	Hello again everybody!.

	As I mentioned in a previous article I'm having a bit of
	trouble with my newly acquired printer and interface 
	(a Gemini 10X and a Universal/Commodore interface from
	Star Micronics).

	The first problem occurs when I try to print a program listing.
	I do:

		OPEN 4,4,0 (* CBM compatibility A code *)
		CMD 4,"MYPROG":LIST
		PRINT#4: CLOSE4

	This should list the program I have in memory with its name
	on top. The printer head goes all the way to the left margin
	and presses against it doing a terrible noise. If I turn off
	the printer and then on again, the thing prints one line (or
	part of it) with the first character missing. I'm really puzzled
	by this. I've tried 4,4,1, 4,4,7 and even 4,4,5 in the OPEN
	statement with no luck.

	Am I doing something wrong ?. By the way, is there any other
	way of printing a program listing ?.

	The second problem is the following:

	Suppose a variable CC$ in a program contains the function code
	for compressed mode (i.e. CHR$(27)+CHR$(15)).

	If I do PRINT#4,CC$;"HELLO HELLO", it prints the message in 
	compressed mode but the letters are incomplete (i.e. some dots
	of the matrix image are missing). If, on the other hand, I do:

		PRINT#4,CC$;:PRINT#4,"HELLO HELLO"

	everything is fine.

	In general, some times when I put a function code and a message
	in the same PRINT statement something weird happens (like the
	print head banging against the left side and screaming for me
	to push the button and put it out of its misery). If I do it
	in separate PRINT statements I have no problems.

	Are this known bugs of the system or should I use the warranty
	in a hurry ?. I hope somebody out there can help me with this.

	Happy hacking you all !
