an appropriate method is also chosen for preview.
One can also use automatic mode changing function for printing (cf. Current mode:) if necessary. Also, this remedy setting to patch2 does not support printing by dviprt.
Note: Even if the page printer's advertised resolution is 600 dpi, printing may be done in 300 dpi when the printer has insufficient memory, resulting in very slow printing.
If needed, use a built-in dviout for Windows driver (which is particularly efficent for LIPS3,4. ESC/Page. Set raw LIPS IV etc in [Printer] and check dviprt in the dialog of Print), a standard DOS version of dviprt, or a 32-bit version of dviprt. In this case, -LM: and -TM: adjustments may be necessary.
An external printing program can be used from dviout for Windows (dviprt Printing).
