- First of all, are you using VMS, Ultrix, or UNIX to print? Each of these
- environments provides different mechanisms for error handling. For example,
- in Ultrix (and some Unices), you need to use -Mkeep to get errors reported
- as mail messages.
-
- As to the actual problem, here are four possibilities:
-
- 1.) Wrong fonts: The LPS20 uses the "DEC 29" fonts, while the others
- you mentioned use the "standard 35"> If there is interest, I can
- post font lists for you.
-
- 2.) Use of the cexec operator. The other printers are 68000-based and
- support the cexec operator, which may be used on Macintosh systems
- to download image- or font-smoothing code or a TrueType rasterizer.
- This code is 68000 assembler, and will obviously not work on the
- VAX-based LPS20, or any other non-68000 controller. It also would
- fail on Level 2 printers.
-
- 3.) Reliance on device-specific operators. This unfortunately includes
- a small number of fairly basic operators, like "letter". Again, you
- might succeed on a number of printers, and fail on a bunch of
- others.
-
- 4.) Implementation limits. Depending on the environment, some of the
- stacks
- and VM are used up by the Symbionts, Translators, etc. This could
- lead
- to VMlimit, Stackoverflow, or other errors.
-
- If you still need help, please post more error info, either by using an
- error
- handler or by capturing the error messages from the printer.
